-# benchmark.rb - a performance benchmarking library
-#
-# $Id$
-#
-# Created by Gotoken (gotoken@notwork.org).
-#
-# Documentation by Gotoken (original RD), Lyle Johnson (RDoc conversion), and
-# Gavin Sinclair (editing).
-#++
-#
-# == Overview
-#
-# The Benchmark module provides methods for benchmarking Ruby code, giving
-# detailed reports on the time taken for each task.
-#
-
-# The Benchmark module provides methods to measure and report the time
-# used to execute Ruby code.
-#
-# * Measure the time to construct the string given by the expression
-#   <tt>"a"*1_000_000</tt>:
-#
-#       require 'benchmark'
-#
-#       puts Benchmark.measure { "a"*1_000_000 }
-#
-#   On my machine (FreeBSD 3.2 on P5, 100MHz) this generates:
-#
-#       1.166667   0.050000   1.216667 (  0.571355)
-#
-#   This report shows the user CPU time, system CPU time, the sum of
-#   the user and system CPU times, and the elapsed real time. The unit
-#   of time is seconds.
-#
-# * Do some experiments sequentially using the #bm method:
-#
-#       require 'benchmark'
-#
-#       n = 50000
-#       Benchmark.bm do |x|
-#         x.report { for i in 1..n; a = "1"; end }
-#         x.report { n.times do   ; a = "1"; end }
-#         x.report { 1.upto(n) do ; a = "1"; end }
-#       end
-#
-#   The result:
-#
-#              user     system      total        real
-#          1.033333   0.016667   1.016667 (  0.492106)
-#          1.483333   0.000000   1.483333 (  0.694605)
-#          1.516667   0.000000   1.516667 (  0.711077)
-#
-# * Continuing the previous example, put a label in each report:
-#
-#       require 'benchmark'
-#
-#       n = 50000
-#       Benchmark.bm(7) do |x|
-#         x.report("for:")   { for i in 1..n; a = "1"; end }
-#         x.report("times:") { n.times do   ; a = "1"; end }
-#         x.report("upto:")  { 1.upto(n) do ; a = "1"; end }
-#       end
-#
-# The result:
-#
-#                     user     system      total        real
-#        for:     1.050000   0.000000   1.050000 (  0.503462)
-#        times:   1.533333   0.016667   1.550000 (  0.735473)
-#        upto:    1.500000   0.016667   1.516667 (  0.711239)
-#
-#
-# * The times for some benchmarks depend on the order in which items
-#   are run.  These differences are due to the cost of memory
-#   allocation and garbage collection. To avoid these discrepancies,
-#   the #bmbm method is provided.  For example, to compare ways to
-#   sort an array of floats:
-#
-#       require 'benchmark'
-#
-#       array = (1..1000000).map { rand }
-#
-#       Benchmark.bmbm do |x|
-#         x.report("sort!") { array.dup.sort! }
-#         x.report("sort")  { array.dup.sort  }
-#       end
-#
-#   The result:
-#
-#        Rehearsal -----------------------------------------
-#        sort!  11.928000   0.010000  11.938000 ( 12.756000)

-  # Invokes the block with a <tt>Benchmark::Report</tt> object, which
-  # may be used to collect and report on the results of individual
-  # benchmark tests. Reserves <i>label_width</i> leading spaces for
-  # labels on each line. Prints _caption_ at the top of the
-  # report, and uses _format_ to format each line.
-  # Returns an array of Benchmark::Tms objects.
-  #
-  # If the block returns an array of
-  # <tt>Benchmark::Tms</tt> objects, these will be used to format
-  # additional lines of output. If _label_ parameters are
-  # given, these are used to label these extra lines.
-  #
-  # _Note_: Other methods provide a simpler interface to this one, and are
-  # suitable for nearly all benchmarking requirements.  See the examples in
-  # Benchmark, and the #bm and #bmbm methods.

-  #
-  #     require 'benchmark'

-# == Overview
-#
-# The Common Gateway Interface (CGI) is a simple protocol for passing an HTTP
-# request from a web server to a standalone program, and returning the output
-# to the web browser.  Basically, a CGI program is called with the parameters
-# of the request passed in either in the environment (GET) or via $stdin
-# (POST), and everything it prints to $stdout is returned to the client.
-#
-# This file holds the CGI class.  This class provides functionality for
-# retrieving HTTP request parameters, managing cookies, and generating HTML
-# output.
-#
-# The file CGI::Session provides session management functionality; see that
-# class for more details.
-#
-# See http://www.w3.org/CGI/ for more information on the CGI protocol.
-#
-# == Introduction
-#
-# CGI is a large class, providing several categories of methods, many of which
-# are mixed in from other modules.  Some of the documentation is in this class,
-# some in the modules CGI::QueryExtension and CGI::HtmlExtension.  See
-# CGI::Cookie for specific information on handling cookies, and cgi/session.rb
-# (CGI::Session) for information on sessions.
-#
-# For queries, CGI provides methods to get at environmental variables,
-# parameters, cookies, and multipart request data.  For responses, CGI provides
-# methods for writing output and generating HTML.
-#
-# Read on for more details.  Examples are provided at the bottom.
-#
-# == Queries
-#
-# The CGI class dynamically mixes in parameter and cookie-parsing
-# functionality,  environmental variable access, and support for
-# parsing multipart requests (including uploaded files) from the
-# CGI::QueryExtension module.
-#
-# === Environmental Variables
-#
-# The standard CGI environmental variables are available as read-only
-# attributes of a CGI object.  The following is a list of these variables:
-#
-#
-#   AUTH_TYPE               HTTP_HOST          REMOTE_IDENT
-#   CONTENT_LENGTH          HTTP_NEGOTIATE     REMOTE_USER
-#   CONTENT_TYPE            HTTP_PRAGMA        REQUEST_METHOD
-#   GATEWAY_INTERFACE       HTTP_REFERER       SCRIPT_NAME
-#   HTTP_ACCEPT             HTTP_USER_AGENT    SERVER_NAME
-#   HTTP_ACCEPT_CHARSET     PATH_INFO          SERVER_PORT
-#   HTTP_ACCEPT_ENCODING    PATH_TRANSLATED    SERVER_PROTOCOL
-#   HTTP_ACCEPT_LANGUAGE    QUERY_STRING       SERVER_SOFTWARE
-#   HTTP_CACHE_CONTROL      REMOTE_ADDR
-#   HTTP_FROM               REMOTE_HOST
-#
-#
-# For each of these variables, there is a corresponding attribute with the
-# same name, except all lower case and without a preceding HTTP_.
-# +content_length+ and +server_port+ are integers; the rest are strings.
-#
-# === Parameters
-#
-# The method #params() returns a hash of all parameters in the request as
-# name/value-list pairs, where the value-list is an Array of one or more
-# values.  The CGI object itself also behaves as a hash of parameter names
-# to values, but only returns a single value (as a String) for each
-# parameter name.
-#
-# For instance, suppose the request contains the parameter
-# "favourite_colours" with the multiple values "blue" and "green".  The
-# following behaviour would occur:
-#
-#   cgi.params["favourite_colours"]  # => ["blue", "green"]
-#   cgi["favourite_colours"]         # => "blue"
-#
-# If a parameter does not exist, the former method will return an empty
-# array, the latter an empty string.  The simplest way to test for existence
-# of a parameter is by the #has_key? method.
-#
-# === Cookies
-#
-# HTTP Cookies are automatically parsed from the request.  They are available
-# from the #cookies() accessor, which returns a hash from cookie name to
-# CGI::Cookie object.
-#
-# === Multipart requests
-#
-# If a request's method is POST and its content type is multipart/form-data,
-# then it may contain uploaded files.  These are stored by the QueryExtension
-# module in the parameters of the request.  The parameter name is the name
-# attribute of the file input field, as usual.  However, the value is not
-# a string, but an IO object, either an IOString for small files, or a
-# Tempfile for larger ones.  This object also has the additional singleton
-# methods:
-#
-# #local_path():: the path of the uploaded file on the local filesystem
-# #original_filename():: the name of the file on the client computer
-# #content_type():: the content type of the file
-#
-# == Responses
-#
-# The CGI class provides methods for sending header and content output to
-# the HTTP client, and mixes in methods for programmatic HTML generation
-# from CGI::HtmlExtension and CGI::TagMaker modules.  The precise version of HTML
-# to use for HTML generation is specified at object creation time.
-#
-# === Writing output
-#
-# The simplest way to send output to the HTTP client is using the #out() method.
-# This takes the HTTP headers as a hash parameter, and the body content
-# via a block.  The headers can be generated as a string using the #header()
-# method.  The output stream can be written directly to using the #print()
-# method.
-#
-# === Generating HTML
-#
-# Each HTML element has a corresponding method for generating that
-# element as a String.  The name of this method is the same as that
-# of the element, all lowercase.  The attributes of the element are
-# passed in as a hash, and the body as a no-argument block that evaluates
-# to a String.  The HTML generation module knows which elements are
-# always empty, and silently drops any passed-in body.  It also knows
-# which elements require matching closing tags and which don't.  However,
-# it does not know what attributes are legal for which elements.
-#
-# There are also some additional HTML generation methods mixed in from
-# the CGI::HtmlExtension module.  These include individual methods for the
-# different types of form inputs, and methods for elements that commonly
-# take particular attributes where the attributes can be directly specified
-# as arguments, rather than via a hash.
-#
-# == Examples of use
-#
-# === Get form values
-#
-#   require "cgi"
-#   cgi = CGI.new
-#   value = cgi['field_name']   # <== value string for 'field_name'
-#     # if not 'field_name' included, then return "".
-#   fields = cgi.keys            # <== array of field names
-#
-#   # returns true if form has 'field_name'
-#   cgi.has_key?('field_name')
-#   cgi.has_key?('field_name')
-#   cgi.include?('field_name')
-#
-# CAUTION! cgi['field_name'] returned an Array with the old
-# cgi.rb(included in ruby 1.6)
-#
-# === Get form values as hash
-#
-#   require "cgi"
-#   cgi = CGI.new
-#   params = cgi.params
-#
-# cgi.params is a hash.
-#
-#   cgi.params['new_field_name'] = ["value"]  # add new param
-#   cgi.params['field_name'] = ["new_value"]  # change value
-#   cgi.params.delete('field_name')           # delete param
-#   cgi.params.clear                          # delete all params
-#
-#
-# === Save form values to file
-#
-#   require "pstore"
-#   db = PStore.new("query.db")
-#   db.transaction do
-#     db["params"] = cgi.params
-#   end
-#
-#
-# === Restore form values from file
-#
-#   require "pstore"
-#   db = PStore.new("query.db")
-#   db.transaction do
-#     cgi.params = db["params"]
-#   end
-#
-#
-# === Get multipart form values
-#
-#   require "cgi"
-#   cgi = CGI.new
-#   value = cgi['field_name']   # <== value string for 'field_name'
-#   value.read                  # <== body of value
-#   value.local_path            # <== path to local file of value
-#   value.original_filename     # <== original filename of value
-#   value.content_type          # <== content_type of value
-#
-# and value has StringIO or Tempfile class methods.
-#
-# === Get cookie values
-#
-#   require "cgi"
-#   cgi = CGI.new
-#   values = cgi.cookies['name']  # <== array of 'name'
-#     # if not 'name' included, then return [].
-#   names = cgi.cookies.keys      # <== array of cookie names
-#
-# and cgi.cookies is a hash.
-#
-# === Get cookie objects
-#
-#   require "cgi"
-#   cgi = CGI.new
-#   for name, cookie in cgi.cookies
-#     cookie.expires = Time.now + 30
-#   end
-#   cgi.out("cookie" => cgi.cookies) {"string"}
-#
-#   cgi.cookies # { "name1" => cookie1, "name2" => cookie2, ... }
-#
-#   require "cgi"
-#   cgi = CGI.new
-#   cgi.cookies['name'].expires = Time.now + 30
-#   cgi.out("cookie" => cgi.cookies['name']) {"string"}
-#
-# === Print http header and html string to $DEFAULT_OUTPUT ($>)
-#
-#   require "cgi"
-#   cgi = CGI.new("html3")  # add HTML generation methods
-#   cgi.out() do
-#     cgi.html() do
-#       cgi.head{ cgi.title{"TITLE"} } +
-#       cgi.body() do
-#         cgi.form() do
-#           cgi.textarea("get_text") +
-#           cgi.br +
-#           cgi.submit
-#         end +
-#         cgi.pre() do
-#           CGI::escapeHTML(
-#             "params: " + cgi.params.inspect + "\n" +
-#             "cookies: " + cgi.cookies.inspect + "\n" +
-#             ENV.collect() do |key, value|
-#               key + " --> " + value + "\n"
-#             end.join("")
-#           )
-#         end
-#       end
-#     end
-#   end

-class CGI
-
-  # == Overview
-  #
-  # This file provides the CGI::Session class, which provides session
-  # support for CGI scripts.  A session is a sequence of HTTP requests
-  # and responses linked together and associated with a single client.
-  # Information associated with the session is stored
-  # on the server between requests.  A session id is passed between client
-  # and server with every request and response, transparently
-  # to the user.  This adds state information to the otherwise stateless
-  # HTTP request/response protocol.
-  #
-  # == Lifecycle
-  #
-  # A CGI::Session instance is created from a CGI object.  By default,
-  # this CGI::Session instance will start a new session if none currently
-  # exists, or continue the current session for this client if one does
-  # exist.  The +new_session+ option can be used to either always or
-  # never create a new session.  See #new() for more details.
-  #
-  # #delete() deletes a session from session storage.  It
-  # does not however remove the session id from the client.  If the client
-  # makes another request with the same id, the effect will be to start
-  # a new session with the old session's id.
-  #
-  # == Setting and retrieving session data.
-  #
-  # The Session class associates data with a session as key-value pairs.
-  # This data can be set and retrieved by indexing the Session instance
-  # using '[]', much the same as hashes (although other hash methods
-  # are not supported).
-  #
-  # When session processing has been completed for a request, the
-  # session should be closed using the close() method.  This will
-  # store the session's state to persistent storage.  If you want
-  # to store the session's state to persistent storage without
-  # finishing session processing for this request, call the update()
-  # method.
-  #
-  # == Storing session state
-  #
-  # The caller can specify what form of storage to use for the session's
-  # data with the +database_manager+ option to CGI::Session::new.  The
-  # following storage classes are provided as part of the standard library:
-  #
-  # CGI::Session::FileStore:: stores data as plain text in a flat file.  Only
-  #                           works with String data.  This is the default
-  #                           storage type.
-  # CGI::Session::MemoryStore:: stores data in an in-memory hash.  The data
-  #                             only persists for as long as the current ruby
-  #                             interpreter instance does.
-  # CGI::Session::PStore:: stores data in Marshalled format.  Provided by
-  #                        cgi/session/pstore.rb.  Supports data of any type,
-  #                        and provides file-locking and transaction support.
-  #
-  # Custom storage types can also be created by defining a class with
-  # the following methods:
-  #
-  #    new(session, options)
-  #    restore  # returns hash of session data.
-  #    update
-  #    close
-  #    delete
-  #
-  # Changing storage type mid-session does not work.  Note in particular
-  # that by default the FileStore and PStore session data files have the
-  # same name.  If your application switches from one to the other without
-  # making sure that filenames will be different
-  # and clients still have old sessions lying around in cookies, then
-  # things will break nastily!
-  #
-  # == Maintaining the session id.
-  #
-  # Most session state is maintained on the server.  However, a session
-  # id must be passed backwards and forwards between client and server
-  # to maintain a reference to this session state.
-  #
-  # The simplest way to do this is via cookies.  The CGI::Session class
-  # provides transparent support for session id communication via cookies
-  # if the client has cookies enabled.
-  #
-  # If the client has cookies disabled, the session id must be included
-  # as a parameter of all requests sent by the client to the server.  The
-  # CGI::Session class in conjunction with the CGI class will transparently
-  # add the session id as a hidden input field to all forms generated
-  # using the CGI#form() HTML generation method.  No built-in support is
-  # provided for other mechanisms, such as URL re-writing.  The caller is
-  # responsible for extracting the session id from the session_id
-  # attribute and manually encoding it in URLs and adding it as a hidden
-  # input to HTML forms created by other mechanisms.  Also, session expiry
-  # is not automatically handled.
-  #
-  # == Examples of use
-  #
-  # === Setting the user's name
-  #
-  #   require 'cgi'
-  #   require 'cgi/session'
-  #   require 'cgi/session/pstore'     # provides CGI::Session::PStore
-  #
-  #   cgi = CGI.new("html4")
-  #
-  #   session = CGI::Session.new(cgi,
-  #       'database_manager' => CGI::Session::PStore,  # use PStore
-  #       'session_key' => '_rb_sess_id',              # custom session key
-  #       'session_expires' => Time.now + 30 * 60,     # 30 minute timeout
-  #       'prefix' => 'pstore_sid_')                   # PStore option
-  #   if cgi.has_key?('user_name') and cgi['user_name'] != ''
-  #       # coerce to String: cgi[] returns the
-  #       # string-like CGI::QueryExtension::Value
-  #       session['user_name'] = cgi['user_name'].to_s
-  #   elsif !session['user_name']
-  #       session['user_name'] = "guest"
-  #   end
-  #   session.close
-  #
-  # === Creating a new session safely
-  #
-  #   require 'cgi'
-  #   require 'cgi/session'
-  #
-  #   cgi = CGI.new("html4")
-  #
-  #   # We make sure to delete an old session if one exists,
-  #   # not just to free resources, but to prevent the session
-  #   # from being maliciously hijacked later on.
-  #   begin
-  #       session = CGI::Session.new(cgi, 'new_session' => false)
-  #       session.delete
-  #   rescue ArgumentError  # if no old session

-    # Create a new CGI::Session object for +request+.

-    # +request+ is an instance of the +CGI+ class (see cgi.rb).
-    # +option+ is a hash of options for initialising this

-    # recognised:
-    #
-    # session_key:: the parameter name used for the session id.
-    #               Defaults to '_session_id'.
-    # session_id:: the session id to use.  If not provided, then
-    #              it is retrieved from the +session_key+ parameter
-    #              of the request, or automatically generated for
-    #              a new session.
-    # new_session:: if true, force creation of a new session.  If not set,
-    #               a new session is only created if none currently
-    #               exists.  If false, a new session is never created,
-    #               and if none currently exists and the +session_id+
-    #               option is not set, an ArgumentError is raised.
-    # database_manager:: the name of the class providing storage facilities
-    #                    for session state persistence.  Built-in support
-    #                    is provided for +FileStore+ (the default),
-    #                    +MemoryStore+, and +PStore+ (from
-    #                    cgi/session/pstore.rb).  See the documentation for
-    #                    these classes for more details.
-    #
-    # The following options are also recognised, but only apply if the
-    # session id is stored in a cookie.
-    #
-    # session_expires:: the time the current session expires, as a
-    #                   +Time+ object.  If not set, the session will terminate
-    #                   when the user's browser is closed.
-    # session_domain:: the hostname domain for which this session is valid.
-    #                  If not set, defaults to the hostname of the server.
-    # session_secure:: if +true+, this session will only work over HTTPS.
-    # session_path:: the path for which this session applies.  Defaults
-    #                to the directory of the CGI script.
-    #
-    # +option+ is also passed on to the session storage class initializer; see
-    # the documentation for each session storage class for the options
-    # they support.
-    #
-    # The retrieved or created session is automatically added to +request+
-    # as a cookie, and also to its +output_hidden+ table, which is used

-# encoding: US-ASCII
-# = csv.rb -- CSV Reading and Writing
-#
-#  Created by James Edward Gray II on 2005-10-31.
-#  Copyright 2005 James Edward Gray II. You can redistribute or modify this code
-#  under the terms of Ruby's license.
-#
-# See CSV for documentation.
-#
-# == Description
-#
-# Welcome to the new and improved CSV.
-#
-# This version of the CSV library began its life as FasterCSV.  FasterCSV was
-# intended as a replacement to Ruby's then standard CSV library.  It was
-# designed to address concerns users of that library had and it had three
-# primary goals:
-#
-# 1.  Be significantly faster than CSV while remaining a pure Ruby library.
-# 2.  Use a smaller and easier to maintain code base.  (FasterCSV eventually
-#     grew larger, was also but considerably richer in features.  The parsing
-#     core remains quite small.)
-# 3.  Improve on the CSV interface.
-#
-# Obviously, the last one is subjective.  I did try to defer to the original
-# interface whenever I didn't have a compelling reason to change it though, so
-# hopefully this won't be too radically different.
-#
-# We must have met our goals because FasterCSV was renamed to CSV and replaced
-# the original library as of Ruby 1.9. If you are migrating code from 1.8 or
-# earlier, you may have to change your code to comply with the new interface.
-#
-# == What's Different From the Old CSV?
-#
-# I'm sure I'll miss something, but I'll try to mention most of the major
-# differences I am aware of, to help others quickly get up to speed:
-#
-# === CSV Parsing
-#
-# * This parser is m17n aware.  See CSV for full details.
-# * This library has a stricter parser and will throw MalformedCSVErrors on
-#   problematic data.
-# * This library has a less liberal idea of a line ending than CSV.  What you
-#   set as the <tt>:row_sep</tt> is law.  It can auto-detect your line endings
-#   though.
-# * The old library returned empty lines as <tt>[nil]</tt>.  This library calls
-#   them <tt>[]</tt>.
-# * This library has a much faster parser.
-#
-# === Interface
-#
-# * CSV now uses Hash-style parameters to set options.
-# * CSV no longer has generate_row() or parse_row().
-# * The old CSV's Reader and Writer classes have been dropped.
-# * CSV::open() is now more like Ruby's open().
-# * CSV objects now support most standard IO methods.
-# * CSV now has a new() method used to wrap objects like String and IO for
-#   reading and writing.
-# * CSV::generate() is different from the old method.
-# * CSV no longer supports partial reads.  It works line-by-line.
-# * CSV no longer allows the instance methods to override the separators for
-#   performance reasons.  They must be set in the constructor.
-#
-# If you use this library and find yourself missing any functionality I have
-# trimmed, please {let me know}[mailto:james@grayproductions.net].
-#
-# == Documentation
-#
-# See CSV for documentation.
-#
-# == What is CSV, really?
-#
-# CSV maintains a pretty strict definition of CSV taken directly from
-# {the RFC}[http://www.ietf.org/rfc/rfc4180.txt].  I relax the rules in only one
-# place and that is to make using this library easier.  CSV will parse all valid
-# CSV.
-#
-# What you don't want to do is feed CSV invalid data.  Because of the way the
-# CSV format works, it's common for a parser to need to read until the end of
-# the file to be sure a field is invalid.  This eats a lot of time and memory.
-#
-# Luckily, when working with invalid CSV, Ruby's built-in methods will almost
-# always be superior in every way.  For example, parsing non-quoted fields is as
-# easy as:
-#
-#   data.split(",")
-#
-# == Questions and/or Comments
-#
-# Feel free to email {James Edward Gray II}[mailto:james@grayproductions.net]
-# with any questions.

-# This class provides a complete interface to CSV files and data.  It offers
-# tools to enable you to read and write to and from Strings or IO objects, as
-# needed.
-#
-# == Reading
-#
-# === From a File
-#
-# ==== A Line at a Time
-#
-#   CSV.foreach("path/to/file.csv") do |row|
-#     # use row here...
-#   end
-#
-# ==== All at Once
-#
-#   arr_of_arrs = CSV.read("path/to/file.csv")
-#
-# === From a String
-#
-# ==== A Line at a Time
-#
-#   CSV.parse("CSV,data,String") do |row|
-#     # use row here...
-#   end
-#
-# ==== All at Once
-#
-#   arr_of_arrs = CSV.parse("CSV,data,String")
-#
-# == Writing
-#
-# === To a File
-#
-#   CSV.open("path/to/file.csv", "wb") do |csv|
-#     csv << ["row", "of", "CSV", "data"]
-#     csv << ["another", "row"]
-#     # ...
-#   end
-#
-# === To a String
-#
-#   csv_string = CSV.generate do |csv|
-#     csv << ["row", "of", "CSV", "data"]
-#     csv << ["another", "row"]
-#     # ...
-#   end
-#
-# == Convert a Single Line
-#
-#   csv_string = ["CSV", "data"].to_csv   # to CSV
-#   csv_array  = "CSV,String".parse_csv   # from CSV
-#
-# == Shortcut Interface
-#
-#   CSV             { |csv_out| csv_out << %w{my data here} }  # to $stdout
-#   CSV(csv = "")   { |csv_str| csv_str << %w{my data here} }  # to a String
-#   CSV($stderr)    { |csv_err| csv_err << %w{my data here} }  # to $stderr
-#   CSV($stdin)     { |csv_in|  csv_in.each { |row| p row } }  # from $stdin
-#
-# == Advanced Usage
-#
-# === Wrap an IO Object
-#
-#   csv = CSV.new(io, options)
-#   # ... read (with gets() or each()) from and write (with <<) to csv here ...
-#
-# == CSV and Character Encodings (M17n or Multilingualization)
-#
-# This new CSV parser is m17n savvy.  The parser works in the Encoding of the IO
-# or String object being read from or written to.  Your data is never transcoded
-# (unless you ask Ruby to transcode it for you) and will literally be parsed in
-# the Encoding it is in.  Thus CSV will return Arrays or Rows of Strings in the
-# Encoding of your data.  This is accomplished by transcoding the parser itself
-# into your Encoding.
-#
-# Some transcoding must take place, of course, to accomplish this multiencoding
-# support.  For example, <tt>:col_sep</tt>, <tt>:row_sep</tt>, and
-# <tt>:quote_char</tt> must be transcoded to match your data.  Hopefully this
-# makes the entire process feel transparent, since CSV's defaults should just
-# magically work for you data.  However, you can set these values manually in
-# the target Encoding to avoid the translation.
-#
-# It's also important to note that while all of CSV's core parser is now
-# Encoding agnostic, some features are not.  For example, the built-in
-# converters will try to transcode data to UTF-8 before making conversions.
-# Again, you can provide custom converters that are aware of your Encodings to
-# avoid this translation.  It's just too hard for me to support native
-# conversions in all of Ruby's Encodings.
-#
-# Anyway, the practical side of this is simple:  make sure IO and String objects
-# passed into CSV have the proper Encoding set and everything should just work.
-# CSV methods that allow you to open IO objects (CSV::foreach(), CSV::open(),
-# CSV::read(), and CSV::readlines()) do allow you to specify the Encoding.
-#
-# One minor exception comes when generating CSV into a String with an Encoding
-# that is not ASCII compatible.  There's no existing data for CSV to use to
-# prepare itself and thus you will probably need to manually specify the desired
-# Encoding for most of those cases.  It will try to guess using the fields in a
-# row of output though, when using CSV::generate_line() or Array#to_csv().
-#
-# I try to point out any other Encoding issues in the documentation of methods
-# as they come up.
-#
-# This has been tested to the best of my ability with all non-"dummy" Encodings
-# Ruby ships with.  However, it is brave new code and may have some bugs.
-# Please feel free to {report}[mailto:james@grayproductions.net] any issues you
-# find with it.

-# = delegate -- Support for the Delegation Pattern
-#
-# Documentation by James Edward Gray II and Gavin Sinclair
-
-##
-# This library provides three different ways to delegate method calls to an
-# object.  The easiest to use is SimpleDelegator.  Pass an object to the
-# constructor and all methods supported by the object will be delegated.  This
-# object can be changed later.
-#
-# Going a step further, the top level DelegateClass method allows you to easily
-# setup delegation through class inheritance.  This is considerably more
-# flexible and thus probably the most common use for this library.
-#
-# Finally, if you need full control over the delegation scheme, you can inherit
-# from the abstract class Delegator and customize as needed.  (If you find
-# yourself needing this control, have a look at Forwardable which is also in
-# the standard library.  It may suit your needs better.)
-#
-# SimpleDelegator's implementation serves as a nice example if the use of
-# Delegator:
-#
-#   class SimpleDelegator < Delegator
-#     def initialize(obj)
-#       super                  # pass obj to Delegator constructor, required
-#       @delegate_sd_obj = obj # store obj for future use
-#     end
-#
-#     def __getobj__
-#       @delegate_sd_obj # return object we are delegating to, required
-#     end
-#
-#     def __setobj__(obj)
-#       @delegate_sd_obj = obj # change delegation object,
-#                              # a feature we're providing
-#     end
-#   end
-#
-# == Notes
-#
-# Be advised, RDoc will not detect delegated methods.

-#
-# == Overview
-#
-# dRuby is a distributed object system for Ruby.  It is written in
-# pure Ruby and uses its own protocol.  No add-in services are needed
-# beyond those provided by the Ruby runtime, such as TCP sockets.  It
-# does not rely on or interoperate with other distributed object
-# systems such as CORBA, RMI, or .NET.
-#
-# dRuby allows methods to be called in one Ruby process upon a Ruby
-# object located in another Ruby process, even on another machine.
-# References to objects can be passed between processes.  Method
-# arguments and return values are dumped and loaded in marshalled
-# format.  All of this is done transparently to both the caller of the
-# remote method and the object that it is called upon.
-#
-# An object in a remote process is locally represented by a
-# DRb::DRbObject instance.  This acts as a sort of proxy for the
-# remote object.  Methods called upon this DRbObject instance are
-# forwarded to its remote object.  This is arranged dynamically at run
-# time.  There are no statically declared interfaces for remote
-# objects, such as CORBA's IDL.
-#
-# dRuby calls made into a process are handled by a DRb::DRbServer
-# instance within that process.  This reconstitutes the method call,
-# invokes it upon the specified local object, and returns the value to
-# the remote caller.  Any object can receive calls over dRuby.  There
-# is no need to implement a special interface, or mixin special
-# functionality.  Nor, in the general case, does an object need to
-# explicitly register itself with a DRbServer in order to receive
-# dRuby calls.
-#
-# One process wishing to make dRuby calls upon another process must
-# somehow obtain an initial reference to an object in the remote
-# process by some means other than as the return value of a remote
-# method call, as there is initially no remote object reference it can
-# invoke a method upon.  This is done by attaching to the server by
-# URI.  Each DRbServer binds itself to a URI such as
-# 'druby://example.com:8787'.  A DRbServer can have an object attached
-# to it that acts as the server's *front* *object*.  A DRbObject can
-# be explicitly created from the server's URI.  This DRbObject's
-# remote object will be the server's front object.  This front object
-# can then return references to other Ruby objects in the DRbServer's
-# process.
-#
-# Method calls made over dRuby behave largely the same as normal Ruby
-# method calls made within a process.  Method calls with blocks are
-# supported, as are raising exceptions.  In addition to a method's
-# standard errors, a dRuby call may also raise one of the
-# dRuby-specific errors, all of which are subclasses of DRb::DRbError.
-#
-# Any type of object can be passed as an argument to a dRuby call or
-# returned as its return value.  By default, such objects are dumped
-# or marshalled at the local end, then loaded or unmarshalled at the
-# remote end.  The remote end therefore receives a copy of the local
-# object, not a distributed reference to it; methods invoked upon this
-# copy are executed entirely in the remote process, not passed on to
-# the local original.  This has semantics similar to pass-by-value.
-#
-# However, if an object cannot be marshalled, a dRuby reference to it
-# is passed or returned instead.  This will turn up at the remote end
-# as a DRbObject instance.  All methods invoked upon this remote proxy
-# are forwarded to the local object, as described in the discussion of
-# DRbObjects.  This has semantics similar to the normal Ruby
-# pass-by-reference.
-#
-# The easiest way to signal that we want an otherwise marshallable
-# object to be passed or returned as a DRbObject reference, rather
-# than marshalled and sent as a copy, is to include the
-# DRb::DRbUndumped mixin module.
-#
-# dRuby supports calling remote methods with blocks.  As blocks (or
-# rather the Proc objects that represent them) are not marshallable,
-# the block executes in the local, not the remote, context.  Each
-# value yielded to the block is passed from the remote object to the
-# local block, then the value returned by each block invocation is
-# passed back to the remote execution context to be collected, before
-# the collected values are finally returned to the local context as
-# the return value of the method invocation.
-#
-# == Examples of usage
-#
-# For more dRuby samples, see the +samples+ directory in the full
-# dRuby distribution.
-#
-# === dRuby in client/server mode
-#
-# This illustrates setting up a simple client-server drb
-# system.  Run the server and client code in different terminals,
-# starting the server code first.
-#
-# ==== Server code
-#
-#   require 'drb/drb'
-#
-#   # The URI for the server to connect to
-#   URI="druby://localhost:8787"
-#
-#   class TimeServer
-#
-#     def get_current_time
-#       return Time.now
-#     end
-#
-#   end
-#
-#   # The object that handles requests on the server
-#   FRONT_OBJECT=TimeServer.new
-#
-#   $SAFE = 1   # disable eval() and friends

-#   DRb.start_service(URI, FRONT_OBJECT)
-#   # Wait for the drb server thread to finish before exiting.
-#   DRb.thread.join
-#
-# ==== Client code

-#   require 'drb/drb'
-#
-#   # The URI to connect to
-#   SERVER_URI="druby://localhost:8787"
-#
-#   # Start a local DRbServer to handle callbacks.
-#   #
-#   # Not necessary for this small example, but will be required
-#   # as soon as we pass a non-marshallable object as an argument

-#   timeserver = DRbObject.new_with_uri(SERVER_URI)
-#   puts timeserver.get_current_time
-#
-# === Remote objects under dRuby
-#
-# This example illustrates returning a reference to an object
-# from a dRuby call.  The Logger instances live in the server
-# process.  References to them are returned to the client process,
-# where methods can be invoked upon them.  These methods are
-# executed in the server process.
-#
-# ==== Server code
-#
-#   require 'drb/drb'
-#
-#   URI="druby://localhost:8787"
-#
-#   class Logger
-#
-#       # Make dRuby send Logger instances as dRuby references,
-#       # not copies.
-#       include DRb::DRbUndumped
-#
-#       def initialize(n, fname)
-#           @name = n
-#           @filename = fname
-#       end
-#
-#       def log(message)
-#           File.open(@filename, "a") do |f|
-#               f.puts("#{Time.now}: #{@name}: #{message}")
-#           end
-#       end
-#
-#   end
-#
-#   # We have a central object for creating and retrieving loggers.
-#   # This retains a local reference to all loggers created.  This
-#   # is so an existing logger can be looked up by name, but also
-#   # to prevent loggers from being garbage collected.  A dRuby
-#   # reference to an object is not sufficient to prevent it being
-#   # garbage collected!
-#   class LoggerFactory
-#
-#       def initialize(bdir)
-#           @basedir = bdir
-#           @loggers = {}
-#       end
-#
-#       def get_logger(name)
-#           if !@loggers.has_key? name
-#               # make the filename safe, then declare it to be so
-#               fname = name.gsub(/[.\/]/, "_").untaint
-#               @loggers[name] = Logger.new(name, @basedir + "/" + fname)
-#           end
-#           return @loggers[name]
-#       end
-#
-#   end
-#
-#   FRONT_OBJECT=LoggerFactory.new("/tmp/dlog")
-#
-#   $SAFE = 1   # disable eval() and friends
-#
-#   DRb.start_service(URI, FRONT_OBJECT)
-#   DRb.thread.join
-#
-# ==== Client code
-#
-#   require 'drb/drb'
-#
-#   SERVER_URI="druby://localhost:8787"
-#
-#   DRb.start_service
-#
-#   log_service=DRbObject.new_with_uri(SERVER_URI)
-#
-#   ["loga", "logb", "logc"].each do |logname|
-#
-#       logger=log_service.get_logger(logname)
-#
-#       logger.log("Hello, world!")
-#       logger.log("Goodbye, world!")
-#       logger.log("=== EOT ===")
-#
-#   end
-#
-# == Security
-#
-# As with all network services, security needs to be considered when
-# using dRuby.  By allowing external access to a Ruby object, you are
-# not only allowing outside clients to call the methods you have
-# defined for that object, but by default to execute arbitrary Ruby
-# code on your server.  Consider the following:
-#
-#    # !!! UNSAFE CODE !!!
-#    ro = DRbObject::new_with_uri("druby://your.server.com:8989")
-#    class << ro
-#      undef :instance_eval  # force call to be passed to remote object
-#    end
-#    ro.instance_eval("`rm -rf *`")
-#
-# The dangers posed by instance_eval and friends are such that a
-# DRbServer should generally be run with $SAFE set to at least
-# level 1.  This will disable eval() and related calls on strings
-# passed across the wire.  The sample usage code given above follows
-# this practice.
-#
-# A DRbServer can be configured with an access control list to
-# selectively allow or deny access from specified IP addresses.  The
-# main druby distribution provides the ACL class for this purpose.  In
-# general, this mechanism should only be used alongside, rather than
-# as a replacement for, a good firewall.
-#
-# == dRuby internals
-#
-# dRuby is implemented using three main components: a remote method
-# call marshaller/unmarshaller; a transport protocol; and an
-# ID-to-object mapper.  The latter two can be directly, and the first
-# indirectly, replaced, in order to provide different behaviour and
-# capabilities.
-#
-# Marshalling and unmarshalling of remote method calls is performed by
-# a DRb::DRbMessage instance.  This uses the Marshal module to dump
-# the method call before sending it over the transport layer, then
-# reconstitute it at the other end.  There is normally no need to
-# replace this component, and no direct way is provided to do so.
-# However, it is possible to implement an alternative marshalling
-# scheme as part of an implementation of the transport layer.
-#
-# The transport layer is responsible for opening client and server
-# network connections and forwarding dRuby request across them.
-# Normally, it uses DRb::DRbMessage internally to manage marshalling
-# and unmarshalling.  The transport layer is managed by
-# DRb::DRbProtocol.  Multiple protocols can be installed in
-# DRbProtocol at the one time; selection between them is determined by
-# the scheme of a dRuby URI.  The default transport protocol is
-# selected by the scheme 'druby:', and implemented by
-# DRb::DRbTCPSocket.  This uses plain TCP/IP sockets for
-# communication.  An alternative protocol, using UNIX domain sockets,
-# is implemented by DRb::DRbUNIXSocket in the file drb/unix.rb, and
-# selected by the scheme 'drbunix:'.  A sample implementation over
-# HTTP can be found in the samples accompanying the main dRuby
-# distribution.
-#
-# The ID-to-object mapping component maps dRuby object ids to the
-# objects they refer to, and vice versa.  The implementation to use
-# can be specified as part of a DRb::DRbServer's configuration.  The
-# default implementation is provided by DRb::DRbIdConv.  It uses an
-# object's ObjectSpace id as its dRuby id.  This means that the dRuby
-# reference to that object only remains meaningful for the lifetime of
-# the object's process and the lifetime of the object within that
-# process.  A modified implementation is provided by DRb::TimerIdConv
-# in the file drb/timeridconv.rb.  This implementation retains a local
-# reference to all objects exported over dRuby for a configurable
-# period of time (defaulting to ten minutes), to prevent them being
-# garbage-collected within this time.  Another sample implementation
-# is provided in sample/name.rb in the main dRuby distribution.  This
-# allows objects to specify their own id or "name".  A dRuby reference
-# can be made persistent across processes by having each process
-# register an object using the same dRuby name.

-  # Module managing the underlying network protocol(s) used by drb.
-  #
-  # By default, drb uses the DRbTCPSocket protocol.  Other protocols
-  # can be defined.  A protocol must define the following class methods:
-  #
-  #   [open(uri, config)] Open a client connection to the server at +uri+,
-  #                       using configuration +config+.  Return a protocol
-  #                       instance for this connection.
-  #   [open_server(uri, config)] Open a server listening at +uri+,
-  #                              using configuration +config+.  Return a
-  #                              protocol instance for this listener.
-  #   [uri_option(uri, config)] Take a URI, possibly containing an option
-  #                             component (e.g. a trailing '?param=val'),
-  #                             and return a [uri, option] tuple.
-  #
-  # All of these methods should raise a DRbBadScheme error if the URI
-  # does not identify the protocol they support (e.g. "druby:" for
-  # the standard Ruby protocol).  This is how the DRbProtocol module,
-  # given a URI, determines which protocol implementation serves that
-  # protocol.
-  #
-  # The protocol instance returned by #open_server must have the
-  # following methods:
-  #
-  # [accept] Accept a new connection to the server.  Returns a protocol
-  #          instance capable of communicating with the client.
-  # [close] Close the server connection.
-  # [uri] Get the URI for this server.
-  #
-  # The protocol instance returned by #open must have the following methods:
-  #
-  # [send_request (ref, msg_id, arg, b)]
-  #      Send a request to +ref+ with the given message id and arguments.
-  #      This is most easily implemented by calling DRbMessage.send_request,
-  #      providing a stream that sits on top of the current protocol.
-  # [recv_reply]
-  #      Receive a reply from the server and return it as a [success-boolean,
-  #      reply-value] pair.  This is most easily implemented by calling
-  #      DRb.recv_reply, providing a stream that sits on top of the
-  #      current protocol.
-  # [alive?]
-  #      Is this connection still alive?
-  # [close]
-  #      Close this connection.
-  #
-  # The protocol instance returned by #open_server().accept() must have
-  # the following methods:
-  #
-  # [recv_request]
-  #     Receive a request from the client and return a [object, message,
-  #     args, block] tuple.  This is most easily implemented by calling
-  #     DRbMessage.recv_request, providing a stream that sits on top of
-  #     the current protocol.
-  # [send_reply(succ, result)]
-  #     Send a reply to the client.  This is most easily implemented
-  #     by calling DRbMessage.send_reply, providing a stream that sits
-  #     on top of the current protocol.
-  # [close]
-  #     Close this connection.
-  #
-  # A new protocol is registered with the DRbProtocol module using
-  # the add_protocol method.

-# = ERB -- Ruby Templating
-#
-# Author:: Masatoshi SEKI
-# Documentation:: James Edward Gray II, Gavin Sinclair, and Simon Chiang
-#
-# See ERB for primary documentation and ERB::Util for a couple of utility
-# routines.
-#

-# = ERB -- Ruby Templating
-#
-# == Introduction
-#
-# ERB provides an easy to use but powerful templating system for Ruby.  Using
-# ERB, actual Ruby code can be added to any plain text document for the
-# purposes of generating document information details and/or flow control.
-#
-# A very simple example is this:
-#
-#   require 'erb'
-#
-#   x = 42
-#   template = ERB.new <<-EOF
-#     The value of x is: <%= x %>
-#   EOF
-#   puts template.result(binding)
-#
-# <em>Prints:</em> The value of x is: 42
-#
-# More complex examples are given below.
-#
-#
-# == Recognized Tags
-#
-# ERB recognizes certain tags in the provided template and converts them based
-# on the rules below:
-#
-#   <% Ruby code -- inline with output %>
-#   <%= Ruby expression -- replace with result %>
-#   <%# comment -- ignored -- useful in testing %>
-#   % a line of Ruby code -- treated as <% line %> (optional -- see ERB.new)
-#   %% replaced with % if first thing on a line and % processing is used
-#   <%% or %%> -- replace with <% or %> respectively
-#
-# All other text is passed through ERB filtering unchanged.
-#
-#
-# == Options
-#
-# There are several settings you can change when you use ERB:
-# * the nature of the tags that are recognized;
-# * the value of <tt>$SAFE</tt> under which the template is run;
-# * the binding used to resolve local variables in the template.
-#
-# See the ERB.new and ERB#result methods for more detail.
-#
-# == Character encodings
-#
-# ERB (or ruby code generated by ERB) returns a string in the same
-# character encoding as the input string.  When the input string has
-# a magic comment, however, it returns a string in the encoding specified
-# by the magic comment.
-#
-#   # -*- coding: UTF-8 -*-
-#   require 'erb'
-#
-#   template = ERB.new <<EOF
-#   <%#-*- coding: Big5 -*-%>
-#     \_\_ENCODING\_\_ is <%= \_\_ENCODING\_\_ %>.
-#   EOF
-#   puts template.result
-#
-# <em>Prints:</em> \_\_ENCODING\_\_ is Big5.
-#
-#
-# == Examples
-#
-# === Plain Text
-#
-# ERB is useful for any generic templating situation.  Note that in this example, we use the
-# convenient "% at start of line" tag, and we quote the template literally with
-# <tt>%q{...}</tt> to avoid trouble with the backslash.
-#
-#   require "erb"
-#
-#   # Create template.
-#   template = %q{
-#     From:  James Edward Gray II <james@grayproductions.net>
-#     To:  <%= to %>
-#     Subject:  Addressing Needs
-#
-#     <%= to[/\w+/] %>:
-#
-#     Just wanted to send a quick note assuring that your needs are being
-#     addressed.
-#
-#     I want you to know that my team will keep working on the issues,
-#     especially:
-#
-#     <%# ignore numerous minor requests -- focus on priorities %>
-#     % priorities.each do |priority|
-#       * <%= priority %>
-#     % end
-#
-#     Thanks for your patience.

-# variables in the Product object can be resolved.

-# == Notes
-#
-# There are a variety of templating solutions available in various Ruby projects:
-# * ERB's big brother, eRuby, works the same but is written in C for speed;
-# * Amrita (smart at producing HTML/XML);
-# * cs/Template (written in C for speed);
-# * RDoc, distributed with Ruby, uses its own template engine, which can be reused elsewhere;
-# * and others; search the RAA.
-#
-# Rails, the web application framework, uses ERB to create views.

-# ERB::Compiler
-class ERB
-  # = ERB::Compiler
-  #
-  # Compiles ERB templates into Ruby code; the compiled code produces the
-  # template result when evaluated. ERB::Compiler provides hooks to define how
-  # generated output is handled.
-  #
-  # Internally ERB does something like this to generate the code returned by
-  # ERB#src:
-  #
-  #   compiler = ERB::Compiler.new('<>')
-  #   compiler.pre_cmd    = ["_erbout=''"]
-  #   compiler.put_cmd    = "_erbout.concat"
-  #   compiler.insert_cmd = "_erbout.concat"
-  #   compiler.post_cmd   = ["_erbout"]
-  #
-  #   code, enc = compiler.compile("Got <%= obj %>!\n")
-  #   puts code
-  #
-  # <i>Generates</i>:
-  #
-  #   #coding:UTF-8
-  #   _erbout=''; _erbout.concat "Got "; _erbout.concat(( obj ).to_s); _erbout.concat "!\n"; _erbout
-  #
-  # By default the output is sent to the print method.  For example:
-  #
-  #   compiler = ERB::Compiler.new('<>')
-  #   code, enc = compiler.compile("Got <%= obj %>!\n")
-  #   puts code
-  #
-  # <i>Generates</i>:
-  #
-  #   #coding:UTF-8
-  #   print "Got "; print(( obj ).to_s); print "!\n"
-  #
-  # == Evaluation
-  #
-  # The compiled code can be used in any context where the names in the code
-  # correctly resolve. Using the last example, each of these print 'Got It!'
-  #
-  # Evaluate using a variable:
-  #
-  #   obj = 'It'
-  #   eval code
-  #
-  # Evaluate using an input:
-  #
-  #   mod = Module.new
-  #   mod.module_eval %{
-  #     def get(obj)
-  #       #{code}
-  #     end
-  #   }
-  #   extend mod
-  #   get('It')
-  #
-  # Evaluate using an accessor:
-  #
-  #   klass = Class.new Object
-  #   klass.class_eval %{
-  #     attr_accessor :obj
-  #     def initialize(obj)
-  #       @obj = obj
-  #     end
-  #     def get_it
-  #       #{code}

-# ERB
-class ERB
-  #
-  # Constructs a new ERB object with the template specified in _str_.
-  #
-  # An ERB object works by building a chunk of Ruby code that will output
-  # the completed template when run. If _safe_level_ is set to a non-nil value,
-  # ERB code will be run in a separate thread with <b>$SAFE</b> set to the
-  # provided level.
-  #
-  # If _trim_mode_ is passed a String containing one or more of the following
-  # modifiers, ERB will adjust its code generation as listed:
-  #
-  #     %  enables Ruby code processing for lines beginning with %
-  #     <> omit newline for lines starting with <% and ending in %>
-  #     >  omit newline for lines ending in %>
-  #
-  # _eoutvar_ can be used to set the name of the variable ERB will build up
-  # its output in.  This is useful when you need to run multiple ERB
-  # templates through the same binding and/or when you want to control where
-  # output ends up.  Pass the name of the variable to be used inside a String.
-  #
-  # === Example
-  #
-  #  require "erb"
-  #
-  #  # build data class
-  #  class Listings
-  #    PRODUCT = { :name => "Chicken Fried Steak",
-  #                :desc => "A well messages pattie, breaded and fried.",

-  #    def initialize( product = "", price = "" )

-#       $Release Version: 1.1$
-#       $Revision$
-#       by Keiju ISHITSUKA(keiju@ishitsuka.com)
-#       original definition by delegator.rb
-#       Revised by Daniel J. Berger with suggestions from Florian Gross.
-#
-#       Documentation by James Edward Gray II and Gavin Sinclair
-#
-# == Introduction
-#
-# This library allows you delegate method calls to an object, on a method by
-# method basis.
-#
-# == Notes
-#
-# Be advised, RDoc will not detect delegated methods.
-#
-# <b>forwardable.rb provides single-method delegation via the
-# def_delegator() and def_delegators() methods.  For full-class
-# delegation via DelegateClass(), see delegate.rb.</b>
-#
-# == Examples
-#
-# === Forwardable
-#
-# Forwardable makes building a new class based on existing work, with a proper
-# interface, almost trivial.  We want to rely on what has come before obviously,
-# but with delegation we can take just the methods we need and even rename them
-# as appropriate.  In many cases this is preferable to inheritance, which gives
-# us the entire old interface, even if much of it isn't needed.
-#
-#   class Queue
-#     extend Forwardable
-#
-#     def initialize
-#       @q = [ ]    # prepare delegate object
-#     end
-#
-#     # setup preferred interface, enq() and deq()...
-#     def_delegator :@q, :push, :enq
-#     def_delegator :@q, :shift, :deq
-#
-#     # support some general Array methods that fit Queues well
-#     def_delegators :@q, :clear, :first, :push, :shift, :size
-#   end
-#
-#   q = Queue.new
-#   q.enq 1, 2, 3, 4, 5
-#   q.push 6
-#
-#   q.shift    # => 1
-#   while q.size > 0
-#     puts q.deq
-#   end
-#
-#   q.enq "Ruby", "Perl", "Python"
-#   puts q.first
-#   q.clear
-#   puts q.first
-#
-# <i>Prints:</i>
-#
-#   2
-#   3
-#   4
-#   5
-#   6
-#   Ruby
-#   nil
-#
-# SingleForwardable can be used to setup delegation at the object level as well.
-#
-#    printer = String.new
-#    printer.extend SingleForwardable        # prepare object for delegation
-#    printer.def_delegator "STDOUT", "puts"  # add delegation for STDOUT.puts()
-#    printer.puts "Howdy!"
-#
-# Also, SingleForwardable can be use to Class or Module.
-#
-#    module Facade
-#      extend SingleForwardable
-#      def_delegator :Implementation, :service
-#
-#      class Implementation
-#         def service...
-#      end
-#    end
-#
-# If you want to use both Forwardable and SingleForwardable, you can
-# use methods def_instance_delegator and def_single_delegator, etc.
-#
-# If the object isn't a Module and Class, You can too extend
-# Forwardable module.
-#    printer = String.new
-#    printer.extend Forwardable              # prepare object for delegation
-#    printer.def_delegator "STDOUT", "puts"  # add delegation for STDOUT.puts()
-#    printer.puts "Howdy!"
-#
-# <i>Prints:</i>
-#
-#    Howdy!
-
-#
-# The Forwardable module provides delegation of specified
-# methods to a designated object, using the methods #def_delegator
-# and #def_delegators.
-#
-# For example, say you have a class RecordCollection which
-# contains an array <tt>@records</tt>.  You could provide the lookup method
-# #record_number(), which simply calls #[] on the <tt>@records</tt>
-# array, like this:
-#
-#   class RecordCollection
-#     extend Forwardable
-#     def_delegator :@records, :[], :record_number
-#   end
-#
-# Further, if you wish to provide the methods #size, #<<, and #map,
-# all of which delegate to @records, this is how you can do it:
-#
-#   class RecordCollection
-#     # extend Forwardable, but we did that above
-#     def_delegators :@records, :size, :<<, :map
-#   end
-#   f = Foo.new
-#   f.printf ...
-#   f.gets
-#   f.content_at(1)
-#
-# Also see the example at forwardable.rb.

-  #
-  # <b>REQUIRE_ORDER</b> :
-  #
-  # Options are required to occur before non-options.
-  #
-  # Processing of options ends as soon as a word is encountered that has not
-  # been preceded by an appropriate option flag.
-  #
-  # For example, if -a and -b are options which do not take arguments,
-  # parsing command line arguments of '-a one -b two' would result in
-  # 'one', '-b', 'two' being left in ARGV, and only ('-a', '') being
-  # processed as an option/arg pair.
-  #
-  # This is the default ordering, if the environment variable
-  # POSIXLY_CORRECT is set. (This is for compatibility with GNU getopt_long.)
-  #
-  # <b>PERMUTE</b> :
-  #
-  # Options can occur anywhere in the command line parsed. This is the
-  # default behavior.
-  #
-  # Every sequence of words which can be interpreted as an option (with or
-  # without argument) is treated as an option; non-option words are skipped.
-  #
-  # For example, if -a does not require an argument and -b optionally takes
-  # an argument, parsing '-a one -b two three' would result in ('-a','') and
-  # ('-b', 'two') being processed as option/arg pairs, and 'one','three'
-  # being left in ARGV.
-  #
-  # If the ordering is set to PERMUTE but the environment variable
-  # POSIXLY_CORRECT is set, REQUIRE_ORDER is used instead. This is for
-  # compatibility with GNU getopt_long.
-  #
-  # <b>RETURN_IN_ORDER</b> :
-  #
-  # All words on the command line are processed as options. Words not
-  # preceded by a short or long option flag are passed as arguments
-  # with an option of '' (empty string).
-  #
-  # For example, if -a requires an argument but -b does not, a command line
-  # of '-a one -b two three' would result in option/arg pairs of ('-a', 'one')
-  # ('-b', ''), ('', 'two'), ('', 'three') being processed.

-# GServer implements a generic server, featuring thread pool management,
-# simple logging, and multi-server management.  See HttpServer in
-# <tt>xmlrpc/httpserver.rb</tt> in the Ruby standard library for an example of
-# GServer in action.
-#
-# Any kind of application-level server can be implemented using this class.
-# It accepts multiple simultaneous connections from clients, up to an optional
-# maximum number.  Several _services_ (i.e. one service per TCP port) can be
-# run simultaneously, and stopped at any time through the class method
-# <tt>GServer.stop(port)</tt>.  All the threading issues are handled, saving
-# you the effort.  All events are optionally logged, but you can provide your
-# own event handlers if you wish.
-#
-# == Example
-#
-# Using GServer is simple.  Below we implement a simple time server, run it,
-# query it, and shut it down.  Try this code in +irb+:
-#
-#   require 'gserver'
-#
-#   #
-#   # A server that returns the time in seconds since 1970.
-#   #
-#   class TimeServer < GServer
-#     def initialize(port=10001, *args)
-#       super(port, *args)
-#     end
-#     def serve(io)
-#       io.puts(Time.now.to_s)
-#     end
-#   end
-#
-#   # Run the server with logging enabled (it's a separate thread).
-#   server = TimeServer.new
-#   server.audit = true                  # Turn logging on.
-#   server.start
-#
-#   # *** Now point your browser to http://localhost:10001 to see it working ***
-#
-#   # See if it's still running.
-#   GServer.in_service?(10001)           # -> true
-#   server.stopped?                      # -> false
-#
-#   # Shut the server down gracefully.
-#   server.shutdown
-#
-#   # Alternatively, stop it immediately.
-#   GServer.stop(10001)
-#   # or, of course, "server.stop".
-#
-# All the business of accepting connections and exception handling is taken
-# care of.  All we have to do is implement the method that actually serves the
-# client.
-#
-# === Advanced
-#
-# As the example above shows, the way to use GServer is to subclass it to
-# create a specific server, overriding the +serve+ method.  You can override
-# other methods as well if you wish, perhaps to collect statistics, or emit
-# more detailed logging.
-#
-# * #connecting
-# * #disconnecting
-# * #starting
-# * #stopping
-#
-# The above methods are only called if auditing is enabled, via #audit=.
-#
-# You can also override #log and #error if, for example, you wish to use a
-# more sophisticated logging system.

-# Revision:: $Id$
-#
-# A simple system for logging messages.  See Logger for more documentation.
-
-require 'monitor'
-
-# == Description
-#
-# The Logger class provides a simple but sophisticated logging utility that
-# you can use to output messages.
-#
-# The messages have associated levels, such as +INFO+ or +ERROR+ that indicate
-# their importance.  You can then give the Logger a level, and only messages
-# at that level of higher will be printed.
-#
-# The levels are:
-#
-# +FATAL+:: an unhandleable error that results in a program crash
-# +ERROR+:: a handleable error condition
-# +WARN+::  a warning
-# +INFO+::  generic (useful) information about system operation
-# +DEBUG+:: low-level information for developers
-#
-# For instance, in a production system, you may have your Logger set to
-# +INFO+ or even +WARN+
-# When you are developing the system, however, you probably
-# want to know about the program's internal state, and would set the Logger to
-# +DEBUG+.
-#
-# *Note*: Logger does not escape or sanitize any messages passed to it.
-# Developers should be aware of when potentially malicious data (user-input)
-# is passed to Logger, and manually escape the untrusted data:
-#
-#   logger.info("User-input: #{input.dump}")
-#   logger.info("User-input: %p" % input)
-#
-# You can use #formatter= for escaping all data.
-#
-#   original_formatter = Logger::Formatter.new
-#   logger.formatter = proc { |severity, datetime, progname, msg|
-#     original_formatter.call(severity, datetime, progname, msg.dump)
-#   }
-#   logger.info(input)
-#
-# === Example
-#
-# This creates a logger to the standard output stream, with a level of +WARN+
-#
-#   log = Logger.new(STDOUT)
-#   log.level = Logger::WARN
-#
-#   log.debug("Created logger")
-#   log.info("Program started")
-#   log.warn("Nothing to do!")
-#
-#   begin
-#     File.each_line(path) do |line|
-#       unless line =~ /^(\w+) = (.*)$/
-#         log.error("Line in wrong format: #{line}")
-#       end
-#     end
-#   rescue => err
-#     log.fatal("Caught exception; exiting")
-#     log.fatal(err)
-#   end
-#
-# Because the Logger's level is set to +WARN+, only the warning, error, and
-# fatal messages are recorded.  The debug and info messages are silently
-# discarded.
-#
-# === Features
-#
-# There are several interesting features that Logger provides, like
-# auto-rolling of log files, setting the format of log messages, and
-# specifying a program name in conjunction with the message.  The next section
-# shows you how to achieve these things.
-#
-#
-# == HOWTOs
-#
-# === How to create a logger
-#
-# The options below give you various choices, in more or less increasing
-# complexity.
-#
-# 1. Create a logger which logs messages to STDERR/STDOUT.
-#
-#      logger = Logger.new(STDERR)
-#      logger = Logger.new(STDOUT)
-#
-# 2. Create a logger for the file which has the specified name.
-#
-#      logger = Logger.new('logfile.log')
-#
-# 3. Create a logger for the specified file.
-#
-#      file = File.open('foo.log', File::WRONLY | File::APPEND)
-#      # To create new (and to remove old) logfile, add File::CREAT like;
-#      #   file = open('foo.log', File::WRONLY | File::APPEND | File::CREAT)
-#      logger = Logger.new(file)
-#
-# 4. Create a logger which ages logfile once it reaches a certain size.  Leave
-#    10 "old log files" and each file is about 1,024,000 bytes.
-#
-#      logger = Logger.new('foo.log', 10, 1024000)
-#
-# 5. Create a logger which ages logfile daily/weekly/monthly.
-#
-#      logger = Logger.new('foo.log', 'daily')
-#      logger = Logger.new('foo.log', 'weekly')
-#      logger = Logger.new('foo.log', 'monthly')
-#
-# === How to log a message
-#
-# Notice the different methods (+fatal+, +error+, +info+) being used to log
-# messages of various levels?  Other methods in this family are +warn+ and
-# +debug+.  +add+ is used below to log a message of an arbitrary (perhaps
-# dynamic) level.
-#
-# 1. Message in block.
-#
-#      logger.fatal { "Argument 'foo' not given." }
-#
-# 2. Message as a string.
-#
-#      logger.error "Argument #{ @foo } mismatch."
-#
-# 3. With progname.
-#
-#      logger.info('initialize') { "Initializing..." }
-#
-# 4. With severity.
-#
-#      logger.add(Logger::FATAL) { 'Fatal error!' }
-#
-# The block form allows you to create potentially complex log messages,
-# but to delay their evaluation until and unless the message is
-# logged.  For example, if we have the following:
-#
-#     logger.debug { "This is a " + potentially + " expensive operation" }
-#
-# If the logger's level is +INFO+ or higher, no debug messages will be logged,
-# and the entire block will not even be evaluated.  Compare to this:
-#
-#     logger.debug("This is a " + potentially + " expensive operation")
-#
-# Here, the string concatenation is done every time, even if the log
-# level is not set to show the debug message.
-#
-# === How to close a logger
-#
-#      logger.close
-#
-# === Setting severity threshold
-#
-# 1. Original interface.
-#
-#      logger.sev_threshold = Logger::WARN
-#
-# 2. Log4r (somewhat) compatible interface.
-#
-#      logger.level = Logger::INFO
-#
-#      DEBUG < INFO < WARN < ERROR < FATAL < UNKNOWN
-#
-#
-# == Format
-#
-# Log messages are rendered in the output stream in a certain format by
-# default.  The default format and a sample are shown below:
-#
-# Log format:
-#   SeverityID, [Date Time mSec #pid] SeverityLabel -- ProgName: message
-#
-# Log sample:
-#   I, [Wed Mar 03 02:34:24 JST 1999 895701 #19074]  INFO -- Main: info.
-#
-# You may change the date and time format via #datetime_format=
-#
-#   logger.datetime_format = "%Y-%m-%d %H:%M:%S"
-#         # e.g. "2004-01-03 00:54:26"
-#
-# Or, you may change the overall format with #formatter= method.
-#
-#   logger.formatter = proc do |severity, datetime, progname, msg|
-#     "#{datetime}: #{msg}\n"
-#   end
-#   # e.g. "Thu Sep 22 08:51:08 GMT+9:00 2005: hello world"

-  #
-  # +logdev+::
-  #   The log device.  This is a filename (String) or IO object (typically
-  #   +STDOUT+, +STDERR+, or an open file).
-  # +shift_age+::
-  #   Number of old log files to keep, *or* frequency of rotation (+daily+,
-  #   +weekly+ or +monthly+).
-  # +shift_size+::
-  #   Maximum logfile size (only applies when +shift_age+ is a number).

-  #
-  #   Logger#add(severity, message = nil, progname = nil) { ... }
-  #
-  # === Args
-  #
-  # +severity+::
-  #   Severity.  Constants are defined in Logger namespace: +DEBUG+, +INFO+,
-  #   +WARN+, +ERROR+, +FATAL+, or +UNKNOWN+.
-  # +message+::
-  #   The log message.  A String or Exception.
-  # +progname+::
-  #   Program name string.  Can be omitted.  Treated as a message if no
-  #   +message+ and +block+ are given.
-  # +block+::
-  #   Can be omitted.  Called to get a message string if +message+ is nil.
-  #
-  # === Return
-  #
-  # +true+ if successful, +false+ otherwise.
-  #
-  # When the given severity is not high enough (for this particular logger), log
-  # no message, and return +true+.
-  #
-  # === Description
-  #
-  # Log a message if the given severity is high enough.  This is the generic
-  # logging method.  Users will be more inclined to use #debug, #info, #warn,
-  # #error, and #fatal.
-  #
-  # <b>Message format</b>: +message+ can be any object, but it has to be
-  # converted to a String in order to log it.  Generally, +inspect+ is used
-  # if the given object is not a String.
-  # A special case is an +Exception+ object, which will be printed in detail,
-  # including message, class, and backtrace.  See #msg2str for the
-  # implementation if required.
-  #
-  # === Bugs
-  #
-  # * Logfile is not locked.
-  # * Append open does not need to lock file.
-  # * If the OS which supports multi I/O, records possibly be mixed.

-  #                   unless the logger's level is sufficient
-  #                   to log the message.  This allows you to create
-  #                   potentially expensive logging messages that are
-  #                   only called when the logger is configured to show them.

-#
-# mathn is a library for changing the way Ruby does math.  If you need
-# more precise rounding with multiple division or exponentiation
-# operations, then mathn is the right tool.
-#
-# Without mathn:
-#
-#   3 / 2 => 1 # Integer
-#
-# With mathn:
-#
-#   3 / 2 => 3/2 # Rational
-#
-# mathn features late rounding and lacks truncation of intermediate results:
-#
-# Without mathn:
-#
-#   20 / 9 * 3 * 14 / 7 * 3 / 2 # => 18
-#
-# With mathn:
-#
-#   20 / 9 * 3 * 14 / 7 * 3 / 2 # => 20
-#
-#
-# When you require 'mathn', the libraries for Prime, CMath, Matrix and Vector
-# are also loaded.

-  # Adapted from JAMA: http://math.nist.gov/javanumerics/jama/

-  #
-  # For an m-by-n matrix A with m >= n, the LU decomposition is an m-by-n
-  # unit lower triangular matrix L, an n-by-n upper triangular matrix U,
-  # and a m-by-m permutation matrix P so that L*U = P*A.
-  # If m < n, then L is m-by-m and U is m-by-n.
-  #
-  # The LUP decomposition with pivoting always exists, even if the matrix is
-  # singular, so the constructor will never fail.  The primary use of the
-  # LU decomposition is in the solution of square systems of simultaneous
-  # linear equations.  This will fail if singular? returns true.

-
-== DESCRIPTION:
-
-minitest provides a complete suite of testing facilities supporting
-TDD, BDD, mocking, and benchmarking.
-
-minitest/unit is a small and incredibly fast unit testing framework.
-It provides a rich set of assertions to make your tests clean and
-readable.
-
-minitest/spec is a functionally complete spec engine. It hooks onto
-minitest/unit and seamlessly bridges test assertions over to spec
-expectations.
-
-minitest/benchmark is an awesome way to assert the performance of your
-algorithms in a repeatable manner. Now you can assert that your newb
-co-worker doesn't replace your linear algorithm with an exponential
-one!
-
-minitest/mock by Steven Baker, is a beautifully tiny mock object
-framework.
-
-minitest/pride shows pride in testing and adds coloring to your test
-output.
-
-minitest/unit is meant to have a clean implementation for language
-implementors that need a minimal set of methods to bootstrap a working
-test suite. For example, there is no magic involved for test-case
-discovery.
-
-== FEATURES/PROBLEMS:
-
-* minitest/autorun - the easy and explicit way to run all your tests.
-* minitest/unit - a very fast, simple, and clean test system.
-* minitest/spec - a very fast, simple, and clean spec system.
-* minitest/mock - a simple and clean mock system.
-* minitest/benchmark - an awesome way to assert your algorithm's performance.
-* minitest/pride - show your pride in testing!
-* Incredibly small and fast runner, but no bells and whistles.
-
-== RATIONALE:
-
-See design_rationale.rb to see how specs and tests work in minitest.
-
-== SYNOPSIS:
-
-Given that you'd like to test the following class:
-
-  class Meme
-    def i_can_has_cheezburger?
-      "OHAI!"
-    end
-
-    def will_it_blend?
-      "YES!"
-    end
-  end
-
-=== Unit tests
-
-  require 'minitest/autorun'
-
-  class TestMeme < MiniTest::Unit::TestCase
-    def setup
-      @meme = Meme.new
-    end
-
-    def test_that_kitty_can_eat
-      assert_equal "OHAI!", @meme.i_can_has_cheezburger?
-    end
-
-    def test_that_it_will_not_blend
-      refute_match /^no/i, @meme.will_it_blend?
-    end
-  end
-
-=== Specs
-
-  require 'minitest/autorun'
-
-  describe Meme do
-    before do
-      @meme = Meme.new
-    end
-
-    describe "when asked about cheeseburgers" do
-      it "must respond positively" do
-        @meme.i_can_has_cheezburger?.must_equal "OHAI!"
-      end
-    end
-
-    describe "when asked about blending possibilities" do
-      it "won't say no" do
-        @meme.will_it_blend?.wont_match /^no/i
-      end
-    end
-  end
-
-=== Benchmarks
-
-Add benchmarks to your regular unit tests. If the unit tests fail, the
-benchmarks won't run.
-
-  # optionally run benchmarks, good for CI-only work!
-  require 'minitest/benchmark' if ENV["BENCH"]
-
-  class TestMeme < MiniTest::Unit::TestCase
-    # Override self.bench_range or default range is [1, 10, 100, 1_000, 10_000]
-    def bench_my_algorithm
-      assert_performance_linear 0.9999 do |n| # n is a range value
-        n.times do
-          @obj.my_algorithm
-        end
-      end
-    end
-  end
-
-Or add them to your specs. If you make benchmarks optional, you'll
-need to wrap your benchmarks in a conditional since the methods won't
-be defined.
-
-  describe Meme do
-    if ENV["BENCH"] then
-      bench_performance_linear "my_algorithm", 0.9999 do |n|
-        100.times do
-          @obj.my_algorithm(n)
-        end
-      end
-    end
-  end
-
-outputs something like:
-
-  # Running benchmarks:
-
-  TestBlah	100	1000	10000
-  bench_my_algorithm	 0.006167	 0.079279	 0.786993
-  bench_other_algorithm	 0.061679	 0.792797	 7.869932
-
-Output is tab-delimited to make it easy to paste into a spreadsheet.
-
-=== Mocks
-
-  class MemeAsker
-    def initialize(meme)
-      @meme = meme
-    end
-
-    def ask(question)
-      method = question.tr(" ","_") + "?"
-      @meme.send(method)
-    end
-  end
-
-  require 'minitest/autorun'
-
-  describe MemeAsker do
-    before do
-      @meme = MiniTest::Mock.new
-      @meme_asker = MemeAsker.new @meme
-    end
-
-    describe "#ask" do
-      describe "when passed an unpunctuated question" do
-        it "should invoke the appropriate predicate method on the meme" do
-          @meme.expect :will_it_blend?, :return_value
-          @meme_asker.ask "will it blend"
-          @meme.verify
-        end
-      end
-    end
-  end
-
-=== Customizable Test Runner Types:
-
-MiniTest::Unit.runner=(runner) provides an easy way of creating custom
-test runners for specialized needs. Justin Weiss provides the
-following real-world example to create an alternative to regular
-fixture loading:
-
-  class MiniTestWithHooks::Unit < MiniTest::Unit
-    def before_suites
-    end
-
-    def after_suites
-    end
-
-    def _run_suites(suites, type)
-      begin
-        before_suites
-        super(suites, type)
-      ensure
-        after_suites
-      end
-    end
-
-    def _run_suite(suite, type)
-      begin
-        suite.before_suite
-        super(suite, type)
-      ensure
-        suite.after_suite
-      end
-    end
-  end
-
-  module MiniTestWithTransactions
-    class Unit < MiniTestWithHooks::Unit
-      include TestSetupHelper
-
-      def before_suites
-        super
-        setup_nested_transactions
-        # load any data we want available for all tests
-      end
-
-      def after_suites
-        teardown_nested_transactions
-        super
-      end
-    end
-  end
-
-  MiniTest::Unit.runner = MiniTestWithTransactions::Unit.new
-
-== REQUIREMENTS:
-
-* Ruby 1.8, maybe even 1.6 or lower. No magic is involved.
-
-== INSTALL:
-
-  sudo gem install minitest
-
-On 1.9, you already have it. To get newer candy you can still install
-the gem, but you'll need to activate the gem explicitly to use it:
-
-  require 'rubygems'
-  gem 'minitest' # ensures you're using the gem, and not the built in MT
-  require 'minitest/autorun'
-  
-  # ... usual testing stuffs ...

-# Generates the Makefile for your extension, passing along any options and

-#
-# The +target+ name should correspond the name of the global function name
-# defined within your C extension, minus the 'Init_'.  For example, if your
-# C extension is defined as 'Init_foo', then your target would simply be 'foo'.
-#
-# If any '/' characters are present in the target name, only the last name
-# is interpreted as the target name, and the rest are considered toplevel
-# directory names, and the generated Makefile will be altered accordingly to
-# follow that directory structure.
-#
-# For example, if you pass 'test/foo' as a target name, your extension will
-# be installed under the 'test' directory.  This means that in order to
-# load the file within a Ruby program later, that directory structure will
-# have to be followed, e.g. "require 'test/foo'".
-#
-# The +srcprefix+ should be used when your source files are not in the same
-# directory as your build script. This will not only eliminate the need for
-# you to manually copy the source files into the same directory as your build
-# script, but it also sets the proper +target_prefix+ in the generated
-# Makefile.
-#
-# Setting the +target_prefix+ will, in turn, install the generated binary in
-# a directory under your RbConfig::CONFIG['sitearchdir'] that mimics your local
-# filesystem when you run 'make install'.
-#
-# For example, given the following file tree:
-#
-#    ext/
-#       extconf.rb
-#       test/
-#          foo.c
-#
-# And given the following code:
-#
-#    create_makefile('test/foo', 'test')
-#
-# That will set the +target_prefix+ in the generated Makefile to 'test'. That,
-# in turn, will create the following file tree when installed via the
-# 'make install' command:
-#
-#    /path/to/ruby/sitearchdir/test/foo.so
-#
-# It is recommended that you use this approach to generate your makefiles,
-# instead of copying files around manually, because some third party
-# libraries may depend on the +target_prefix+ being set properly.
-#
-# The +srcprefix+ argument can be used to override the default source
-# directory, i.e. the current directory . It is included as part of the VPATH
-# and added to the list of INCFLAGS.

-require 'thread'

-#
-# In concurrent programming, a monitor is an object or module intended to be
-# used safely by more than one thread.  The defining characteristic of a
-# monitor is that its methods are executed with mutual exclusion.  That is, at
-# each point in time, at most one thread may be executing any of its methods.
-# This mutual exclusion greatly simplifies reasoning about the implementation
-# of monitors compared to reasoning about parallel code that updates a data
-# structure.
-#
-# You can read more about the general principles on the Wikipedia page for
-# Monitors[http://en.wikipedia.org/wiki/Monitor_%28synchronization%29]
-#
-# == Examples
-#
-# === Simple object.extend
-#
-#   require 'monitor.rb'
-#
-#   buf = []
-#   buf.extend(MonitorMixin)
-#   empty_cond = buf.new_cond
-#
-#   # consumer
-#   Thread.start do
-#     loop do
-#       buf.synchronize do
-#         empty_cond.wait_while { buf.empty? }
-#         print buf.shift
-#       end
-#     end
-#   end
-#
-#   # producer
-#   while line = ARGF.gets
-#     buf.synchronize do
-#       buf.push(line)
-#       empty_cond.signal
-#     end
-#   end
-#
-# The consumer thread waits for the producer thread to push a line to buf
-# while <tt>buf.empty?</tt>.  The producer thread (main thread) reads a
-# line from ARGF and pushes it into buf then calls <tt>empty_cond.signal</tt>
-# to notify the consumer thread of new data.
-#
-# === Simple Class include
-#
-#   require 'monitor'
-#
-#   class SynchronizedArray < Array
-#
-#     include MonitorMixin
-#
-#     def initialize(*args)
-#       super(*args)
-#     end
-#
-#     alias :old_shift :shift
-#     alias :old_unshift :unshift
-#
-#     def shift(n=1)
-#       self.synchronize do
-#         self.old_shift(n)
-#       end
-#     end
-#
-#     def unshift(item)
-#       self.synchronize do
-#         self.old_unshift(item)
-#       end
-#     end
-#
-#     # other methods ...
-#   end

-# This Class is implemented as subclass of Array which includes the
-# MonitorMixin module.

-# Documentation comments:
-#  - All documentation comes from Nutshell.
-#  - MonitorMixin.new_cond appears in the example, but is not documented in
-#    Nutshell.
-#  - All the internals (internal modules Accessible and Initializable, class
-#    ConditionVariable) appear in RDoc.  It might be good to hide them, by
-#    making them private, or marking them :nodoc:, etc.
-#  - RDoc doesn't recognise aliases, so we have mon_synchronize documented, but
-#    not synchronize.
-#  - mon_owner is in Nutshell, but appears as an accessor in a separate module
-#    here, so is hard/impossible to RDoc.  Some other useful accessors
-#    (mon_count and some queue stuff) are also in this module, and don't appear
-#    directly in the RDoc output.
-#  - in short, it may be worth changing the code layout in this file to make the
-#    documentation easier

-# Documentation by Gavin Sinclair, sourced from "Programming Ruby" (Hunt/Thomas)
-# and "Ruby In a Nutshell" (Matsumoto), used with permission.
-#
-# This library is distributed under the terms of the Ruby license.
-# You can freely distribute/modify this library.

-  # :stopdoc:
-  class FTPError < StandardError; end
-  class FTPReplyError < FTPError; end

-  #
-  # This class implements the File Transfer Protocol.  If you have used a
-  # command-line FTP program, and are familiar with the commands, you will be
-  # able to use this class easily.  Some extra features are included to take
-  # advantage of Ruby's style and strengths.
-  #
-  # == Example
-  #
-  #   require 'net/ftp'
-  #
-  # === Example 1
-  #
-  #   ftp = Net::FTP.new('ftp.netlab.co.jp')
-  #   ftp.login
-  #   files = ftp.chdir('pub/lang/ruby/contrib')
-  #   files = ftp.list('n*')
-  #   ftp.getbinaryfile('nif.rb-0.91.gz', 'nif.gz', 1024)
-  #   ftp.close
-  #
-  # === Example 2
-  #
-  #   Net::FTP.open('ftp.netlab.co.jp') do |ftp|
-  #     ftp.login
-  #     files = ftp.chdir('pub/lang/ruby/contrib')
-  #     files = ftp.list('n*')
-  #     ftp.getbinaryfile('nif.rb-0.91.gz', 'nif.gz', 1024)
-  #   end
-  #
-  # == Major Methods
-  #
-  # The following are the methods most likely to be useful to users:
-  # - FTP.open
-  # - #getbinaryfile
-  # - #gettextfile
-  # - #putbinaryfile
-  # - #puttextfile

-  # == An HTTP client API for Ruby.
-  #
-  # Net::HTTP provides a rich library which can be used to build HTTP
-  # user-agents.  For more details about HTTP see
-  # [RFC2616](http://www.ietf.org/rfc/rfc2616.txt)
-  #
-  # Net::HTTP is designed to work closely with URI.  URI::HTTP#host,
-  # URI::HTTP#port and URI::HTTP#request_uri are designed to work with
-  # Net::HTTP.
-  #
-  # If you are only performing a few GET requests you should try OpenURI.
-  #
-  # == Simple Examples
-  #
-  # All examples assume you have loaded Net::HTTP with:
-  #
-  #   require 'net/http'
-  #
-  # This will also require 'uri' so you don't need to require it separately.
-  #
-  # The Net::HTTP methods in the following section do not persist
-  # connections.  They are not recommended if you are performing many HTTP
-  # requests.
-  #
-  # === GET
-  #
-  #   Net::HTTP.get('example.com', '/index.html') # => String
-  #
-  # === GET by URI
-  #
-  #   uri = URI('http://example.com/index.html?count=10')
-  #   Net::HTTP.get(uri) # => String
-  #
-  # === GET with Dynamic Parameters
-  #
-  #   uri = URI('http://example.com/index.html')
-  #   params = { :limit => 10, :page => 3 }
-  #   uri.query = URI.encode_www_form(params)
-  #
-  #   res = Net::HTTP.get_response(uri)
-  #   puts res.body if res.is_a?(Net::HTTPSuccess)
-  #
-  # === POST
-  #
-  #   uri = URI('http://www.example.com/search.cgi')
-  #   res = Net::HTTP.post_form(uri, 'q' => 'ruby', 'max' => '50')
-  #   puts res.body
-  #
-  # === POST with Multiple Values
-  #
-  #   uri = URI('http://www.example.com/search.cgi')
-  #   res = Net::HTTP.post_form(uri, 'q' => ['ruby', 'perl'], 'max' => '50')
-  #   puts res.body
-  #
-  # == How to use Net::HTTP
-  #
-  # The following example code can be used as the basis of a HTTP user-agent
-  # which can perform a variety of request types using persistent
-  # connections.
-  #
-  #   uri = URI('http://example.com/some_path?query=string')
-  #
-  #   Net::HTTP.start(uri.host, uri.port) do |http|
-  #     request = Net::HTTP::Get.new uri.request_uri
-  #
-  #     response = http.request request # Net::HTTPResponse object
-  #   end
-  #
-  # Net::HTTP::start immediately creates a connection to an HTTP server which
-  # is kept open for the duration of the block.  The connection will remain
-  # open for multiple requests in the block if the server indicates it
-  # supports persistent connections.
-  #
-  # The request types Net::HTTP supports are listed below in the section "HTTP
-  # Request Classes".
-  #
-  # If you wish to re-use a connection across multiple HTTP requests without
-  # automatically closing it you can use ::new instead of ::start.  #request
-  # will automatically open a connection to the server if one is not currently
-  # open.  You can manually close the connection with #finish.
-  #
-  # === Response Data
-  #
-  #   uri = URI('http://example.com/index.html')
-  #   res = Net::HTTP.get_response(uri)
-  #
-  #   # Headers
-  #   res['Set-Cookie']            # => String
-  #   res.get_fields('set-cookie') # => Array
-  #   res.to_hash['set-cookie']    # => Array
-  #   puts "Headers: #{res.to_hash.inspect}"
-  #
-  #   # Status
-  #   puts res.code       # => '200'
-  #   puts res.message    # => 'OK'
-  #   puts res.class.name # => 'HTTPOK'
-  #
-  #   # Body
-  #   puts res.body if res.response_body_permitted?
-  #
-  # === Following Redirection
-  #
-  # Each Net::HTTPResponse object belongs to a class for its response code.
-  #
-  # For example, all 2XX responses are instances of a Net::HTTPSuccess
-  # subclass, a 3XX response is an instance of a Net::HTTPRedirection
-  # subclass and a 200 response is an instance of the Net::HTTPOK class.  For
-  # details of response classes, see the section "HTTP Response Classes"
-  # below.
-  #
-  # Using a case statement you can handle various types of responses properly:
-  #
-  #   def fetch(uri_str, limit = 10)
-  #     # You should choose a better exception.
-  #     raise ArgumentError, 'too many HTTP redirects' if limit == 0
-  #
-  #     response = Net::HTTP.get_response(URI(uri_str))
-  #
-  #     case response
-  #     when Net::HTTPSuccess then
-  #       response
-  #     when Net::HTTPRedirection then
-  #       location = response['location']
-  #       warn "redirected to #{location}"
-  #       fetch(location, limit - 1)
-  #     else
-  #       response.value
-  #     end
-  #   end
-  #
-  #   print fetch('http://www.ruby-lang.org')
-  #
-  # === POST
-  #
-  # A POST can be made using the Net::HTTP::Post request class.  This example
-  # creates a urlencoded POST body:
-  #
-  #   uri = URI('http://www.example.com/todo.cgi')
-  #   req = Net::HTTP::Post.new(uri.path)
-  #   req.set_form_data('from' => '2005-01-01', 'to' => '2005-03-31')
-  #
-  #   res = Net::HTTP.start(uri.hostname, uri.port) do |http|
-  #     http.request(req)
-  #   end
-  #
-  #   case res
-  #   when Net::HTTPSuccess, Net::HTTPRedirection
-  #     # OK
-  #   else
-  #     res.value
-  #   end
-  #
-  # At this time Net::HTTP does not support multipart/form-data.  To send
-  # multipart/form-data use Net::HTTPRequest#body= and
-  # Net::HTTPRequest#content_type=:
-  #
-  #   req = Net::HTTP::Post.new(uri.path)
-  #   req.body = multipart_data
-  #   req.content_type = 'multipart/form-data'
-  #
-  # Other requests that can contain a body such as PUT can be created in the
-  # same way using the corresponding request class (Net::HTTP::Put).
-  #
-  # === Setting Headers
-  #
-  # The following example performs a conditional GET using the
-  # If-Modified-Since header.  If the files has not been modified since the
-  # time in the header a Not Modified response will be returned.  See RFC 2616
-  # section 9.3 for further details.
-  #
-  #   uri = URI('http://example.com/cached_response')
-  #   file = File.stat 'cached_response'
-  #
-  #   req = Net::HTTP::Get.new(uri.request_uri)
-  #   req['If-Modified-Since'] = file.mtime.rfc2822
-  #
-  #   res = Net::HTTP.start(uri.hostname, uri.port) {|http|
-  #     http.request(req)
-  #   }
-  #
-  #   open 'cached_response', 'w' do |io|
-  #     io.write res.body
-  #   end if res.is_a?(Net::HTTPSuccess)
-  #
-  # === Basic Authentication
-  #
-  # Basic authentication is performed according to
-  # [RFC2617](http://www.ietf.org/rfc/rfc2617.txt)
-  #
-  #   uri = URI('http://example.com/index.html?key=value')
-  #
-  #   req = Net::HTTP::Get.new(uri.request_uri)
-  #   req.basic_auth 'user', 'pass'
-  #
-  #   res = Net::HTTP.start(uri.hostname, uri.port) {|http|
-  #     http.request(req)
-  #   }
-  #   puts res.body
-  #
-  # === Streaming Response Bodies
-  #
-  # By default Net::HTTP reads an entire response into memory.  If you are
-  # handling large files or wish to implement a progress bar you can instead
-  # stream the body directly to an IO.
-  #
-  #   uri = URI('http://example.com/large_file')
-  #
-  #   Net::HTTP.start(uri.host, uri.port) do |http|
-  #     request = Net::HTTP::Get.new uri.request_uri
-  #
-  #     http.request request do |response|
-  #       open 'large_file', 'w' do |io|
-  #         response.read_body do |chunk|
-  #           io.write chunk
-  #         end
-  #       end
-  #     end
-  #   end
-  #
-  # === HTTPS
-  #
-  # HTTPS is enabled for an HTTP connection by Net::HTTP#use_ssl=.
-  #
-  #   uri = URI('https://secure.example.com/some_path?query=string')
-  #
-  #   Net::HTTP.start(uri.host, uri.port,
-  #     :use_ssl => uri.scheme == 'https').start do |http|
-  #     request = Net::HTTP::Get.new uri.request_uri
-  #
-  #     response = http.request request # Net::HTTPResponse object
-  #   end
-  #
-  # In previous versions of ruby you would need to require 'net/https' to use
-  # HTTPS.  This is no longer true.
-  #
-  # === Proxies
-  #
-  # Net::HTTP::Proxy has the same methods as Net::HTTP but its instances always
-  # connect via the proxy instead of directly to the given host.
-  #
-  #   proxy_addr = 'your.proxy.host'
-  #   proxy_port = 8080
-  #
-  #   Net::HTTP::Proxy(proxy_addr, proxy_port).start('www.example.com') {|http|
-  #     # always connect to your.proxy.addr:8080
-  #   }
-  #
-  # Net::HTTP::Proxy returns a Net::HTTP instance when proxy_addr is nil so
-  # there is no need for conditional code.
-  #
-  # See Net::HTTP::Proxy for further details and examples such as proxies that
-  # require a username and password.
-  #
-  # == HTTP Request Classes
-  #
-  # Here is the HTTP request class hierarchy.
-  #
-  # * Net::HTTPRequest
-  #   * Net::HTTP::Get
-  #   * Net::HTTP::Head
-  #   * Net::HTTP::Post
-  #   * Net::HTTP::Put
-  #   * Net::HTTP::Proppatch

-
-  #
-  # Net::IMAP implements Internet Message Access Protocol (IMAP) client
-  # functionality.  The protocol is described in [IMAP].
-  #
-  # == IMAP Overview
-  #
-  # An IMAP client connects to a server, and then authenticates
-  # itself using either #authenticate() or #login().  Having
-  # authenticated itself, there is a range of commands
-  # available to it.  Most work with mailboxes, which may be
-  # arranged in an hierarchical namespace, and each of which
-  # contains zero or more messages.  How this is implemented on
-  # the server is implementation-dependent; on a UNIX server, it
-  # will frequently be implemented as a files in mailbox format
-  # within a hierarchy of directories.
-  #
-  # To work on the messages within a mailbox, the client must
-  # first select that mailbox, using either #select() or (for
-  # read-only access) #examine().  Once the client has successfully
-  # selected a mailbox, they enter _selected_ state, and that
-  # mailbox becomes the _current_ mailbox, on which mail-item
-  # related commands implicitly operate.
-  #
-  # Messages have two sorts of identifiers: message sequence
-  # numbers, and UIDs.
-  #
-  # Message sequence numbers number messages within a mail box
-  # from 1 up to the number of items in the mail box.  If new
-  # message arrives during a session, it receives a sequence
-  # number equal to the new size of the mail box.  If messages
-  # are expunged from the mailbox, remaining messages have their
-  # sequence numbers "shuffled down" to fill the gaps.
-  #
-  # UIDs, on the other hand, are permanently guaranteed not to
-  # identify another message within the same mailbox, even if
-  # the existing message is deleted.  UIDs are required to
-  # be assigned in ascending (but not necessarily sequential)
-  # order within a mailbox; this means that if a non-IMAP client
-  # rearranges the order of mailitems within a mailbox, the
-  # UIDs have to be reassigned.  An IMAP client cannot thus
-  # rearrange message orders.
-  #
-  # == Examples of Usage
-  #
-  # === List sender and subject of all recent messages in the default mailbox
-  #
-  #   imap = Net::IMAP.new('mail.example.com')
-  #   imap.authenticate('LOGIN', 'joe_user', 'joes_password')
-  #   imap.examine('INBOX')
-  #   imap.search(["RECENT"]).each do |message_id|
-  #     envelope = imap.fetch(message_id, "ENVELOPE")[0].attr["ENVELOPE"]
-  #     puts "#{envelope.from[0].name}: \t#{envelope.subject}"
-  #   end
-  #
-  # === Move all messages from April 2003 from "Mail/sent-mail" to "Mail/sent-apr03"
-  #
-  #   imap = Net::IMAP.new('mail.example.com')
-  #   imap.authenticate('LOGIN', 'joe_user', 'joes_password')
-  #   imap.select('Mail/sent-mail')
-  #   if not imap.list('Mail/', 'sent-apr03')
-  #     imap.create('Mail/sent-apr03')
-  #   end
-  #   imap.search(["BEFORE", "30-Apr-2003", "SINCE", "1-Apr-2003"]).each do |message_id|
-  #     imap.copy(message_id, "Mail/sent-apr03")
-  #     imap.store(message_id, "+FLAGS", [:Deleted])
-  #   end
-  #   imap.expunge
-  #
-  # == Thread Safety
-  #
-  # Net::IMAP supports concurrent threads. For example,
-  #
-  #   imap = Net::IMAP.new("imap.foo.net", "imap2")
-  #   imap.authenticate("cram-md5", "bar", "password")
-  #   imap.select("inbox")
-  #   fetch_thread = Thread.start { imap.fetch(1..-1, "UID") }
-  #   search_result = imap.search(["BODY", "hello"])
-  #   fetch_result = fetch_thread.value
-  #   imap.disconnect
-  #
-  # This script invokes the FETCH command and the SEARCH command concurrently.
-  #
-  # == Errors
-  #
-  # An IMAP server can send three different types of responses to indicate
-  # failure:
-  #
-  # NO:: the attempted command could not be successfully completed.  For
-  #      instance, the username/password used for logging in are incorrect;
-  #      the selected mailbox does not exists; etc.
-  #
-  # BAD:: the request from the client does not follow the server's
-  #       understanding of the IMAP protocol.  This includes attempting
-  #       commands from the wrong client state; for instance, attempting
-  #       to perform a SEARCH command without having SELECTed a current
-  #       mailbox.  It can also signal an internal server
-  #       failure (such as a disk crash) has occurred.
-  #
-  # BYE:: the server is saying goodbye.  This can be part of a normal
-  #       logout sequence, and can be used as part of a login sequence
-  #       to indicate that the server is (for some reason) unwilling
-  #       to accept our connection.  As a response to any other command,
-  #       it indicates either that the server is shutting down, or that
-  #       the server is timing out the client connection due to inactivity.
-  #
-  # These three error response are represented by the errors
-  # Net::IMAP::NoResponseError, Net::IMAP::BadResponseError, and
-  # Net::IMAP::ByeResponseError, all of which are subclasses of
-  # Net::IMAP::ResponseError.  Essentially, all methods that involve
-  # sending a request to the server can generate one of these errors.
-  # Only the most pertinent instances have been documented below.
-  #
-  # Because the IMAP class uses Sockets for communication, its methods
-  # are also susceptible to the various errors that can occur when
-  # working with sockets.  These are generally represented as
-  # Errno errors.  For instance, any method that involves sending a
-  # request to the server and/or receiving a response from it could
-  # raise an Errno::EPIPE error if the network connection unexpectedly
-  # goes down.  See the socket(7), ip(7), tcp(7), socket(2), connect(2),
-  # and associated man pages.
-  #
-  # Finally, a Net::IMAP::DataFormatError is thrown if low-level data
-  # is found to be in an incorrect format (for instance, when converting
-  # between UTF-8 and UTF-16), and Net::IMAP::ResponseParseError is
-  # thrown if a server response is non-parseable.

-  # = Net::POP3
-  #
-  # == What is This Library?
-  #
-  # This library provides functionality for retrieving
-  # email via POP3, the Post Office Protocol version 3. For details
-  # of POP3, see [RFC1939] (http://www.ietf.org/rfc/rfc1939.txt).
-  #
-  # == Examples
-  #
-  # === Retrieving Messages
-  #
-  # This example retrieves messages from the server and deletes them
-  # on the server.
-  #
-  # Messages are written to files named 'inbox/1', 'inbox/2', ....
-  # Replace 'pop.example.com' with your POP3 server address, and
-  # 'YourAccount' and 'YourPassword' with the appropriate account
-  # details.
-  #
-  #     require 'net/pop'
-  #
-  #     pop = Net::POP3.new('pop.example.com')
-  #     pop.start('YourAccount', 'YourPassword')             # (1)
-  #     if pop.mails.empty?
-  #       puts 'No mail.'
-  #     else
-  #       i = 0
-  #       pop.each_mail do |m|   # or "pop.mails.each ..."   # (2)
-  #         File.open("inbox/#{i}", 'w') do |f|
-  #           f.write m.pop
-  #         end
-  #         m.delete
-  #         i += 1
-  #       end
-  #       puts "#{pop.mails.size} mails popped."
-  #     end
-  #     pop.finish                                           # (3)
-  #
-  # 1. Call Net::POP3#start and start POP session.
-  # 2. Access messages by using POP3#each_mail and/or POP3#mails.
-  # 3. Close POP session by calling POP3#finish or use the block form of #start.
-  #
-  # === Shortened Code
-  #
-  # The example above is very verbose. You can shorten the code by using
-  # some utility methods. First, the block form of Net::POP3.start can
-  # be used instead of POP3.new, POP3#start and POP3#finish.
-  #
-  #     require 'net/pop'
-  #
-  #     Net::POP3.start('pop.example.com', 110,
-  #                     'YourAccount', 'YourPassword') do |pop|
-  #       if pop.mails.empty?
-  #         puts 'No mail.'
-  #       else
-  #         i = 0
-  #         pop.each_mail do |m|   # or "pop.mails.each ..."
-  #           File.open("inbox/#{i}", 'w') do |f|
-  #             f.write m.pop
-  #           end
-  #           m.delete
-  #           i += 1
-  #         end
-  #         puts "#{pop.mails.size} mails popped."
-  #       end
-  #     end
-  #
-  # POP3#delete_all is an alternative for #each_mail and #delete.
-  #
-  #     require 'net/pop'
-  #
-  #     Net::POP3.start('pop.example.com', 110,
-  #                     'YourAccount', 'YourPassword') do |pop|
-  #       if pop.mails.empty?
-  #         puts 'No mail.'
-  #       else
-  #         i = 1
-  #         pop.delete_all do |m|
-  #           File.open("inbox/#{i}", 'w') do |f|
-  #             f.write m.pop
-  #           end
-  #           i += 1
-  #         end
-  #       end
-  #     end
-  #
-  # And here is an even shorter example.
-  #
-  #     require 'net/pop'
-  #
-  #     i = 0
-  #     Net::POP3.delete_all('pop.example.com', 110,
-  #                          'YourAccount', 'YourPassword') do |m|
-  #       File.open("inbox/#{i}", 'w') do |f|
-  #         f.write m.pop
-  #       end
-  #       i += 1
-  #     end
-  #
-  # === Memory Space Issues
-  #
-  # All the examples above get each message as one big string.
-  # This example avoids this.
-  #
-  #     require 'net/pop'
-  #
-  #     i = 1
-  #     Net::POP3.delete_all('pop.example.com', 110,
-  #                          'YourAccount', 'YourPassword') do |m|
-  #       File.open("inbox/#{i}", 'w') do |f|
-  #         m.pop do |chunk|    # get a message little by little.
-  #           f.write chunk
-  #         end
-  #         i += 1
-  #       end
-  #     end
-  #
-  # === Using APOP
-  #
-  # The net/pop library supports APOP authentication.
-  # To use APOP, use the Net::APOP class instead of the Net::POP3 class.
-  # You can use the utility method, Net::POP3.APOP(). For example:
-  #
-  #     require 'net/pop'
-  #
-  #     # Use APOP authentication if $isapop == true
-  #     pop = Net::POP3.APOP($is_apop).new('apop.example.com', 110)
-  #     pop.start(YourAccount', 'YourPassword') do |pop|
-  #       # Rest of the code is the same.
-  #     end
-  #
-  # === Fetch Only Selected Mail Using 'UIDL' POP Command
-  #
-  # If your POP server provides UIDL functionality,
-  # you can grab only selected mails from the POP server.
-  # e.g.
-  #
-  #     def need_pop?( id )
-  #       # determine if we need pop this mail...
-  #     end
-  #
-  #     Net::POP3.start('pop.example.com', 110,
-  #                     'Your account', 'Your password') do |pop|
-  #       pop.mails.select { |m| need_pop?(m.unique_id) }.each do |m|
-  #         do_something(m.pop)
-  #       end
-  #     end
-  #
-  # The POPMail#unique_id() method returns the unique-id of the message as a
-  # String. Normally the unique-id is a hash of the message.
-  #
-  class POP3 < Protocol
-
-    # svn revision of this library
-    Revision = %q$Revision$.split[1]
-
-    #
-    # Class Parameters
-    #
-
-    # returns the port for POP3
-    def POP3.default_port
-      default_pop3_port()
-    end
-
-    # The default port for POP3 connections, port 110
-    def POP3.default_pop3_port

-
-    #
-    # Utilities
-    #
-
-    # Returns the APOP class if +isapop+ is true; otherwise, returns
-    # the POP class.  For example:
-    #
-    #     # Example 1
-    #     pop = Net::POP3::APOP($is_apop).new(addr, port)
-    #
-    #     # Example 2
-    #     Net::POP3::APOP($is_apop).start(addr, port) do |pop|
-    #       ....
-    #     end
-    #
-    def POP3.APOP(isapop)
-      isapop ? APOP : POP3
-    end
-
-    # Starts a POP3 session and iterates over each POPMail object,
-    # yielding it to the +block+.
-    # This method is equivalent to:
-    #
-    #     Net::POP3.start(address, port, account, password) do |pop|
-    #       pop.each_mail do |m|
-    #         yield m
-    #       end
-    #     end
-    #
-    # This method raises a POPAuthenticationError if authentication fails.
-    #
-    # === Example
-    #
-    #     Net::POP3.foreach('pop.example.com', 110,
-    #                       'YourAccount', 'YourPassword') do |m|
-    #       file.write m.pop
-    #       m.delete if $DELETE
-    #     end

-                     account = nil, password = nil,
-                     isapop = false, &block)  # :yields: message
-      start(address, port, account, password, isapop) {|pop|
-        pop.each_mail(&block)
-      }
-    end
-
-    # Starts a POP3 session and deletes all messages on the server.
-    # If a block is given, each POPMail object is yielded to it before
-    # being deleted.
-    #
-    # This method raises a POPAuthenticationError if authentication fails.
-    #
-    # === Example
-    #
-    #     Net::POP3.delete_all('pop.example.com', 110,
-    #                          'YourAccount', 'YourPassword') do |m|
-    #       file.write m.pop
-    #     end
-    #
-    def POP3.delete_all(address, port = nil,
-                        account = nil, password = nil,
-                        isapop = false, &block)
-      start(address, port, account, password, isapop) {|pop|
-        pop.delete_all(&block)
-      }
-    end
-
-    # Opens a POP3 session, attempts authentication, and quits.
-    #
-    # This method raises POPAuthenticationError if authentication fails.
-    #
-    # === Example: normal POP3
-    #
-    #     Net::POP3.auth_only('pop.example.com', 110,
-    #                         'YourAccount', 'YourPassword')
-    #
-    # === Example: APOP
-    #
-    #     Net::POP3.auth_only('pop.example.com', 110,
-    #                         'YourAccount', 'YourPassword', true)

-  # == What is This Library?
-  #
-  # This library provides functionality to send internet
-  # mail via SMTP, the Simple Mail Transfer Protocol. For details of
-  # SMTP itself, see [RFC2821] (http://www.ietf.org/rfc/rfc2821.txt).
-  #
-  # == What is This Library NOT?
-  #
-  # This library does NOT provide functions to compose internet mails.
-  # You must create them by yourself. If you want better mail support,
-  # try RubyMail or TMail. You can get both libraries from RAA.
-  # (http://www.ruby-lang.org/en/raa.html)
-  #
-  # FYI: the official documentation on internet mail is: [RFC2822] (http://www.ietf.org/rfc/rfc2822.txt).
-  #
-  # == Examples
-  #
-  # === Sending Messages
-  #
-  # You must open a connection to an SMTP server before sending messages.
-  # The first argument is the address of your SMTP server, and the second
-  # argument is the port number. Using SMTP.start with a block is the simplest
-  # way to do this. This way, the SMTP connection is closed automatically
-  # after the block is executed.
-  #
-  #     require 'net/smtp'
-  #     Net::SMTP.start('your.smtp.server', 25) do |smtp|
-  #       # Use the SMTP object smtp only in this block.
-  #     end
-  #
-  # Replace 'your.smtp.server' with your SMTP server. Normally
-  # your system manager or internet provider supplies a server
-  # for you.
-  #
-  # Then you can send messages.
-  #
-  #     msgstr = <<END_OF_MESSAGE
-  #     From: Your Name <your@mail.address>
-  #     To: Destination Address <someone@example.com>
-  #     Subject: test message
-  #     Date: Sat, 23 Jun 2001 16:26:43 +0900
-  #     Message-Id: <unique.message.id.string@example.com>
-  #
-  #     This is a test message.
-  #     END_OF_MESSAGE
-  #
-  #     require 'net/smtp'
-  #     Net::SMTP.start('your.smtp.server', 25) do |smtp|
-  #       smtp.send_message msgstr,
-  #                         'your@mail.address',
-  #                         'his_address@example.com'
-  #     end
-  #
-  # === Closing the Session
-  #
-  # You MUST close the SMTP session after sending messages, by calling
-  # the #finish method:
-  #
-  #     # using SMTP#finish
-  #     smtp = Net::SMTP.start('your.smtp.server', 25)
-  #     smtp.send_message msgstr, 'from@address', 'to@address'
-  #     smtp.finish
-  #
-  # You can also use the block form of SMTP.start/SMTP#start.  This closes
-  # the SMTP session automatically:
-  #
-  #     # using block form of SMTP.start
-  #     Net::SMTP.start('your.smtp.server', 25) do |smtp|
-  #       smtp.send_message msgstr, 'from@address', 'to@address'
-  #     end
-  #
-  # I strongly recommend this scheme.  This form is simpler and more robust.
-  #
-  # === HELO domain
-  #
-  # In almost all situations, you must provide a third argument
-  # to SMTP.start/SMTP#start. This is the domain name which you are on
-  # (the host to send mail from). It is called the "HELO domain".
-  # The SMTP server will judge whether it should send or reject
-  # the SMTP session by inspecting the HELO domain.
-  #
-  #     Net::SMTP.start('your.smtp.server', 25,
-  #                     'mail.from.domain') { |smtp| ... }
-  #
-  # === SMTP Authentication
-  #
-  # The Net::SMTP class supports three authentication schemes;
-  # PLAIN, LOGIN and CRAM MD5.  (SMTP Authentication: [RFC2554])
-  # To use SMTP authentication, pass extra arguments to
-  # SMTP.start/SMTP#start.
-  #
-  #     # PLAIN
-  #     Net::SMTP.start('your.smtp.server', 25, 'mail.from.domain',
-  #                     'Your Account', 'Your Password', :plain)
-  #     # LOGIN
-  #     Net::SMTP.start('your.smtp.server', 25, 'mail.from.domain',
-  #                     'Your Account', 'Your Password', :login)
-  #
-  #     # CRAM MD5
-  #     Net::SMTP.start('your.smtp.server', 25, 'mail.from.domain',
-  #                     'Your Account', 'Your Password', :cram_md5)

-    #
-    #   # example
-    #   smtp = Net::SMTP.new(addr, port)
-    #   smtp.set_debug_output $stderr
-    #   smtp.start do |smtp|

-    # SMTP session control

-
-    #
-    # Creates a new Net::SMTP object and connects to the server.
-    #
-    # This method is equivalent to:
-    #
-    #   Net::SMTP.new(address, port).start(helo_domain, account, password, authtype)
-    #
-    # === Example
-    #
-    #     Net::SMTP.start('your.smtp.server') do |smtp|
-    #       smtp.send_message msgstr, 'from@example.com', ['dest@example.com']
-    #     end
-    #
-    # === Block Usage
-    #
-    # If called with a block, the newly-opened Net::SMTP object is yielded
-    # to the block, and automatically closed when the block finishes.  If called
-    # without a block, the newly-opened Net::SMTP object is returned to
-    # the caller, and it is the caller's responsibility to close it when
-    # finished.
-    #
-    # === Parameters
-    #
-    # +address+ is the hostname or ip address of your smtp server.
-    #
-    # +port+ is the port to connect to; it defaults to port 25.
-    #
-    # +helo+ is the _HELO_ _domain_ provided by the client to the
-    # server (see overview comments); it defaults to 'localhost'.
-    #
-    # The remaining arguments are used for SMTP authentication, if required
-    # or desired.  +user+ is the account name; +secret+ is your password
-    # or other authentication token; and +authtype+ is the authentication
-    # type, one of :plain, :login, or :cram_md5.  See the discussion of
-    # SMTP Authentication in the overview notes.
-    #
-    # === Errors
-    #
-    # This method may raise:
-    #
-    # * Net::SMTPAuthenticationError
-    # * Net::SMTPServerBusy
-    # * Net::SMTPSyntaxError
-    # * Net::SMTPFatalError
-    # * Net::SMTPUnknownError
-    # * IOError
-    # * TimeoutError

-      new(address, port).start(helo, user, secret, authtype, &block)

-    def started?
-      @started
-    end
-
-    #
-    # Opens a TCP connection and starts the SMTP session.
-    #
-    # === Parameters
-    #
-    # +helo+ is the _HELO_ _domain_ that you'll dispatch mails from; see
-    # the discussion in the overview notes.
-    #
-    # If both of +user+ and +secret+ are given, SMTP authentication
-    # will be attempted using the AUTH command.  +authtype+ specifies
-    # the type of authentication to attempt; it must be one of
-    # :login, :plain, and :cram_md5.  See the notes on SMTP Authentication
-    # in the overview.
-    #
-    # === Block Usage
-    #
-    # When this methods is called with a block, the newly-started SMTP
-    # object is yielded to the block, and automatically closed after
-    # the block call finishes.  Otherwise, it is the caller's
-    # responsibility to close the session when finished.
-    #
-    # === Example
-    #
-    # This is very similar to the class method SMTP.start.
-    #
-    #     require 'net/smtp'
-    #     smtp = Net::SMTP.new('smtp.mail.server', 25)
-    #     smtp.start(helo_domain, account, password, authtype) do |smtp|
-    #       smtp.send_message msgstr, 'from@example.com', ['dest@example.com']
-    #     end
-    #
-    # The primary use of this method (as opposed to SMTP.start)
-    # is probably to set debugging (#set_debug_output) or ESMTP
-    # (#esmtp=), which must be done before the session is
-    # started.
-    #
-    # === Errors
-    #
-    # If session has already been started, an IOError will be raised.
-    #
-    # This method may raise:
-    #
-    # * Net::SMTPAuthenticationError
-    # * Net::SMTPServerBusy
-    # * Net::SMTPSyntaxError
-    # * Net::SMTPFatalError
-    # * Net::SMTPUnknownError

-  #
-  # == Net::Telnet
-  #
-  # Provides telnet client functionality.
-  #
-  # This class also has, through delegation, all the methods of a
-  # socket object (by default, a +TCPSocket+, but can be set by the
-  # +Proxy+ option to <tt>new()</tt>).  This provides methods such as
-  # <tt>close()</tt> to end the session and <tt>sysread()</tt> to read
-  # data directly from the host, instead of via the <tt>waitfor()</tt>
-  # mechanism.  Note that if you do use <tt>sysread()</tt> directly
-  # when in telnet mode, you should probably pass the output through
-  # <tt>preprocess()</tt> to extract telnet command sequences.
-  #
-  # == Overview
-  #
-  # The telnet protocol allows a client to login remotely to a user
-  # account on a server and execute commands via a shell.  The equivalent
-  # is done by creating a Net::Telnet class with the +Host+ option
-  # set to your host, calling #login() with your user and password,
-  # issuing one or more #cmd() calls, and then calling #close()
-  # to end the session.  The #waitfor(), #print(), #puts(), and
-  # #write() methods, which #cmd() is implemented on top of, are
-  # only needed if you are doing something more complicated.
-  #
-  # A Net::Telnet object can also be used to connect to non-telnet
-  # services, such as SMTP or HTTP.  In this case, you normally
-  # want to provide the +Port+ option to specify the port to
-  # connect to, and set the +Telnetmode+ option to false to prevent
-  # the client from attempting to interpret telnet command sequences.
-  # Generally, #login() will not work with other protocols, and you
-  # have to handle authentication yourself.
-  #
-  # For some protocols, it will be possible to specify the +Prompt+
-  # option once when you create the Telnet object and use #cmd() calls;
-  # for others, you will have to specify the response sequence to
-  # look for as the Match option to every #cmd() call, or call
-  # #puts() and #waitfor() directly; for yet others, you will have
-  # to use #sysread() instead of #waitfor() and parse server
-  # responses yourself.
-  #
-  # It is worth noting that when you create a new Net::Telnet object,
-  # you can supply a proxy IO channel via the Proxy option.  This
-  # can be used to attach the Telnet object to other Telnet objects,
-  # to already open sockets, or to any read-write IO object.  This
-  # can be useful, for instance, for setting up a test fixture for
-  # unit testing.
-  #
-  # == Examples
-  #
-  # === Log in and send a command, echoing all output to stdout
-  #
-  #   localhost = Net::Telnet::new("Host" => "localhost",
-  #                                "Timeout" => 10,
-  #                                "Prompt" => /[$%#>] \z/n)
-  #   localhost.login("username", "password") { |c| print c }
-  #   localhost.cmd("command") { |c| print c }
-  #   localhost.close
-  #
-  #
-  # === Check a POP server to see if you have mail
-  #
-  #   pop = Net::Telnet::new("Host" => "your_destination_host_here",
-  #                          "Port" => 110,
-  #                          "Telnetmode" => false,
-  #                          "Prompt" => /^\+OK/n)
-  #   pop.cmd("user " + "your_username_here") { |c| print c }
-  #   pop.cmd("pass " + "your_password_here") { |c| print c }
-  #   pop.cmd("list") { |c| print c }
-  #

-    #            "Dump_log"   => "dump_log",   # default: nil (no output)
-    #            "Prompt"     => /[$%#>] \z/n, # default: /[$%#>] \z/n
-    #            "Telnetmode" => true,         # default: true
-    #            "Timeout"    => 10,           # default: 10
-    #              # if ignore timeout then set "Timeout" to false.
-    #            "Waittime"   => 0,            # default: 0
-    #            "Proxy"      => proxy         # default: nil
-    #                            # proxy is Net::Telnet or IO object
-    #          )
-    #
-    # The options have the following meanings:
-    #
-    # Host:: the hostname or IP address of the host to connect to, as a String.
-    #        Defaults to "localhost".
-    #
-    # Port:: the port to connect to.  Defaults to 23.
-    #
-    # Binmode:: if false (the default), newline substitution is performed.
-    #           Outgoing LF is
-    #           converted to CRLF, and incoming CRLF is converted to LF.  If
-    #           true, this substitution is not performed.  This value can
-    #           also be set with the #binmode() method.  The
-    #           outgoing conversion only applies to the #puts() and #print()
-    #           methods, not the #write() method.  The precise nature of
-    #           the newline conversion is also affected by the telnet options
-    #           SGA and BIN.
-    #
-    # Output_log:: the name of the file to write connection status messages
-    #              and all received traffic to.  In the case of a proper
-    #              Telnet session, this will include the client input as
-    #              echoed by the host; otherwise, it only includes server
-    #              responses.  Output is appended verbatim to this file.
-    #              By default, no output log is kept.
-    #
-    # Dump_log:: as for Output_log, except that output is written in hexdump
-    #            format (16 bytes per line as hex pairs, followed by their
-    #            printable equivalent), with connection status messages
-    #            preceded by '#', sent traffic preceded by '>', and
-    #            received traffic preceded by '<'.  By default, not dump log
-    #            is kept.
-    #
-    # Prompt:: a regular expression matching the host's command-line prompt
-    #          sequence.  This is needed by the Telnet class to determine
-    #          when the output from a command has finished and the host is
-    #          ready to receive a new command.  By default, this regular
-    #          expression is /[$%#>] \z/n.
-    #
-    # Telnetmode:: a boolean value, true by default.  In telnet mode,
-    #              traffic received from the host is parsed for special
-    #              command sequences, and these sequences are escaped
-    #              in outgoing traffic sent using #puts() or #print()
-    #              (but not #write()).  If you are using the Net::Telnet
-    #              object to connect to a non-telnet service (such as
-    #              SMTP or POP), this should be set to "false" to prevent
-    #              undesired data corruption.  This value can also be set
-    #              by the #telnetmode() method.
-    #
-    # Timeout:: the number of seconds to wait before timing out both the
-    #           initial attempt to connect to host (in this constructor),
-    #           and all attempts to read data from the host (in #waitfor(),
-    #           #cmd(), and #login()).  Exceeding this timeout causes a

-    #           Errno::ETIMEDOUT error (but generally only after a few

-#
-# Implementation of the _Observer_ object-oriented design pattern.  The
-# following documentation is copied, with modifications, from "Programming
-# Ruby", by Hunt and Thomas; http://www.rubycentral.com/book/lib_patterns.html.
-#
-# See Observable for more info.
-
-# The Observer pattern (also known as publish/subscribe) provides a simple
-# mechanism for one object to inform a set of interested third-party objects
-# when its state changes.
-#
-# == Mechanism
-#
-# The notifying class mixes in the +Observable+
-# module, which provides the methods for managing the associated observer
-# objects.
-#
-# The observers must implement a method called +update+ to receive
-# notifications.
-#
-# The observable object must:
-# * assert that it has +#changed+
-# * call +#notify_observers+
-#
-# === Example
-#
-# The following example demonstrates this nicely.  A +Ticker+, when run,
-# continually receives the stock +Price+ for its <tt>@symbol</tt>.  A +Warner+
-# is a general observer of the price, and two warners are demonstrated, a
-# +WarnLow+ and a +WarnHigh+, which print a warning if the price is below or
-# above their set limits, respectively.
-#
-# The +update+ callback allows the warners to run without being explicitly
-# called.  The system is set up with the +Ticker+ and several observers, and the
-# observers do their duty without the top-level code having to interfere.
-#
-# Note that the contract between publisher and subscriber (observable and
-# observer) is not declared or enforced.  The +Ticker+ publishes a time and a
-# price, and the warners receive that.  But if you don't ensure that your
-# contracts are correct, nothing else can warn you.
-#

-    #    :read_timeout=>10      (10 second)
-    #
-    #  :read_timeout option specifies a timeout of read for http connections.

-# == OptionParser
-#
-# === Introduction
-#
-# OptionParser is a class for command-line option analysis.  It is much more
-# advanced, yet also easier to use, than GetoptLong, and is a more Ruby-oriented
-# solution.
-#
-# === Features
-#
-# 1. The argument specification and the code to handle it are written in the
-#    same place.
-# 2. It can output an option summary; you don't need to maintain this string
-#    separately.
-# 3. Optional and mandatory arguments are specified very gracefully.
-# 4. Arguments can be automatically converted to a specified class.
-# 5. Arguments can be restricted to a certain set.
-#
-# All of these features are demonstrated in the examples below.  See
-# #make_switch for full documentation.
-#
-# === Minimal example
-#
-#   require 'optparse'
-#
-#   options = {}
-#   OptionParser.new do |opts|
-#     opts.banner = "Usage: example.rb [options]"
-#
-#     opts.on("-v", "--[no-]verbose", "Run verbosely") do |v|
-#       options[:verbose] = v
-#     end
-#   end.parse!
-#
-#   p options
-#   p ARGV
-#
-# === Complete example
-#
-# The following example is a complete Ruby program.  You can run it and see the
-# effect of specifying various options.  This is probably the best way to learn
-# the features of +optparse+.
-#
-#   require 'optparse'
-#   require 'optparse/time'
-#   require 'ostruct'
-#   require 'pp'
-#
-#   class OptparseExample
-#
-#     CODES = %w[iso-2022-jp shift_jis euc-jp utf8 binary]
-#     CODE_ALIASES = { "jis" => "iso-2022-jp", "sjis" => "shift_jis" }
-#
-#     #
-#     # Return a structure describing the options.
-#     #
-#     def self.parse(args)
-#       # The options specified on the command line will be collected in *options*.
-#       # We set default values here.
-#       options = OpenStruct.new
-#       options.library = []
-#       options.inplace = false
-#       options.encoding = "utf8"
-#       options.transfer_type = :auto
-#       options.verbose = false
-#
-#       opts = OptionParser.new do |opts|
-#         opts.banner = "Usage: example.rb [options]"
-#
-#         opts.separator ""
-#         opts.separator "Specific options:"
-#
-#         # Mandatory argument.
-#         opts.on("-r", "--require LIBRARY",
-#                 "Require the LIBRARY before executing your script") do |lib|
-#           options.library << lib
-#         end
-#
-#         # Optional argument; multi-line description.
-#         opts.on("-i", "--inplace [EXTENSION]",
-#                 "Edit ARGV files in place",
-#                 "  (make backup if EXTENSION supplied)") do |ext|
-#           options.inplace = true
-#           options.extension = ext || ''
-#           options.extension.sub!(/\A\.?(?=.)/, ".")  # Ensure extension begins with dot.
-#         end
-#
-#         # Cast 'delay' argument to a Float.
-#         opts.on("--delay N", Float, "Delay N seconds before executing") do |n|
-#           options.delay = n
-#         end
-#
-#         # Cast 'time' argument to a Time object.
-#         opts.on("-t", "--time [TIME]", Time, "Begin execution at given time") do |time|
-#           options.time = time
-#         end
-#
-#         # Cast to octal integer.
-#         opts.on("-F", "--irs [OCTAL]", OptionParser::OctalInteger,
-#                 "Specify record separator (default \\0)") do |rs|
-#           options.record_separator = rs
-#         end
-#
-#         # List of arguments.
-#         opts.on("--list x,y,z", Array, "Example 'list' of arguments") do |list|
-#           options.list = list
-#         end
-#
-#         # Keyword completion.  We are specifying a specific set of arguments (CODES
-#         # and CODE_ALIASES - notice the latter is a Hash), and the user may provide
-#         # the shortest unambiguous text.
-#         code_list = (CODE_ALIASES.keys + CODES).join(',')
-#         opts.on("--code CODE", CODES, CODE_ALIASES, "Select encoding",
-#                 "  (#{code_list})") do |encoding|
-#           options.encoding = encoding
-#         end
-#
-#         # Optional argument with keyword completion.
-#         opts.on("--type [TYPE]", [:text, :binary, :auto],
-#                 "Select transfer type (text, binary, auto)") do |t|
-#           options.transfer_type = t
-#         end
-#
-#         # Boolean switch.
-#         opts.on("-v", "--[no-]verbose", "Run verbosely") do |v|
-#           options.verbose = v
-#         end
-#
-#         opts.separator ""
-#         opts.separator "Common options:"
-#
-#         # No argument, shows at tail.  This will print an options summary.
-#         # Try it and see!
-#         opts.on_tail("-h", "--help", "Show this message") do
-#           puts opts
-#           exit
-#         end
-#
-#         # Another typical switch to print the version.
-#         opts.on_tail("--version", "Show version") do
-#           puts OptionParser::Version.join('.')
-#           exit
-#         end
-#       end
-#
-#       opts.parse!(args)
-#       options
-#     end  # parse()
-#
-#   end  # class OptparseExample
-#
-#   options = OptparseExample.parse(ARGV)
-#   pp options
-#
-# === Shell Completion
-#
-# For modern shells (e.g. bash, zsh, etc.), you can use shell
-# completion for command line options.
-#

-#
-# The above examples should be enough to learn how to use this class.  If you

-  # [Argument style:]
-  #   One of the following:

-  # [Argument pattern:]
-  #   Acceptable option argument format, must be pre-defined with
-  #   OptionParser.accept or OptionParser#accept, or Regexp. This can appear
-  #   once or assigned as String if not present, otherwise causes an
-  #   ArgumentError. Examples:
-  #     Float, Time, Array
-  #
-  # [Possible argument values:]
-  #   Hash or Array.
-  #     [:text, :binary, :auto]
-  #     %w[iso-2022-jp shift_jis euc-jp utf8 binary]
-  #     { "jis" => "iso-2022-jp", "sjis" => "shift_jis" }
-  #
-  # [Long style switch:]
-  #   Specifies a long style switch which takes a mandatory, optional or no
-  #   argument. It's a string of the following form:
-  #     "--switch=MANDATORY" or "--switch MANDATORY"
-  #     "--switch[=OPTIONAL]"
-  #     "--switch"
-  #
-  # [Short style switch:]
-  #   Specifies short style switch which takes a mandatory, optional or no
-  #   argument. It's a string of the following form:
-  #     "-xMANDATORY"
-  #     "-x[OPTIONAL]"
-  #     "-x"
-  #   There is also a special form which matches character range (not full
-  #   set of regular expression):
-  #     "-[a-z]MANDATORY"
-  #     "-[a-z][OPTIONAL]"
-  #     "-[a-z]"

-  # [Argument style and description:]
-  #   Instead of specifying mandatory or optional arguments directly in the
-  #   switch parameter, this separate parameter can be used.
-  #     "=MANDATORY"
-  #     "=[OPTIONAL]"
-  #
-  # [Description:]
-  #   Description string for the option.
-  #     "Run verbosely"
-  #
-  # [Handler:]
-  #   Handler for the parsed argument value. Either give a block or pass a
-  #   Proc or Method as an argument.

-# = ostruct.rb: OpenStruct implementation
-#
-# Author:: Yukihiro Matsumoto
-# Documentation:: Gavin Sinclair
-#
-# OpenStruct allows the creation of data objects with arbitrary attributes.
-# See OpenStruct for an example.
-#
-
-#
-# An OpenStruct is a data structure, similar to a Hash, that allows the
-# definition of arbitrary attributes with their accompanying values. This is
-# accomplished by using Ruby's metaprogramming to define methods on the class
-# itself.
-#
-# == Examples:
-#
-#   require 'ostruct'
-#
-#   person = OpenStruct.new
-#   person.name    = "John Smith"
-#   person.age     = 70
-#   person.pension = 300
-#
-#   puts person.name     # -> "John Smith"
-#   puts person.age      # -> 70
-#   puts person.address  # -> nil
-#
-# An OpenStruct employs a Hash internally to store the methods and values and
-# can even be initialized with one:
-#
-#   australia = OpenStruct.new(:country => "Australia", :population => 20_000_000)
-#   p australia   # -> <OpenStruct country="Australia" population=20000000>
-#
-# Hash keys with spaces or characters that would normally not be able to use for
-# method calls (e.g. ()[]*) will not be immediately available on the
-# OpenStruct object as a method for retrieval or assignment, but can be still be
-# reached through the Object#send method.
-#
-#   measurements = OpenStruct.new("length (in inches)" => 24)
-#   measurements.send("length (in inches)")  # -> 24
-#
-#   data_point = OpenStruct.new(:queued? => true)
-#   data_point.queued?                       # -> true
-#   data_point.send("queued?=",false)
-#   data_point.queued?                       # -> false
-#
-# Removing the presence of a method requires the execution the delete_field
-# method as setting the property value to +nil+ will not remove the method.
-#
-#   first_pet = OpenStruct.new(:name => 'Rowdy', :owner => 'John Smith')
-#   first_pet.owner = nil
-#   second_pet = OpenStruct.new(:name => 'Rowdy')
-#
-#   first_pet == second_pet   # -> false
-#
-#   first_pet.delete_field(:owner)
-#   first_pet == second_pet   # -> true
-#
-#
-# == Implementation:
-#
-# An OpenStruct utilizes Ruby's method lookup structure to and find and define
-# the necessary methods for properties. This is accomplished through the method
-# method_missing and define_method.
-#
-# This should be a consideration if there is a concern about the performance of
-# the objects that are created, as there is much more overhead in the setting
-# of these properties compared to using a Hash or a Struct.
-#
-class OpenStruct
-  #
-  # Creates a new OpenStruct object.  By default, the resulting OpenStruct
-  # object will have no attributes.
-  #
-  # The optional +hash+, if given, will generate attributes and values.
-  # For example:
-  #
-  #   require 'ostruct'
-  #   hash = { "country" => "Australia", :population => 20_000_000 }
-  #   data = OpenStruct.new(hash)
-  #
-  #   p data        # -> <OpenStruct country="Australia" population=20000000>
-  #
-  def initialize(hash=nil)
-    @table = {}
-    if hash
-      for k,v in hash
-        @table[k.to_sym] = v
-        new_ostruct_member(k)
-      end
-    end

-# = Output Customization
-# To define your customized pretty printing function for your classes,
-# redefine a method #pretty_print(+pp+) in the class.
-# It takes an argument +pp+ which is an instance of the class PP.
-# The method should use PP#text, PP#breakable, PP#nest, PP#group and
-# PP#pp to print the object.

-# This class implements a pretty printing algorithm. It finds line breaks and
-# nice indentations for grouped structure.
-#
-# By default, the class assumes that primitive elements are strings and each
-# byte in the strings have single column in width. But it can be used for
-# other situations by giving suitable arguments for some methods:
-# * newline object and space generation block for PrettyPrint.new
-# * optional width argument for PrettyPrint#text
-# * PrettyPrint#breakable
-#
-# There are several candidate uses:
-# * text formatting using proportional fonts
-# * multibyte characters which has columns different to number of bytes
-# * non-string formatting
-#
-# == Bugs
-# * Box based formatting?
-# * Other (better) model/algorithm?

-#
-# == Retrieving the instance
-#
-# +Prime+.new is obsolete. Now +Prime+ has the default instance and you can
-# access it as +Prime+.instance.
-#
-# For convenience, each instance method of +Prime+.instance can be accessed
-# as a class method of +Prime+.

-#
-# == Generators
-#
-# A "generator" provides an implementation of enumerating pseudo-prime
-# numbers and it remembers the position of enumeration and upper bound.
-# Futhermore, it is a external iterator of prime enumeration which is
-# compatible to an Enumerator.
-#
-# +Prime+::+PseudoPrimeGenerator+ is the base class for generators.
-# There are few implementations of generator.
-#
-# [+Prime+::+EratosthenesGenerator+]
-#   Uses eratosthenes's sieve.
-# [+Prime+::+TrialDivisionGenerator+]
-#   Uses the trial division method.
-# [+Prime+::+Generator23+]
-#   Generates all positive integers which is not divided by 2 nor 3.
-#   This sequence is very bad as a pseudo-prime sequence. But this
-#   is faster and uses much less memory than other generators. So,
-#   it is suitable for factorizing an integer which is not large but
-#   has many prime factors. e.g. for Prime#prime? .

-  #
-  # == Description
-  #

-  #
-  # == Example

-# = PStore -- Transactional File Storage for Ruby Objects
-#
-# pstore.rb -
-#   originally by matz
-#   documentation by Kev Jackson and James Edward Gray II
-#   improved by Hongli Lai
-#
-# See PStore for documentation.
-
-
-require "fileutils"
-require "digest/md5"
-require "thread"
-
-#
-# PStore implements a file based persistence mechanism based on a Hash.  User
-# code can store hierarchies of Ruby objects (values) into the data store file
-# by name (keys).  An object hierarchy may be just a single object.  User code
-# may later read values back from the data store or even update data, as needed.
-#
-# The transactional behavior ensures that any changes succeed or fail together.
-# This can be used to ensure that the data store is not left in a transitory
-# state, where some values were updated but others were not.
-#
-# Behind the scenes, Ruby objects are stored to the data store file with
-# Marshal.  That carries the usual limitations.  Proc objects cannot be
-# marshalled, for example.
-#
-# == Usage example:
-#
-#  require "pstore"
-#
-#  # a mock wiki object...
-#  class WikiPage
-#    def initialize( page_name, author, contents )
-#      @page_name = page_name
-#      @revisions = Array.new
-#
-#      add_revision(author, contents)
-#    end
-#
-#    attr_reader :page_name
-#
-#    def add_revision( author, contents )
-#      @revisions << { :created  => Time.now,
-#                      :author   => author,
-#                      :contents => contents }
-#    end
-#
-#    def wiki_page_references
-#      [@page_name] + @revisions.last[:contents].scan(/\b(?:[A-Z]+[a-z]+){2,}/)
-#    end
-#
-#    # ...
-#  end
-#
-#  # create a new page...
-#  home_page = WikiPage.new( "HomePage", "James Edward Gray II",
-#                            "A page about the JoysOfDocumentation..." )
-#
-#  # then we want to update page data and the index together, or not at all...
-#  wiki = PStore.new("wiki_pages.pstore")
-#  wiki.transaction do  # begin transaction; do all of this or none of it
-#    # store page...
-#    wiki[home_page.page_name] = home_page
-#    # ensure that an index has been created...
-#    wiki[:wiki_index] ||= Array.new
-#    # update wiki index...
-#    wiki[:wiki_index].push(*home_page.wiki_page_references)
-#  end                   # commit changes to wiki data store file
-#
-#  ### Some time later... ###
-#
-#  # read wiki data...
-#  wiki.transaction(true) do  # begin read-only transaction, no changes allowed
-#    wiki.roots.each do |data_root_name|
-#      p data_root_name
-#      p wiki[data_root_name]
-#    end
-#  end
-#
-# == Transaction modes
-#
-# By default, file integrity is only ensured as long as the operating system
-# (and the underlying hardware) doesn't raise any unexpected I/O errors. If an
-# I/O error occurs while PStore is writing to its file, then the file will
-# become corrupted.
-#
-# You can prevent this by setting <em>pstore.ultra_safe = true</em>.
-# However, this results in a minor performance loss, and only works on platforms
-# that support atomic file renames. Please consult the documentation for
-# +ultra_safe+ for details.
-#
-# Needless to say, if you're storing valuable data with PStore, then you should
-# backup the PStore files from time to time.

-    # * <b>%p</b> -- The complete path.
-    # * <b>%f</b> -- The base file name of the path, with its file extension,
-    #   but without any directories.
-    # * <b>%n</b> -- The file name of the path without its file extension.
-    # * <b>%d</b> -- The directory list of the path.
-    # * <b>%x</b> -- The file extension of the path.  An empty string if there
-    #   is no extension.
-    # * <b>%X</b> -- Everything *but* the file extension.
-    # * <b>%s</b> -- The alternate file separator if defined, otherwise use
-    #   the standard file separator.
-    # * <b>%%</b> -- A percent sign.
-    #
-    # The %d specifier can also have a numeric prefix (e.g. '%2d'). If the
-    # number is positive, only return (up to) +n+ directories in the path,
-    # starting from the left hand side.  If +n+ is negative, return (up to)
-    # |+n+| directories from the right hand side of the path.
-    #
-    # Examples:
-    #
-    #   'a/b/c/d/file.txt'.pathmap("%2d")   => 'a/b'
-    #   'a/b/c/d/file.txt'.pathmap("%-2d")  => 'c/d'
-    #
-    # Also the %d, %p, %f, %n, %x, and %X operators can take a
-    # pattern/replacement argument to perform simple string substitutions on a
-    # particular part of the path.  The pattern and replacement are separated
-    # by a comma and are enclosed by curly braces.  The replacement spec comes
-    # after the % character but before the operator letter.  (e.g.
-    # "%{old,new}d").  Multiple replacement specs should be separated by
-    # semi-colons (e.g. "%{old,new;src,bin}d").
-    #
-    # Regular expressions may be used for the pattern, and back refs may be
-    # used in the replacement text.  Curly braces, commas and semi-colons are
-    # excluded from both the pattern and replacement text (let's keep parsing
-    # reasonable).
-    #
-    # For example:
-    #
-    #    "src/org/onestepback/proj/A.java".pathmap("%{^src,bin}X.class")
-    #
-    # returns:
-    #
-    #    "bin/org/onestepback/proj/A.class"
-    #
-    # If the replacement text is '*', then a block may be provided to perform
-    # some arbitrary calculation for the replacement.
-    #
-    # For example:
-    #
-    #   "/path/to/file.TXT".pathmap("%X%{.*,*}x") { |ext|
-    #      ext.downcase

-  # A FileList is essentially an array with a few helper methods defined to
-  # make file manipulation a bit easier.
-  #
-  # FileLists are lazy.  When given a list of glob patterns for possible files
-  # to be included in the file list, instead of searching the file structures
-  # to find the files, a FileList holds the pattern for latter use.
-  #
-  # This allows us to define a number of FileList to match any number of
-  # files, but only search out the actual files when then FileList itself is
-  # actually used.  The key is that the first time an element of the
-  # FileList/Array is requested, the pending patterns are resolved into a real
-  # list of file names.
-  #
-  class FileList
-
-    include Cloneable
-
-    # == Method Delegation
-    #
-    # The lazy evaluation magic of FileLists happens by implementing all the
-    # array specific methods to call +resolve+ before delegating the heavy
-    # lifting to an embedded array object (@items).
-    #
-    # In addition, there are two kinds of delegation calls.  The regular kind
-    # delegates to the @items array and returns the result directly.  Well,
-    # almost directly.  It checks if the returned value is the @items object
-    # itself, and if so will return the FileList object instead.
-    #
-    # The second kind of delegation call is used in methods that normally
-    # return a new Array object.  We want to capture the return value of these
-    # methods and wrap them in a new FileList object.  We enumerate these
-    # methods in the +SPECIAL_RETURN+ list below.
-
-    # List of array methods (that are not in +Object+) that need to be
-    # delegated.

-    #
-    # Create a documentation task that will generate the RDoc files for
-    # a project.
-    #
-    # The RDocTask will create the following targets:
-    #
-    # [<b><em>rdoc</em></b>]
-    #   Main task for this RDOC task.
-    #
-    # [<b>:clobber_<em>rdoc</em></b>]

-    #
-    # [<b>:re<em>rdoc</em></b>]
-    #   Rebuild the rdoc files from scratch, even if they are not out
-    #   of date.
-    #
-    # Simple Example:
-    #
-    #   Rake::RDocTask.new do |rd|
-    #     rd.main = "README.rdoc"
-    #     rd.rdoc_files.include("README.rdoc", "lib/**/*.rb")
-    #   end
-    #
-    # The +rd+ object passed to the block is an RDocTask object. See the
-    # attributes list for the RDocTask class for available customization options.
-    #
-    # == Specifying different task names
-    #
-    # You may wish to give the task a different name, such as if you are
-    # generating two sets of documentation.  For instance, if you want to have a
-    # development set of documentation including private methods:
-    #
-    #   Rake::RDocTask.new(:rdoc_dev) do |rd|
-    #     rd.main = "README.doc"

-    #     rd.options << "--all"

-    # The tasks would then be named :<em>rdoc_dev</em>, :clobber_<em>rdoc_dev</em>, and
-    # :re<em>rdoc_dev</em>.

-    # first argument. With the <tt>:rdoc</tt>, <tt>:clobber_rdoc</tt> and
-    # <tt>:rerdoc</tt> options, you can customize the task names to your liking.
-    # For example:
-    #
-    #   Rake::RDocTask.new(:rdoc => "rdoc", :clobber_rdoc => "rdoc:clean", :rerdoc => "rdoc:force")

-# to JavaDoc, parsing the source and extracting the definition for classes,
-# modules, methods, includes and requires.  It associates these with optional
-# documentation contained in an immediately preceding comment block then
-# renders the result using an output formatter.
-#
-# RDoc::Markup that converts plain text into various output formats.  The
-# markup library is used to interpret the comment blocks that RDoc uses to
-# document methods, classes, and so on.
-#
-# RDoc::RI implements the +ri+ command-line tool which displays on-line
-# documentation for ruby classes, methods, etc.  +ri+ features several output
-# formats and an interactive mode (<tt>ri -i</tt>).  See <tt>ri --help</tt>
-# for further details.
-#
-# == Roadmap
-#
-# * If you want to use RDoc to create documentation for your Ruby source files,
-#   see RDoc::Markup and refer to <tt>rdoc --help</tt> for command line
-#   usage.
-# * If you want to write documentation for Ruby files see RDoc::Parser::Ruby
-# * If you want to write documentation for extensions written in C see
-#   RDoc::Parser::C
-# * If you want to generate documentation using <tt>rake</tt> see RDoc::Task.
-# * If you want to drive RDoc programmatically, see RDoc::RDoc.
-# * If you want to use the library to format text blocks into HTML, look at
-#   RDoc::Markup.
-# * If you want to make an RDoc plugin such as a generator or directive
-#   handler see RDoc::RDoc.
-# * If you want to write your own output generator see RDoc::Generator.
-#
-# == Summary
-#
-# Once installed, you can create documentation using the +rdoc+ command
-#
-#   % rdoc [options] [names...]
-#
-# For an up-to-date option summary, type
-#
-#   % rdoc --help
-#
-# A typical use might be to generate documentation for a package of Ruby
-# source (such as RDoc itself).
-#
-#   % rdoc
-#
-# This command generates documentation for all the Ruby and C source
-# files in and below the current directory.  These will be stored in a
-# documentation tree starting in the subdirectory +doc+.
-#
-# You can make this slightly more useful for your readers by having the
-# index page contain the documentation for the primary file.  In our
-# case, we could type
-#
-#   % rdoc --main README.txt
-#
-# You'll find information on the various formatting tricks you can use
-# in comment blocks in the documentation this generates.
-#
-# RDoc uses file extensions to determine how to process each file.  File names
-# ending +.rb+ and +.rbw+ are assumed to be Ruby source.  Files
-# ending +.c+ are parsed as C files.  All other files are assumed to
-# contain just Markup-style markup (with or without leading '#' comment
-# markers).  If directory names are passed to RDoc, they are scanned
-# recursively for C and Ruby source files only.
-#
-# == Other stuff
-#
-# RDoc is currently being maintained by Eric Hodel <drbrain@segment7.net>.
-#
-# Dave Thomas <dave@pragmaticprogrammer.com> is the original author of RDoc.
-#
-# == Credits
-#
-# * The Ruby parser in rdoc/parse.rb is based heavily on the outstanding
-#   work of Keiju ISHITSUKA of Nippon Rational Inc, who produced the Ruby
-#   parser for irb and the rtags package.

-##
-# RDoc::Markup parses plain text documents and attempts to decompose them into
-# their constituent parts.  Some of these parts are high-level: paragraphs,
-# chunks of verbatim text, list entries and the like.  Other parts happen at
-# the character level: a piece of bold text, a word in code font.  This markup
-# is similar in spirit to that used on WikiWiki webs, where folks create web
-# pages using a simple set of formatting rules.
-#
-# RDoc::Markup itself does no output formatting: this is left to a different
-# set of classes.
-#
-# RDoc::Markup is extendable at runtime: you can add \new markup elements to
-# be recognised in the documents that RDoc::Markup parses.
-#
-# RDoc::Markup is intended to be the basis for a family of tools which share
-# the common requirement that simple, plain-text should be rendered in a
-# variety of different output formats and media.  It is envisaged that
-# RDoc::Markup could be the basis for formatting RDoc style comment blocks,
-# Wiki entries, and online FAQs.
-#
-# == Synopsis
-#
-# This code converts +input_string+ to HTML.  The conversion takes place in
-# the +convert+ method, so you can use the same RDoc::Markup converter to
-# convert multiple input strings.
-#
-#   require 'rdoc/markup/to_html'
-#
-#   h = RDoc::Markup::ToHtml.new
-#
-#   puts h.convert(input_string)
-#
-# You can extend the RDoc::Markup parser to recognise new markup
-# sequences, and to add special processing for text that matches a
-# regular expression.  Here we make WikiWords significant to the parser,
-# and also make the sequences {word} and \<no>text...</no> signify
-# strike-through text.  We then subclass the HTML output class to deal
-# with these:
-#
-#   require 'rdoc/markup'
-#   require 'rdoc/markup/to_html'
-#
-#   class WikiHtml < RDoc::Markup::ToHtml
-#     def handle_special_WIKIWORD(special)
-#       "<font color=red>" + special.text + "</font>"
-#     end
-#   end
-#
-#   markup = RDoc::Markup.new
-#   markup.add_word_pair("{", "}", :STRIKE)
-#   markup.add_html("no", :STRIKE)
-#
-#   markup.add_special(/\b([A-Z][a-z]+[A-Z]\w+)/, :WIKIWORD)
-#
-#   wh = WikiHtml.new markup
-#   wh.add_tag(:STRIKE, "<strike>", "</strike>")
-#
-#   puts "<body>#{wh.convert ARGF.read}</body>"
-#
-# == Encoding
-#
-# Where Encoding support is available, RDoc will automatically convert all
-# documents to the same output encoding.  The output encoding can be set via
-# RDoc::Options#encoding and defaults to Encoding.default_external.
-#
-# = \RDoc Markup Reference
-#
-# == Block Markup
-#
-# === Paragraphs and Verbatim
-#
-# The markup engine looks for a document's natural left margin.  This is
-# used as the initial margin for the document.
-#
-# Consecutive lines starting at this margin are considered to be a
-# paragraph. Empty lines separate paragraphs.
-#
-# Any line that starts to the right of the current margin is treated
-# as verbatim text.  This is useful for code listings:
-#
-#   3.times { puts "Ruby" }
-#
-# In verbatim text, two or more blank lines are collapsed into one,
-# and trailing blank lines are removed:
-#
-#   This is the first line
-#
-#
-#   This is the second non-blank line,
-#   after 2 blank lines in the source markup.
-#
-#
-# There were two trailing blank lines right above this paragraph, that
-# have been removed. In addition, the verbatim text has been shifted
-# left, so the amount of indentation of verbatim text is unimportant.
-#
-# === Headers and Rules
-#
-# A line starting with an equal sign (=) is treated as a
-# heading.  Level one headings have one equals sign, level two headings
-# have two, and so on until level six, which is the maximum
-# (seven hyphens or more result in a level six heading).
-#
-# For example, the above header was obtained with:
-#   == Headers and Rules
-#
-# A line starting with three or more hyphens (at the current indent)
-# generates a horizontal rule.  The more hyphens, the thicker the rule
-# (within reason, and if supported by the output device).
-#
-# In the case of HTML output, three dashes generate a 1-pixel high rule,
-# four dashes result in 2 pixels, and so on. The actual height is limited
-# to 10 pixels:
-#
-#   ---
-#   -----
-#   -----------------------------------------------------
-#
-# produces:
-#
-# ---
-# -----
-# -----------------------------------------------------
-#
-# === Simple Lists
-#
-# If a paragraph starts with a "*", "-", "<digit>." or "<letter>.",
-# then it is taken to be the start of a list.  The margin is increased to be
-# the first non-space following the list start flag.  Subsequent lines
-# should be indented to this new margin until the list ends.  For example:
-#
-#   * this is a list with three paragraphs in
-#     the first item.  This is the first paragraph.
-#
-#     And this is the second paragraph.
-#
-#     1. This is an indented, numbered list.
-#     2. This is the second item in that list
-#
-#     This is the third conventional paragraph in the
-#     first list item.
-#
-#   * This is the second item in the original list
-#
-# produces:
-#
-# * this is a list with three paragraphs in
-#   the first item.  This is the first paragraph.
-#
-#   And this is the second paragraph.
-#
-#   1. This is an indented, numbered list.
-#   2. This is the second item in that list
-#
-#   This is the third conventional paragraph in the
-#   first list item.
-#
-# * This is the second item in the original list
-#
-# === Labeled Lists
-#
-# You can also construct labeled lists, sometimes called description
-# or definition lists.  Do this by putting the label in square brackets
-# and indenting the list body:
-#
-#   [cat]  a small furry mammal
-#          that seems to sleep a lot
-#
-#   [ant]  a little insect that is known
-#          to enjoy picnics
-#
-# produces:
-#
-# [cat]  a small furry mammal
-#        that seems to sleep a lot
-#
-# [ant]  a little insect that is known
-#        to enjoy picnics
-#
-# If you want the list bodies to line up to the left of the labels,
-# use two colons:
-#
-#   cat::  a small furry mammal
-#          that seems to sleep a lot
-#
-#   ant::  a little insect that is known
-#          to enjoy picnics
-#
-# produces:
-#
-# cat::  a small furry mammal
-#        that seems to sleep a lot
-#
-# ant::  a little insect that is known
-#        to enjoy picnics
-#
-# Notice that blank lines right after the label are ignored in labeled lists:
-#
-#   [one]
-#
-#       definition 1
-#
-#   [two]
-#
-#       definition 2
-#
-# produces the same output as
-#
-#   [one]  definition 1
-#   [two]  definition 2
-#
-#
-# === Lists and Verbatim
-#
-# If you want to introduce a verbatim section right after a list, it has to be
-# less indented than the list item bodies, but more indented than the list
-# label, letter, digit or bullet. For instance:
-#
-#   *   point 1
-#
-#   *   point 2, first paragraph
-#
-#       point 2, second paragraph
-#         verbatim text inside point 2
-#       point 2, third paragraph
-#     verbatim text outside of the list (the list is therefore closed)
-#   regular paragraph after the list
-#
-# produces:
-#
-# *   point 1
-#
-# *   point 2, first paragraph
-#
-#     point 2, second paragraph
-#       verbatim text inside point 2
-#     point 2, third paragraph
-#   verbatim text outside of the list (the list is therefore closed)
-# regular paragraph after the list
-#
-#
-# == Text Markup
-#
-# === Bold, Italic, Typewriter Text
-#
-# You can use markup within text (except verbatim) to change the
-# appearance of parts of that text.  Out of the box, RDoc::Markup
-# supports word-based and general markup.
-#
-# Word-based markup uses flag characters around individual words:
-#
-# <tt>\*_word_\*</tt>::  displays _word_ in a *bold* font
-# <tt>\__word_\_</tt>::  displays _word_ in an _emphasized_ font
-# <tt>\+_word_\+</tt>::  displays _word_ in a +code+ font
-#
-# General markup affects text between a start delimiter and an end
-# delimiter.  Not surprisingly, these delimiters look like HTML markup.
-#
-# <tt>\<b>_text_</b></tt>::    displays _text_ in a *bold* font
-# <tt>\<em>_text_</em></tt>::  displays _text_ in an _emphasized_ font
-#                              (alternate tag: <tt>\<i></tt>)
-# <tt>\<tt>_text_\</tt></tt>:: displays _text_ in a +code+ font
-#                              (alternate tag: <tt>\<code></tt>)
-#
-# Unlike conventional Wiki markup, general markup can cross line
-# boundaries.  You can turn off the interpretation of markup by
-# preceding the first character with a backslash (see <i>Escaping
-# Text Markup</i>, below).
-#
-# === Links
-#
-# Links to starting with +http:+, +https:+, +mailto:+, +ftp:+ or +www.+
-# are recognized.  An HTTP url that references an external image file is
-# converted into an inline image element.
-#
-# Links starting with <tt>rdoc-ref:</tt> will link to the referenced class,
-# module, method, file, etc.  If the referenced item is not documented the
-# text will be and no link will be generated.
-#
-# Links starting with +link:+ refer to local files whose path is relative to
-# the <tt>--op</tt> directory.
-#
-# Links can also be of the form <tt>label[url]</tt>, in which case +label+ is
-# used in the displayed text, and +url+ is used as the target.  If +label+
-# contains multiple words, put it in braces: <tt>{multi word label}[url]</tt>.
-# The +url+ may be an +http:+-type link or a cross-reference to a class,
-# module or method with a label.
-#
-# Links with the <tt>rdoc-ref:</tt> scheme will link to the referenced class,
-# module, method, file, etc.  If the referenced item is does not exist
-# no link will be generated and <tt>rdoc-ref:</tt> will be removed from the
-# resulting text.
-#
-# Links starting with +link:+ refer to local files whose path is relative to
-# the <tt>--op</tt> directory.  Use <tt>rdoc-ref:</tt> instead of
-# <tt>link:</tt> to link to files generated by RDoc as the link target may
-# be different across RDoc generators.
-#
-# Example links:
-#
-#   https://github.com/rdoc/rdoc
-#   mailto:user@example.com
-#   {RDoc Documentation}[http://rdoc.rubyforge.org]
-#   {RDoc Markup}[rdoc-ref:RDoc::Markup]
-#
-# === Escaping Text Markup
-#
-# Text markup can be escaped with a backslash, as in \<tt>, which was obtained
-# with <tt>\\<tt></tt>.  Except in verbatim sections and between \<tt> tags,
-# to produce a backslash you have to double it unless it is followed by a
-# space, tab or newline. Otherwise, the HTML formatter will discard it, as it
-# is used to escape potential links:
-#
-#   * The \ must be doubled if not followed by white space: \\.
-#   * But not in \<tt> tags: in a Regexp, <tt>\S</tt> matches non-space.
-#   * This is a link to {ruby-lang}[www.ruby-lang.org].
-#   * This is not a link, however: \{ruby-lang.org}[www.ruby-lang.org].
-#   * This will not be linked to \RDoc::RDoc#document
-#
-# generates:
-#
-# * The \ must be doubled if not followed by white space: \\.
-# * But not in \<tt> tags: in a Regexp, <tt>\S</tt> matches non-space.
-# * This is a link to {ruby-lang}[www.ruby-lang.org]
-# * This is not a link, however: \{ruby-lang.org}[www.ruby-lang.org]
-# * This will not be linked to \RDoc::RDoc#document
-#
-# Inside \<tt> tags, more precisely, leading backslashes are removed only if
-# followed by a markup character (<tt><*_+</tt>), a backslash, or a known link
-# reference (a known class or method). So in the example above, the backslash
-# of <tt>\S</tt> would be removed if there was a class or module named +S+ in
-# the current context.
-#
-# This behavior is inherited from RDoc version 1, and has been kept for
-# compatibility with existing RDoc documentation.
-#
-# === Conversion of characters
-#
-# HTML will convert two/three dashes to an em-dash. Other common characters are
-# converted as well:
-#
-#   em-dash::  -- or ---
-#   ellipsis:: ...
-#
-#   single quotes:: 'text' or `text'
-#   double quotes:: "text" or ``text''
-#
-#   copyright:: (c)
-#   registered trademark:: (r)
-#
-# produces:
-#
-# em-dash::  -- or ---
-# ellipsis:: ...
-#
-# single quotes:: 'text' or `text'
-# double quotes:: "text" or ``text''
-#
-# copyright:: (c)
-# registered trademark:: (r)
-#
-#
-# == Documenting Source Code
-#
-# Comment blocks can be written fairly naturally, either using <tt>#</tt> on
-# successive lines of the comment, or by including the comment in
-# a <tt>=begin</tt>/<tt>=end</tt> block.  If you use the latter form,
-# the <tt>=begin</tt> line _must_ be flagged with an +rdoc+ tag:
-#
-#   =begin rdoc
-#   Documentation to be processed by RDoc.
-#
-#   ...
-#   =end
-#
-# RDoc stops processing comments if it finds a comment line starting
-# with <tt>--</tt> right after the <tt>#</tt> character (otherwise,
-# it will be treated as a rule if it has three dashes or more).
-# This can be used to separate external from internal comments,
-# or to stop a comment being associated with a method, class, or module.
-# Commenting can be turned back on with a line that starts with <tt>++</tt>.
-#
-#   ##
-#   # Extract the age and calculate the date-of-birth.
-#   #--
-#   # FIXME: fails if the birthday falls on February 29th
-#   #++
-#   # The DOB is returned as a Time object.
-#
-#   def get_dob(person)
-#     # ...
-#   end
-#
-# Names of classes, files, and any method names containing an underscore or
-# preceded by a hash character are automatically linked from comment text to
-# their description. This linking works inside the current class or module,
-# and with ancestor methods (in included modules or in the superclass).
-#
-# Method parameter lists are extracted and displayed with the method
-# description.  If a method calls +yield+, then the parameters passed to yield
-# will also be displayed:
-#
-#   def fred
-#     ...
-#     yield line, address
-#
-# This will get documented as:
-#
-#   fred() { |line, address| ... }
-#
-# You can override this using a comment containing ':yields: ...' immediately
-# after the method definition
-#
-#   def fred # :yields: index, position
-#     # ...
-#
-#     yield line, address
-#
-# which will get documented as
-#
-#    fred() { |index, position| ... }
-#
-# +:yields:+ is an example of a documentation directive.  These appear
-# immediately after the start of the document element they are modifying.
-#
-# RDoc automatically cross-references words with underscores or camel-case.
-# To suppress cross-references, prefix the word with a \ character.  To
-# include special characters like "<tt>\n</tt>", you'll need to use
-# two \ characters in normal text, but only one in \<tt> text:
-#
-#   "\\n" or "<tt>\n</tt>"
-#
-# produces:
-#
-# "\\n" or "<tt>\n</tt>"
-#
-# == Directives
-#
-# Directives are keywords surrounded by ":" characters.
-#
-# === Controlling what is documented
-#
-# [+:nodoc:+ / <tt>:nodoc: all</tt>]
-#   This directive prevents documentation for the element from
-#   being generated.  For classes and modules, methods, aliases,
-#   constants, and attributes directly within the affected class or
-#   module also will be omitted.  By default, though, modules and
-#   classes within that class or module _will_ be documented.  This is
-#   turned off by adding the +all+ modifier.
-#
-#     module MyModule # :nodoc:
-#       class Input
-#       end
-#     end
-#
-#     module OtherModule # :nodoc: all
-#       class Output
-#       end
-#     end
-#
-#   In the above code, only class <tt>MyModule::Input</tt> will be documented.
-#
-#   The +:nodoc:+ directive, like +:enddoc:+, +:stopdoc:+ and +:startdoc:+
-#   presented below, is local to the current file: if you do not want to
-#   document a module that appears in several files, specify +:nodoc:+ on each
-#   appearance, at least once per file.
-#
-# [+:stopdoc:+ / +:startdoc:+]
-#   Stop and start adding new documentation elements to the current container.
-#   For example, if a class has a number of constants that you don't want to
-#   document, put a +:stopdoc:+ before the first, and a +:startdoc:+ after the
-#   last.  If you don't specify a +:startdoc:+ by the end of the container,
-#   disables documentation for the rest of the current file.
-#
-# [+:doc:+]
-#   Forces a method or attribute to be documented even if it wouldn't be
-#   otherwise.  Useful if, for example, you want to include documentation of a
-#   particular private method.
-#
-# [+:enddoc:+]
-#   Document nothing further at the current level: directives +:startdoc:+ and
-#   +:doc:+ that appear after this will not be honored for the current container
-#   (file, class or module), in the current file.
-#
-# [+:notnew:+ / +:not_new:+ / +:not-new:+ ]
-#   Only applicable to the +initialize+ instance method.  Normally RDoc
-#   assumes that the documentation and parameters for +initialize+ are
-#   actually for the +new+ method, and so fakes out a +new+ for the class.
-#   The +:notnew:+ directive stops this.  Remember that +initialize+ is private,
-#   so you won't see the documentation unless you use the +-a+ command line
-#   option.
-#
-# === Other directives
-#
-# [+:include:+ _filename_]
-#   Include the contents of the named file at this point. This directive
-#   must appear alone on one line, possibly preceded by spaces. In this
-#   position, it can be escaped with a \ in front of the first colon.
-#
-#   The file will be searched for in the directories listed by the +--include+
-#   option, or in the current directory by default.  The contents of the file
-#   will be shifted to have the same indentation as the ':' at the start of
-#   the +:include:+ directive.
-#
-# [+:title:+ _text_]
-#   Sets the title for the document.  Equivalent to the <tt>--title</tt>
-#   command line parameter.  (The command line parameter overrides any :title:
-#   directive in the source).
-#
-# [+:main:+ _name_]
-#   Equivalent to the <tt>--main</tt> command line parameter.
-#
-# [<tt>:category: section</tt>]
-#   Adds this item to the named +section+ overriding the current section.  Use
-#   this to group methods by section in RDoc output while maintaining a
-#   sensible ordering (like alphabetical).
-#
-#     # :category: Utility Methods
-#     #
-#     # CGI escapes +text+
-#
-#     def convert_string text
-#       CGI.escapeHTML text
-#     end
-#
-#   An empty category will place the item in the default category:
-#
-#     # :category:
-#     #
-#     # This method is in the default category
-#
-#     def some_method
-#       # ...
-#     end
-#
-#   Unlike the :section: directive, :category: is not sticky.  The category
-#   only applies to the item immediately following the comment.
-#
-#   Use the :section: directive to provide introductory text for a section of
-#   documentation.
-#
-# [<tt>:section: title</tt>]
-#   Provides section introductory text in RDoc output.  The title following
-#   +:section:+ is used as the section name and the remainder of the comment
-#   containing the section is used as introductory text.  A section's comment
-#   block must be separated from following comment blocks.  Use an empty title
-#   to switch to the default section.
-#
-#   The :section: directive is sticky, so subsequent methods, aliases,
-#   attributes, and classes will be contained in this section until the
-#   section is changed.  The :category: directive will override the :section:
-#   directive.
-#
-#   A :section: comment block may have one or more lines before the :section:
-#   directive.  These will be removed, and any identical lines at the end of
-#   the block are also removed.  This allows you to add visual cues to the
-#   section.
-#
-#   Example:
-#
-#     # ----------------------------------------
-#     # :section: My Section
-#     # This is the section that I wrote.
-#     # See it glisten in the noon-day sun.
-#     # ----------------------------------------
-#
-#     ##
-#     # Comment for some_method
-#
-#     def some_method
-#       # ...
-#     end
-#
-# [+:call-seq:+]
-#   Lines up to the next blank line in the comment are treated as the method's
-#   calling sequence, overriding the default parsing of method parameters and
-#   yield arguments.
-#
-# Further directives can be found in RDoc::Parser::Ruby and RDoc::Parser::C.

-  Files are parsed, and the information they contain collected, before any
-  output is produced. This allows cross references between all files to be
-  resolved. If a name is a directory, it is traversed. If no names are
-  specified, all Ruby files in the current directory (and subdirectories) are
-  processed.
-
-  How RDoc generates output depends on the output formatter being used, and on
-  the options you give.
-

-  functions similar to the RUBYOPT environment variable for ruby.
-
-    $ export RDOCOPT="--show-hash"

-  always will override those in RDOCOPT.

-#
-# [Document-method: <tt>ClassName#method_name<tt>]

-#
-# [Document-attr: +name+]
-#   Documentation for the named attribute.
-#
-# [call-seq:  <i>text up to an empty line</i>]
-#   Because C source doesn't give descriptive names to Ruby-level parameters,

-#
-# In addition, RDoc assumes by default that the C method implementing a
-# Ruby function is in the same source file as the rb_define_method call.
-# If this isn't the case, add the comment:
-#
-#   rb_define_method(....);  // in filename

-# As an example, we might have an extension that defines multiple classes

-# Extracts code elements from a source file returning a TopLevel object

-#
-# This file is based on rtags
-#
-# RubyParser understands how to document:
-# * classes
-# * modules
-# * methods
-# * constants
-# * aliases
-# * private, public, protected
-# * private_class_function, public_class_function
-# * module_function

-#
-# == Method Arguments
-#
-#--
-# NOTE: I don't think this works, needs tests, remove the paragraph following
-# this block when known to work
-#
-# The parser extracts the arguments from the method definition.  You can
-# override this with a custom argument definition using the :args: directive:
-#
-#   ##
-#   # This method tries over and over until it is tired
-#
-#   def go_go_go(thing_to_try, tries = 10) # :args: thing_to_try
-#     puts thing_to_try
-#     go_go_go thing_to_try, tries - 1
-#   end
-#
-# If you have a more-complex set of overrides you can use the :call-seq:
-# directive:
-#++
-#
-# The parser extracts the arguments from the method definition.  You can
-# override this with a custom argument definition using the :call-seq:
-# directive:
-#
-#   ##
-#   # This method can be called with a range or an offset and length
-#   #
-#   # :call-seq:
-#   #   my_method(Range)
-#   #   my_method(offset, length)
-#
-#   def my_method(*args)
-#   end
-#
-# The parser extracts +yield+ expressions from method bodies to gather the
-# yielded argument names.  If your method manually calls a block instead of
-# yielding or you want to override the discovered argument names use
-# the :yields: directive:
-#
-#   ##
-#   # My method is awesome
-#
-#   def my_method(&block) # :yields: happy, times
-#     block.call 1, 2
-#   end
-#
-# == Metaprogrammed Methods
-#
-# To pick up a metaprogrammed method, the parser looks for a comment starting
-# with '##' before an identifier:
-#
-#   ##
-#   # This is a meta-programmed method!
-#
-#   add_my_method :meta_method, :arg1, :arg2
-#
-# The parser looks at the token after the identifier to determine the name, in
-# this example, :meta_method.  If a name cannot be found, a warning is printed
-# and 'unknown is used.
-#
-# You can force the name of a method using the :method: directive:
-#
-#   ##
-#   # :method: woo_hoo!
-#
-# By default, meta-methods are instance methods.  To indicate that a method is
-# a singleton method instead use the :singleton-method: directive:
-#
-#   ##
-#   # :singleton-method:
-#
-# You can also use the :singleton-method: directive with a name:
-#
-#   ##
-#   # :singleton-method: woo_hoo!
-#
-# Additionally you can mark a method as an attribute by
-# using :attr:, :attr_reader:, :attr_writer: or :attr_accessor:.  Just like
-# for :method:, the name is optional.
-#
-#   ##
-#   # :attr_reader: my_attr_name
-#
-# == Hidden methods and attributes
-#
-# You can provide documentation for methods that don't appear using
-# the :method:, :singleton-method: and :attr: directives:
-#
-#   ##
-#   # :attr_writer: ghost_writer
-#   # There is an attribute here, but you can't see it!
-#
-#   ##
-#   # :method: ghost_method
-#   # There is a method here, but you can't see it!
-#
-#   ##
-#   # this is a comment for a regular method
-#
-#   def regular_method() end
-#
-# Note that by default, the :method: directive will be ignored if there is a
-# standard rdocable item following it.

-  Class | Class::method | Class#method | Class.method | method
-
-All class names may be abbreviated to their minimum unambiguous form. If a name
-is ambiguous, all valid options will be listed.
-
-A '.' matches either class or instance methods, while #method
-matches only instance and ::method matches only class methods.
-
-For example:
-
-    #{opt.program_name} Fil
-    #{opt.program_name} File
-    #{opt.program_name} File.new
-    #{opt.program_name} zip
-
-Note that shell quoting or escaping may be required for method names containing
-punctuation:
-
-    #{opt.program_name} 'Array.[]'
-    #{opt.program_name} compact\\!
-
-To see the default directories ri will search, run:
-
-    #{opt.program_name} --list-doc-dirs
-
-Specifying the --system, --site, --home, --gems or --doc-dir options will
-limit ri to searching only the specified directories.
-
-Options may also be set in the 'RI' environment variable.

-# RDoc::Task creates the following rake tasks to generate and clean up RDoc
-# output:
-#
-# [rdoc]
-#   Main task for this RDoc task.
-#
-# [clobber_rdoc]
-#   Delete all the rdoc files.  This target is automatically added to the main
-#   clobber target.
-#
-# [rerdoc]
-#   Rebuild the rdoc files from scratch, even if they are not out of date.
-#
-# Simple Example:
-#
-#   gem 'rdoc'
-#   require 'rdoc/task'
-#
-#   RDoc::Task.new do |rdoc|
-#     rdoc.main = "README.rdoc"
-#     rdoc.rdoc_files.include("README.rdoc", "lib/**/*.rb")
-#   end
-#
-# The +rdoc+ object passed to the block is an RDoc::Task object. See the
-# attributes list for the RDoc::Task class for available customization options.
-#
-# == Specifying different task names
-#
-# You may wish to give the task a different name, such as if you are
-# generating two sets of documentation.  For instance, if you want to have a
-# development set of documentation including private methods:
-#
-#   gem 'rdoc'
-#   require 'rdoc/task'
-#
-#   RDoc::Task.new :rdoc_dev do |rdoc|
-#     rdoc.main = "README.doc"
-#     rdoc.rdoc_files.include("README.rdoc", "lib/**/*.rb")
-#     rdoc.options << "--all"
-#   end
-#
-# The tasks would then be named :<em>rdoc_dev</em>,
-# :clobber_<em>rdoc_dev</em>, and :re<em>rdoc_dev</em>.
-#
-# If you wish to have completely different task names, then pass a Hash as
-# first argument. With the <tt>:rdoc</tt>, <tt>:clobber_rdoc</tt> and
-# <tt>:rerdoc</tt> options, you can customize the task names to your liking.
-#
-# For example:
-#
-#   gem 'rdoc'
-#   require 'rdoc/task'
-#
-#   RDoc::Task.new(:rdoc => "rdoc", :clobber_rdoc => "rdoc:clean",
-#                  :rerdoc => "rdoc:force")
-#
-# This will create the tasks <tt>:rdoc</tt>, <tt>:rdoc:clean</tt> and
-# <tt>:rdoc:force</tt>.

-    #   the search parameter.  This is either an Integer, which
-    #   will be used to find the index'th child Element, or an XPath,
-    #   which will be used to search for the Element.  <em>Because
-    #   of the nature of XPath searches, any element in the connected XML
-    #   document can be fetched through any other element.</em>  <b>The
-    #   Integer index is 1-based, not 0-based.</b>  This means that the first
-    #   child element is at index 1, not 0, and the +n+th element is at index
-    #   +n+, not <tt>n-1</tt>.  This is because XPath indexes element children

-##
-# = RSS reading and writing
-#
-# Really Simple Syndication (RSS) is a family of formats that describe 'feeds,'
-# specially constructed XML documents that allow an interested person to
-# subscribe and receive updates from a particular web service. This portion of
-# the standard library provides tooling to read and create these feeds.
-#
-# The standard library supports RSS 0.91, 1.0, 2.0, and Atom, a related format.
-# Here are some links to the standards documents for these formats:
-#
-# * RSS
-#   * 0.9.1[http://www.rssboard.org/rss-0-9-1-netscape]
-#   * 1.0[http://web.resource.org/rss/1.0/]
-#   * 2.0[http://www.rssboard.org/rss-specification]
-# * Atom[http://tools.ietf.org/html/rfc4287]
-#
-# == Consuming RSS
-#
-# If you'd like to read someone's RSS feed with your Ruby code, you've come to
-# the right place. It's really easy to do this, but we'll need the help of
-# open-uri:
-#
-#   require 'rss'
-#   require 'open-uri'
-#
-#   url = 'http://www.ruby-lang.org/en/feeds/news.rss'
-#   open(url) do |rss|
-#     feed = RSS::Parser.parse(rss)
-#     puts "Title: #{feed.channel.title}"
-#     feed.items.each do |item|
-#       puts "Item: #{item.title}"
-#     end
-#   end
-#
-# As you can see, the workhorse is RSS::Parser#parse, which takes the source of
-# the feed and a parameter that performs validation on the feed. We get back an
-# object that has all of the data from our feed, accessible through methods.
-# This example shows getting the title out of the channel element, and looping
-# through the list of items.
-#
-# == Producing RSS
-#
-# Producing our own RSS feeds is easy as well. Let's make a very basic feed:
-#
-#   require "rss"
-#
-#   rss = RSS::Maker.make("atom") do |maker|
-#     maker.channel.author = "matz"
-#     maker.channel.updated = Time.now.to_s
-#     maker.channel.about = "http://www.ruby-lang.org/en/feeds/news.rss"
-#     maker.channel.title = "Example Feed"
-#
-#     maker.items.new_item do |item|
-#       item.link = "http://www.ruby-lang.org/en/news/2010/12/25/ruby-1-9-2-p136-is-released/"
-#       item.title = "Ruby 1.9.2-p136 is released"
-#       item.updated = Time.now.to_s
-#     end
-#   end
-#
-#   puts rss
-#
-# As you can see, this is a very Builder-like DSL. This code will spit out an
-# Atom feed with one item. If we needed a second item, we'd make another block
-# with maker.items.new_item and build a second one.

-#
-# == RubyGems Plugins
-#
-# As of RubyGems 1.3.2, RubyGems will load plugins installed in gems or
-# $LOAD_PATH.  Plugins must be named 'rubygems_plugin' (.rb, .so, etc) and
-# placed at the root of your gem's #require_path.  Plugins are discovered via
-# Gem::find_files then loaded.  Take care when implementing a plugin as your
-# plugin file may be loaded multiple times if multiple versions of your gem
-# are installed.
-#
-# For an example plugin, see the graph gem which adds a `gem graph` command.
-#
-# == RubyGems Defaults, Packaging
-#
-# RubyGems defaults are stored in rubygems/defaults.rb.  If you're packaging
-# RubyGems or implementing Ruby you can change RubyGems' defaults.
-#
-# For RubyGems packagers, provide lib/rubygems/operating_system.rb and
-# override any defaults from lib/rubygems/defaults.rb.
-#
-# For Ruby implementers, provide lib/rubygems/#{RUBY_ENGINE}.rb and override
-# any defaults from lib/rubygems/defaults.rb.
-#
-# If you need RubyGems to perform extra work on install or uninstall, your
-# defaults override file can set pre and post install and uninstall hooks.
-# See Gem::pre_install, Gem::pre_uninstall, Gem::post_install,
-# Gem::post_uninstall.
-#
-# == Bugs
-#
-# You can submit bugs to the
-# {RubyGems bug tracker}[http://rubyforge.org/tracker/?atid=575&group_id=126]
-# on RubyForge

-  PLATFORMS = <<-'EOF'
-RubyGems platforms are composed of three parts, a CPU, an OS, and a
-version.  These values are taken from values in rbconfig.rb.  You can view
-your current platform by running `gem environment`.
-
-RubyGems matches platforms as follows:
-
-  * The CPU must match exactly, unless one of the platforms has
-    "universal" as the CPU.
-  * The OS must match exactly.
-  * The versions must match exactly unless one of the versions is nil.
-
-For commands that install, uninstall and list gems, you can override what
-RubyGems thinks your platform is with the --platform option.  The platform
-you pass must match "#{cpu}-#{os}" or "#{cpu}-#{os}-#{version}".  On mswin
-platforms, the version is the compiler version, not the OS version.  (Ruby
-compiled with VC6 uses "60" as the compiler version, VC8 uses "80".)
-
-Example platforms:
-
-  x86-freebsd        # Any FreeBSD version on an x86 CPU
-  universal-darwin-8 # Darwin 8 only gems that run on any CPU
-  x86-mswin32-80     # Windows gems compiled with VC8
-
-When building platform gems, set the platform in the gem specification to
-Gem::Platform::CURRENT.  This will correctly mark the gem with your ruby's
-platform.

-The install command installs local or remote gem into a gem repository.
-
-For gems with executables ruby installs a wrapper file into the executable
-directory by default.  This can be overridden with the --no-wrappers option.
-The wrapper allows you to choose among alternate gem versions using _version_.
-
-For example `rake _0.7.3_ --version` will run rake version 0.7.3 if a newer
-version is also installed.
-
-If an extension fails to compile during gem installation the gem
-specification is not written out, but the gem remains unpacked in the
-repository.  You may need to specify the path to the library's headers and
-libraries to continue.  You can do this by adding a -- between RubyGems'
-options and the extension's build options:
-
-  $ gem install some_extension_gem
-  [build fails]
-  Gem files will remain installed in \\
-  /path/to/gems/some_extension_gem-1.0 for inspection.
-  Results logged to /path/to/gems/some_extension_gem-1.0/gem_make.out

-  [build succeeds]
-  $ gem list some_extension_gem
-
-  *** LOCAL GEMS ***
-
-  some_extension_gem (1.0)

-  $ gem install some_extension_gem
-  [build fails]
-  Gem files will remain installed in \\

-  # the string.  The string IO approach was used for versions of ZLib before
-  # 1.2.1 to avoid buffer errors on windows machines.  Then we found that
-  # errors happened with 1.2.1 as well, so we changed the condition.  Then
-  # we discovered errors occurred with versions as late as 1.2.3.  At this
-  # point (after some benchmarking to show we weren't seriously crippling
-  # the unpacking speed) we threw our hands in the air and declared that
-  # this method would use the String IO approach on all platforms at all
-  # times.  And that's the way it is.
-  #
-  # Revisited.  Here's the beginning of the long story.
-  # http://osdir.com/ml/lang.ruby.gems.devel/2007-06/msg00045.html
-  #
-  # StringIO wraping has never worked as a workaround by definition.  Skipping
-  # initial 10 bytes and passing -MAX_WBITS to Zlib::Inflate luckily works as
-  # gzip reader, but it only works if the GZip header is 10 bytes long (see
-  # below) and it does not check inflated stream consistency (CRC value in the
-  # Gzip trailer.)
-  #
-  #   RubyGems generated Gzip Header: 10 bytes
-  #     magic(2) + method(1) + flag(1) + mtime(4) + exflag(1) + os(1) +
-  #     orig_name(0) + comment(0)
-  #
-  # Ideally, it must return a GZipReader without meaningless buffering.  We
-  # have lots of CRuby committers around so let's fix windows build when we
-  # received an error.

-#
-# == Overview
-#
-# Gem::Security implements cryptographic signatures in RubyGems.  The section
-# below is a step-by-step guide to using signed gems and generating your own.
-#
-# == Walkthrough
-#
-# In order to start signing your gems, you'll need to build a private key and
-# a self-signed certificate.  Here's how:
-#
-#   # build a private key and certificate for gemmaster@example.com
-#   $ gem cert --build gemmaster@example.com
-#
-# This could take anywhere from 5 seconds to 10 minutes, depending on the
-# speed of your computer (public key algorithms aren't exactly the speediest
-# crypto algorithms in the world).  When it's finished, you'll see the files
-# "gem-private_key.pem" and "gem-public_cert.pem" in the current directory.
-#
-# First things first: take the "gem-private_key.pem" file and move it
-# somewhere private, preferably a directory only you have access to, a floppy
-# (yuck!), a CD-ROM, or something comparably secure.  Keep your private key
-# hidden; if it's compromised, someone can sign packages as you (note: PKI has
-# ways of mitigating the risk of stolen keys; more on that later).
-#
-# Now, let's sign an existing gem.  I'll be using my Imlib2-Ruby bindings, but
-# you can use whatever gem you'd like.  Open up your existing gemspec file and
-# add the following lines:
-#
-#   # signing key and certificate chain
-#   s.signing_key = '/mnt/floppy/gem-private_key.pem'
-#   s.cert_chain  = ['gem-public_cert.pem']
-#
-# (Be sure to replace "/mnt/floppy" with the ultra-secret path to your private
-# key).
-#
-# After that, go ahead and build your gem as usual.  Congratulations, you've
-# just built your first signed gem!  If you peek inside your gem file, you'll
-# see a couple of new files have been added:
-#
-#   $ tar tf tar tf Imlib2-Ruby-0.5.0.gem
-#   data.tar.gz
-#   data.tar.gz.sig
-#   metadata.gz
-#   metadata.gz.sig
-#
-# Now let's verify the signature.  Go ahead and install the gem, but add the
-# following options: "-P HighSecurity", like this:
-#
-#   # install the gem with using the security policy "HighSecurity"
-#   $ sudo gem install Imlib2-Ruby-0.5.0.gem -P HighSecurity
-#
-# The -P option sets your security policy -- we'll talk about that in just a
-# minute.  Eh, what's this?
-#
-#   Attempting local installation of 'Imlib2-Ruby-0.5.0.gem'
-#   ERROR:  Error installing gem Imlib2-Ruby-0.5.0.gem[.gem]: Couldn't
-#   verify data signature: Untrusted Signing Chain Root: cert =
-#   '/CN=gemmaster/DC=example/DC=com', error = 'path
-#   "/root/.rubygems/trust/cert-15dbb43a6edf6a70a85d4e784e2e45312cff7030.pem"
-#   does not exist'
-#
-# The culprit here is the security policy.  RubyGems has several different
-# security policies.  Let's take a short break and go over the security
-# policies.  Here's a list of the available security policies, and a brief
-# description of each one:
-#
-# * NoSecurity - Well, no security at all.  Signed packages are treated like
-#   unsigned packages.
-# * LowSecurity - Pretty much no security.  If a package is signed then
-#   RubyGems will make sure the signature matches the signing
-#   certificate, and that the signing certificate hasn't expired, but
-#   that's it.  A malicious user could easily circumvent this kind of
-#   security.
-# * MediumSecurity - Better than LowSecurity and NoSecurity, but still
-#   fallible.  Package contents are verified against the signing
-#   certificate, and the signing certificate is checked for validity,
-#   and checked against the rest of the certificate chain (if you don't
-#   know what a certificate chain is, stay tuned, we'll get to that).
-#   The biggest improvement over LowSecurity is that MediumSecurity
-#   won't install packages that are signed by untrusted sources.
-#   Unfortunately, MediumSecurity still isn't totally secure -- a
-#   malicious user can still unpack the gem, strip the signatures, and
-#   distribute the gem unsigned.
-# * HighSecurity - Here's the bugger that got us into this mess.
-#   The HighSecurity policy is identical to the MediumSecurity policy,
-#   except that it does not allow unsigned gems.  A malicious user
-#   doesn't have a whole lot of options here; he can't modify the
-#   package contents without invalidating the signature, and he can't
-#   modify or remove signature or the signing certificate chain, or
-#   RubyGems will simply refuse to install the package.  Oh well, maybe
-#   he'll have better luck causing problems for CPAN users instead :).
-#
-# So, the reason RubyGems refused to install our shiny new signed gem was
-# because it was from an untrusted source.  Well, my code is infallible
-# (hah!), so I'm going to add myself as a trusted source.
-#
-# Here's how:
-#
-#     # add trusted certificate
-#     gem cert --add gem-public_cert.pem
-#
-# I've added my public certificate as a trusted source.  Now I can install
-# packages signed my private key without any hassle.  Let's try the install
-# command above again:
-#
-#   # install the gem with using the HighSecurity policy (and this time
-#   # without any shenanigans)
-#   $ sudo gem install Imlib2-Ruby-0.5.0.gem -P HighSecurity
-#
-# This time RubyGems should accept your signed package and begin installing.
-# While you're waiting for RubyGems to work it's magic, have a look at some of
-# the other security commands:
-#
-#   Usage: gem cert [options]
-#
-#   Options:
-#     -a, --add CERT          Add a trusted certificate.
-#     -l, --list              List trusted certificates.
-#     -r, --remove STRING     Remove trusted certificates containing STRING.
-#     -b, --build EMAIL_ADDR  Build private key and self-signed certificate
-#                             for EMAIL_ADDR.
-#     -C, --certificate CERT  Certificate for --sign command.
-#     -K, --private-key KEY   Private key for --sign command.
-#     -s, --sign NEWCERT      Sign a certificate with my key and certificate.
-#
-# (By the way, you can pull up this list any time you'd like by typing "gem
-# cert --help")
-#
-# Hmm.  We've already covered the "--build" option, and the "--add", "--list",
-# and "--remove" commands seem fairly straightforward; they allow you to add,
-# list, and remove the certificates in your trusted certificate list.  But
-# what's with this "--sign" option?
-#
-# To answer that question, let's take a look at "certificate chains", a
-# concept I mentioned earlier.  There are a couple of problems with
-# self-signed certificates: first of all, self-signed certificates don't offer
-# a whole lot of security.  Sure, the certificate says Yukihiro Matsumoto, but
-# how do I know it was actually generated and signed by matz himself unless he
-# gave me the certificate in person?
-#
-# The second problem is scalability.  Sure, if there are 50 gem authors, then
-# I have 50 trusted certificates, no problem.  What if there are 500 gem
-# authors?  1000?  Having to constantly add new trusted certificates is a
-# pain, and it actually makes the trust system less secure by encouraging
-# RubyGems users to blindly trust new certificates.
-#
-# Here's where certificate chains come in.  A certificate chain establishes an
-# arbitrarily long chain of trust between an issuing certificate and a child
-# certificate.  So instead of trusting certificates on a per-developer basis,
-# we use the PKI concept of certificate chains to build a logical hierarchy of
-# trust.  Here's a hypothetical example of a trust hierarchy based (roughly)
-# on geography:
-#
-#
-#                         --------------------------
-#                         | rubygems@rubyforge.org |
-#                         --------------------------
-#                                     |
-#                   -----------------------------------
-#                   |                                 |
-#       ----------------------------    -----------------------------
-#       | seattle.rb@zenspider.com |    | dcrubyists@richkilmer.com |
-#       ----------------------------    -----------------------------
-#            |                |                 |             |
-#     ---------------   ----------------   -----------   --------------
-#     | alf@seattle |   | bob@portland |   | pabs@dc |   | tomcope@dc |
-#     ---------------   ----------------   -----------   --------------
-#
-#
-# Now, rather than having 4 trusted certificates (one for alf@seattle,
-# bob@portland, pabs@dc, and tomecope@dc), a user could actually get by with 1
-# certificate: the "rubygems@rubyforge.org" certificate.  Here's how it works:
-#
-# I install "Alf2000-Ruby-0.1.0.gem", a package signed by "alf@seattle".  I've
-# never heard of "alf@seattle", but his certificate has a valid signature from
-# the "seattle.rb@zenspider.com" certificate, which in turn has a valid
-# signature from the "rubygems@rubyforge.org" certificate.  Voila!  At this
-# point, it's much more reasonable for me to trust a package signed by
-# "alf@seattle", because I can establish a chain to "rubygems@rubyforge.org",
-# which I do trust.
-#
-# And the "--sign" option allows all this to happen.  A developer creates
-# their build certificate with the "--build" option, then has their
-# certificate signed by taking it with them to their next regional Ruby meetup
-# (in our hypothetical example), and it's signed there by the person holding
-# the regional RubyGems signing certificate, which is signed at the next
-# RubyConf by the holder of the top-level RubyGems certificate.  At each point
-# the issuer runs the same command:
-#
-#   # sign a certificate with the specified key and certificate
-#   # (note that this modifies client_cert.pem!)
-#   $ gem cert -K /mnt/floppy/issuer-priv_key.pem -C issuer-pub_cert.pem
-#      --sign client_cert.pem
-#
-# Then the holder of issued certificate (in this case, our buddy
-# "alf@seattle"), can start using this signed certificate to sign RubyGems.
-# By the way, in order to let everyone else know about his new fancy signed
-# certificate, "alf@seattle" would change his gemspec file to look like this:
-#
-#   # signing key (still kept in an undisclosed location!)
-#   s.signing_key = '/mnt/floppy/alf-private_key.pem'
-#
-#   # certificate chain (includes the issuer certificate now too)
-#   s.cert_chain  = ['/home/alf/doc/seattlerb-public_cert.pem',
-#                    '/home/alf/doc/alf_at_seattle-public_cert.pem']
-#
-# Obviously, this RubyGems trust infrastructure doesn't exist yet.  Also, in
-# the "real world" issuers actually generate the child certificate from a
-# certificate request, rather than sign an existing certificate.  And our
-# hypothetical infrastructure is missing a certificate revocation system.
-# These are that can be fixed in the future...
-#
-# I'm sure your new signed gem has finished installing by now (unless you're
-# installing rails and all it's dependencies, that is ;D).  At this point you
-# should know how to do all of these new and interesting things:
-#
-# * build a gem signing key and certificate
-# * modify your existing gems to support signing
-# * adjust your security policy
-# * modify your trusted certificate list
-# * sign a certificate
-#
-# If you've got any questions, feel free to contact me at the email address
-# below.  The next couple of sections
-#
-#
-# == Command-Line Options
-#
-# Here's a brief summary of the certificate-related command line options:
-#
-#   gem install
-#     -P, --trust-policy POLICY        Specify gem trust policy.
-#
-#   gem cert
-#     -a, --add CERT                   Add a trusted certificate.
-#     -l, --list                       List trusted certificates.
-#     -r, --remove STRING              Remove trusted certificates containing
-#                                      STRING.
-#     -b, --build EMAIL_ADDR           Build private key and self-signed
-#                                      certificate for EMAIL_ADDR.
-#     -C, --certificate CERT           Certificate for --sign command.
-#     -K, --private-key KEY            Private key for --sign command.
-#     -s, --sign NEWCERT               Sign a certificate with my key and
-#                                      certificate.
-#
-# A more detailed description of each options is available in the walkthrough
-# above.
-#
-# == Manually verifying signatures
-#
-# In case you don't trust RubyGems you can verify gem signatures manually:
-#
-# 1. Fetch and unpack the gem
-#
-#     gem fetch some_signed_gem
-#     tar -xf some_signed_gem-1.0.gem
-#
-# 2. Grab the public key from the gemspec
-#
-#     gem spec some_signed_gem-1.0.gem cert_chain | \
-#       ruby -pe 'sub(/^ +/, "")' > public_key.crt
-#
-# 3. Generate a SHA1 hash of the data.tar.gz
-#
-#     openssl dgst -sha1 < data.tar.gz > my.hash
-#
-# 4. Verify the signature
-#
-#     openssl rsautl -verify -inkey public_key.crt -certin \
-#       -in data.tar.gz.sig > verified.hash
-#
-# 5. Compare your hash to the verified hash
-#
-#     diff -s verified.hash my.hash
-#
-# 6. Repeat 5 and 6 with metadata.gz
-#
-# == OpenSSL Reference
-#
-# The .pem files generated by --build and --sign are just basic OpenSSL PEM
-# files.  Here's a couple of useful commands for manipulating them:
-#
-#   # convert a PEM format X509 certificate into DER format:
-#   # (note: Windows .cer files are X509 certificates in DER format)
-#   $ openssl x509 -in input.pem -outform der -out output.der
-#
-#   # print out the certificate in a human-readable format:
-#   $ openssl x509 -in input.pem -noout -text
-#
-# And you can do the same thing with the private key file as well:
-#
-#   # convert a PEM format RSA key into DER format:
-#   $ openssl rsa -in input_key.pem -outform der -out output_key.der
-#
-#   # print out the key in a human readable format:
-#   $ openssl rsa -in input_key.pem -noout -text
-#
-# == Bugs/TODO
-#
-# * There's no way to define a system-wide trust list.
-# * custom security policies (from a YAML file, etc)
-# * Simple method to generate a signed certificate request
-# * Support for OCSP, SCVP, CRLs, or some other form of cert
-#   status check (list is in order of preference)
-# * Support for encrypted private keys

-  # Can be used for quick navigation to the rdoc documentation.  You can then

-  # 'shortcut:rdoc' to http://localhost:8808/rdoc?q=%s template. Then you can
-  # directly open the ActionPack documentation by typing 'rdoc actionp'. If
-  # there are multiple hits for the search term, they are presented as a list
-  # with links.
-  #
-  # Search algorithm aims for an intuitive search:
-  # 1. first try to find the gems and documentation folders which name
-  #    starts with the search term
-  # 2. search for entries, that *contain* the search term
-  # 3. show all the gems
-  #
-  # If there is only one search hit, user is immediately redirected to the
-  # documentation for the particular gem, otherwise a list with results is
-  # shown.
-  #
-  # === Additional trick - install documentation for ruby core
-  #
-  # Note: please adjust paths accordingly use for example 'locate yaml.rb' and
-  # 'gem environment' to identify directories, that are specific for your
-  # local installation
-  #
-  # 1. install ruby sources
-  #      cd /usr/src
-  #      sudo apt-get source ruby
-  #
-  # 2. generate documentation
-  #      rdoc -o /usr/lib/ruby/gems/1.8/doc/core/rdoc \
-  #        /usr/lib/ruby/1.8 ruby1.8-1.8.7.72
-  #
-  # By typing 'rdoc core' you can now access the core documentation

-##
-# The Version class processes string versions into comparable
-# values. A version string should normally be a series of numbers
-# separated by periods. Each part (digits separated by periods) is
-# considered its own number, and these are used for sorting. So for
-# instance, 3.10 sorts higher than 3.2 because ten is greater than
-# two.
-#
-# If any part contains letters (currently only a-z are supported) then
-# that version is considered prerelease. Versions with a prerelease
-# part in the Nth part sort less than versions with N-1
-# parts. Prerelease parts are sorted alphabetically using the normal
-# Ruby string sorting rules. If a prerelease part contains both
-# letters and numbers, it will be broken into multiple parts to
-# provide expected sort behavior (1.0.a10 becomes 1.0.a.10, and is
-# greater than 1.0.a9).
-#
-# Prereleases sort between real releases (newest to oldest):
-#
-# 1. 1.0
-# 2. 1.0.b1
-# 3. 1.0.a.2
-# 4. 0.9
-#
-# == How Software Changes
-#
-# Users expect to be able to specify a version constraint that gives them
-# some reasonable expectation that new versions of a library will work with
-# their software if the version constraint is true, and not work with their
-# software if the version constraint is false.  In other words, the perfect
-# system will accept all compatible versions of the library and reject all
-# incompatible versions.
-#
-# Libraries change in 3 ways (well, more than 3, but stay focused here!).
-#
-# 1. The change may be an implementation detail only and have no effect on
-#    the client software.
-# 2. The change may add new features, but do so in a way that client software
-#    written to an earlier version is still compatible.
-# 3. The change may change the public interface of the library in such a way
-#    that old software is no longer compatible.
-#
-# Some examples are appropriate at this point.  Suppose I have a Stack class
-# that supports a <tt>push</tt> and a <tt>pop</tt> method.
-#
-# === Examples of Category 1 changes:
-#
-# * Switch from an array based implementation to a linked-list based
-#   implementation.
-# * Provide an automatic (and transparent) backing store for large stacks.
-#
-# === Examples of Category 2 changes might be:
-#
-# * Add a <tt>depth</tt> method to return the current depth of the stack.
-# * Add a <tt>top</tt> method that returns the current top of stack (without
-#   changing the stack).
-# * Change <tt>push</tt> so that it returns the item pushed (previously it
-#   had no usable return value).
-#
-# === Examples of Category 3 changes might be:
-#
-# * Changes <tt>pop</tt> so that it no longer returns a value (you must use
-#   <tt>top</tt> to get the top of the stack).
-# * Rename the methods to <tt>push_item</tt> and <tt>pop_item</tt>.
-#
-# == RubyGems Rational Versioning
-#
-# * Versions shall be represented by three non-negative integers, separated
-#   by periods (e.g. 3.1.4).  The first integers is the "major" version
-#   number, the second integer is the "minor" version number, and the third
-#   integer is the "build" number.
-#
-# * A category 1 change (implementation detail) will increment the build
-#   number.
-#
-# * A category 2 change (backwards compatible) will increment the minor
-#   version number and reset the build number.
-#
-# * A category 3 change (incompatible) will increment the major build number
-#   and reset the minor and build numbers.
-#
-# * Any "public" release of a gem should have a different version.  Normally
-#   that means incrementing the build number.  This means a developer can
-#   generate builds all day long for himself, but as soon as he/she makes a
-#   public release, the version must be updated.
-#
-# === Examples
-#
-# Let's work through a project lifecycle using our Stack example from above.
-#
-# Version 0.0.1:: The initial Stack class is release.
-# Version 0.0.2:: Switched to a linked=list implementation because it is
-#                 cooler.
-# Version 0.1.0:: Added a <tt>depth</tt> method.
-# Version 1.0.0:: Added <tt>top</tt> and made <tt>pop</tt> return nil
-#                 (<tt>pop</tt> used to return the  old top item).
-# Version 1.1.0:: <tt>push</tt> now returns the value pushed (it used it
-#                 return nil).
-# Version 1.1.1:: Fixed a bug in the linked list implementation.
-# Version 1.1.2:: Fixed a bug introduced in the last fix.
-#
-# Client A needs a stack with basic push/pop capability.  He writes to the
-# original interface (no <tt>top</tt>), so his version constraint looks
-# like:
-#
-#   gem 'stack', '~> 0.0'
-#
-# Essentially, any version is OK with Client A.  An incompatible change to
-# the library will cause him grief, but he is willing to take the chance (we
-# call Client A optimistic).
-#
-# Client B is just like Client A except for two things: (1) He uses the
-# <tt>depth</tt> method and (2) he is worried about future
-# incompatibilities, so he writes his version constraint like this:
-#
-#   gem 'stack', '~> 0.1'
-#
-# The <tt>depth</tt> method was introduced in version 0.1.0, so that version
-# or anything later is fine, as long as the version stays below version 1.0
-# where incompatibilities are introduced.  We call Client B pessimistic
-# because he is worried about incompatible future changes (it is OK to be
-# pessimistic!).
-#
-# == Preventing Version Catastrophe:
-#
-# From: http://blog.zenspider.com/2008/10/rubygems-howto-preventing-cata.html
-#
-# Let's say you're depending on the fnord gem version 2.y.z. If you
-# specify your dependency as ">= 2.0.0" then, you're good, right? What
-# happens if fnord 3.0 comes out and it isn't backwards compatible
-# with 2.y.z? Your stuff will break as a result of using ">=". The
-# better route is to specify your dependency with a "spermy" version
-# specifier. They're a tad confusing, so here is how the dependency
-# specifiers work:
-#
-#   Specification From  ... To (exclusive)
-#   ">= 3.0"      3.0   ... &infin;
-#   "~> 3.0"      3.0   ... 4.0
-#   "~> 3.0.0"    3.0.0 ... 3.1
-#   "~> 3.5"      3.5   ... 4.0
-#   "~> 3.5.0"    3.5.0 ... 3.6

-# scanf for Ruby
-#
-#--
-# $Release Version: 1.1.2 $
-# $Revision$
-# $Id$
-# $Author$
-#++
-#
-# == Description
-#
-# scanf is an implementation of the C function scanf(3), modified as necessary
-# for ruby compatibility.
-#
-# the methods provided are String#scanf, IO#scanf, and
-# Kernel#scanf. Kernel#scanf is a wrapper around STDIN.scanf.  IO#scanf
-# can be used on any IO stream, including file handles and sockets.
-# scanf can be called either with or without a block.
-#
-# Scanf scans an input string or stream according to a <b>format</b>, as
-# described below in Conversions, and returns an array of matches between
-# the format and the input.  The format is defined in a string, and is
-# similar (though not identical) to the formats used in Kernel#printf and
-# Kernel#sprintf.
-#
-# The format may contain <b>conversion specifiers</b>, which tell scanf
-# what form (type) each particular matched substring should be converted
-# to (e.g., decimal integer, floating point number, literal string,
-# etc.)  The matches and conversions take place from left to right, and
-# the conversions themselves are returned as an array.
-#
-# The format string may also contain characters other than those in the
-# conversion specifiers.  White space (blanks, tabs, or newlines) in the
-# format string matches any amount of white space, including none, in
-# the input.  Everything else matches only itself.
-#
-# Scanning stops, and scanf returns, when any input character fails to
-# match the specifications in the format string, or when input is
-# exhausted, or when everything in the format string has been
-# matched. All matches found up to the stopping point are returned in
-# the return array (or yielded to the block, if a block was given).
-#
-#
-# == Basic usage
-#
-#   require 'scanf'
-#
-#   # String#scanf and IO#scanf take a single argument, the format string
-#   array = a_string.scanf("%d%s")
-#   array = an_io.scanf("%d%s")
-#
-#   # Kernel#scanf reads from STDIN
-#   array = scanf("%d%s")
-#
-# == Block usage
-#
-# When called with a block, scanf keeps scanning the input, cycling back
-# to the beginning of the format string, and yields a new array of
-# conversions to the block every time the format string is matched
-# (including partial matches, but not including complete failures).  The
-# actual return value of scanf when called with a block is an array
-# containing the results of all the executions of the block.
-#
-#   str = "123 abc 456 def 789 ghi"
-#   str.scanf("%d%s") { |num,str| [ num * 2, str.upcase ] }
-#   # => [[246, "ABC"], [912, "DEF"], [1578, "GHI"]]
-#
-# == Conversions
-#
-# The single argument to scanf is a format string, which generally
-# includes one or more conversion specifiers.  Conversion specifiers
-# begin with the percent character ('%') and include information about
-# what scanf should next scan for (string, decimal number, single
-# character, etc.).
-#
-# There may be an optional maximum field width, expressed as a decimal
-# integer, between the % and the conversion.  If no width is given, a
-# default of `infinity' is used (with the exception of the %c specifier;
-# see below).  Otherwise, given a field width of <em>n</em> for a given
-# conversion, at most <em>n</em> characters are scanned in processing
-# that conversion.  Before conversion begins, most conversions skip
-# white space in the input string; this white space is not counted
-# against the field width.
-#
-# The following conversions are available.
-#
-# [%]
-#   Matches a literal `%'. That is, `%%' in the format string matches a
-#   single input `%' character. No conversion is done, and the resulting
-#   '%' is not included in the return array.
-#
-# [d]
-#   Matches an optionally signed decimal integer.
-#
-# [u]
-#   Same as d.
-#
-# [i]
-#   Matches an optionally signed integer. The integer is read in base
-#   16 if it begins with `0x' or `0X', in base 8 if it begins with `0',
-#   and in base 10 other- wise. Only characters that correspond to the
-#   base are recognized.
-#
-# [o]
-#   Matches an optionally signed octal integer.
-#
-# [x, X]
-#   Matches an optionally signed hexadecimal integer,
-#
-# [a, e, f, g, A, E, F, G]
-#   Matches an optionally signed floating-point number.
-#
-# [s]
-#   Matches a sequence of non-white-space character. The input string stops at
-#   white space or at the maximum field width, whichever occurs first.
-#
-# [c]
-#   Matches a single character, or a sequence of <em>n</em> characters if a
-#   field width of <em>n</em> is specified. The usual skip of leading white
-#   space is suppressed. To skip white space first, use an explicit space in
-#   the format.
-#
-# [[]
-#   Matches a nonempty sequence of characters from the specified set
-#   of accepted characters.  The usual skip of leading white space is
-#   suppressed.  This bracketed sub-expression is interpreted exactly like a
-#   character class in a Ruby regular expression.  (In fact, it is placed as-is
-#   in a regular expression.)  The matching against the input string ends with
-#   the appearance of a character not in (or, with a circumflex, in) the set,
-#   or when the field width runs out, whichever comes first.
-#
-# === Assignment suppression
-#
-# To require that a particular match occur, but without including the result
-# in the return array, place the <b>assignment suppression flag</b>, which is
-# the star character ('*'), immediately after the leading '%' of a format
-# specifier (just before the field width, if any).
-#
-# == scanf for Ruby compared with scanf in C
-#
-# scanf for Ruby is based on the C function scanf(3), but with modifications,
-# dictated mainly by the underlying differences between the languages.
-#
-# === Unimplemented flags and specifiers
-#
-# * The only flag implemented in scanf for Ruby is '<tt>*</tt>' (ignore
-#   upcoming conversion).  Many of the flags available in C versions of
-#   scanf(3) have to do with the type of upcoming pointer arguments, and are
-#   meaningless in Ruby.
-#
-# * The <tt>n</tt> specifier (store number of characters consumed so far in
-#   next pointer) is not implemented.
-#
-# * The <tt>p</tt> specifier (match a pointer value) is not implemented.
-#
-# === Altered specifiers
-#
-# [o, u, x, X]
-#   In scanf for Ruby, all of these specifiers scan for an optionally signed
-#   integer, rather than for an unsigned integer like their C counterparts.
-#
-# === Return values
-#
-# scanf for Ruby returns an array of successful conversions, whereas
-# scanf(3) returns the number of conversions successfully
-# completed. (See below for more details on scanf for Ruby's return
-# values.)
-#
-# == Return values
-#
-# Without a block, scanf returns an array containing all the conversions
-# it has found.  If none are found, scanf will return an empty array. An
-# unsuccessful match is never ignored, but rather always signals the end
-# of the scanning operation.  If the first unsuccessful match takes place
-# after one or more successful matches have already taken place, the
-# returned array will contain the results of those successful matches.
-#
-# With a block scanf returns a 'map'-like array of transformations from
-# the block -- that is, an array reflecting what the block did with each
-# yielded result from the iterative scanf operation.  (See "Block
-# usage", above.)
-#
-# == Current limitations and bugs
-#
-# When using IO#scanf under Windows, make sure you open your files in
-# binary mode:
-#
-#     File.open("filename", "rb")
-#
-# so that scanf can keep track of characters correctly.
-#
-# Support for character classes is reasonably complete (since it
-# essentially piggy-backs on Ruby's regular expression handling of
-# character classes), but users are advised that character class testing
-# has not been exhaustive, and that they should exercise some caution
-# in using any of the more complex and/or arcane character class
-# idioms.

-
-  # ==Technical notes
-  #
-  # ===Rationale behind scanf for Ruby
-  #
-  # The impetus for a scanf implementation in Ruby comes chiefly from the fact
-  # that existing pattern matching operations, such as Regexp#match and
-  # String#scan, return all results as strings, which have to be converted to
-  # integers or floats explicitly in cases where what's ultimately wanted are
-  # integer or float values.
-  #
-  # ===Design of scanf for Ruby
-  #
-  # scanf for Ruby is essentially a <format string>-to-<regular
-  # expression> converter.
-  #
-  # When scanf is called, a FormatString object is generated from the
-  # format string ("%d%s...") argument. The FormatString object breaks the
-  # format string down into atoms ("%d", "%5f", "blah", etc.), and from
-  # each atom it creates a FormatSpecifier object, which it
-  # saves.
-  #
-  # Each FormatSpecifier has a regular expression fragment and a "handler"
-  # associated with it. For example, the regular expression fragment
-  # associated with the format "%d" is "([-+]?\d+)", and the handler
-  # associated with it is a wrapper around String#to_i. scanf itself calls
-  # FormatString#match, passing in the input string. FormatString#match
-  # iterates through its FormatSpecifiers; for each one, it matches the
-  # corresponding regular expression fragment against the string. If
-  # there's a match, it sends the matched string to the handler associated
-  # with the FormatSpecifier.
-  #
-  # Thus, to follow up the "%d" example: if "123" occurs in the input
-  # string when a FormatSpecifier consisting of "%d" is reached, the "123"
-  # will be matched against "([-+]?\d+)", and the matched string will be
-  # rendered into an integer by a call to to_i.
-  #
-  # The rendered match is then saved to an accumulator array, and the
-  # input string is reduced to the post-match substring. Thus the string
-  # is "eaten" from the left as the FormatSpecifiers are applied in
-  # sequence.  (This is done to a duplicate string; the original string is
-  # not altered.)
-  #
-  # As soon as a regular expression fragment fails to match the string, or
-  # when the FormatString object runs out of FormatSpecifiers, scanning
-  # stops and results accumulated so far are returned in an array.

-# == Overview
-#
-# This library provides the Set class, which deals with a collection
-# of unordered values with no duplicates.  It is a hybrid of Array's
-# intuitive inter-operation facilities and Hash's fast lookup.  If you
-# need to keep values ordered, use the SortedSet class.
-#
-# The method +to_set+ is added to Enumerable for convenience.
-#
-# See the Set and SortedSet documentation for examples of usage.
-
-
-#
-# Set implements a collection of unordered values with no duplicates.
-# This is a hybrid of Array's intuitive inter-operation facilities and
-# Hash's fast lookup.
-#
-# The equality of each couple of elements is determined according to
-# Object#eql? and Object#hash, since Set uses Hash as storage.
-#
-# Set is easy to use with Enumerable objects (implementing +each+).
-# Most of the initializer methods and binary operators accept generic
-# Enumerable objects besides sets and arrays.  An Enumerable object
-# can be converted to Set using the +to_set+ method.
-#
-# == Example
-#
-#   require 'set'
-#   s1 = Set.new [1, 2]                   # -> #<Set: {1, 2}>
-#   s2 = [1, 2].to_set                    # -> #<Set: {1, 2}>
-#   s1 == s2                              # -> true
-#   s1.add("foo")                         # -> #<Set: {1, 2, "foo"}>
-#   s1.merge([2, 6])                      # -> #<Set: {6, 1, 2, "foo"}>
-#   s1.subset? s2                         # -> false
-#   s2.subset? s1                         # -> true

-# The Singleton module implements the Singleton pattern.
-#
-# == Usage
-#
-# To use Singleton, include the module in your class.
-#
-#    class Klass
-#       include Singleton
-#       # ...
-#    end
-#
-# This ensures that only one instance of Klass can be created.
-#
-#      a,b  = Klass.instance, Klass.instance
-#
-#      a == b
-#      # => true
-#
-#      Klass.new
-#      # => NoMethodError - new is private ...
-#
-# The instance is created at upon the first call of Klass.instance().
-#
-#      class OtherKlass
-#        include Singleton
-#        # ...
-#      end
-#
-#      ObjectSpace.each_object(OtherKlass){}
-#      # => 0
-#
-#      OtherKlass.instance
-#      ObjectSpace.each_object(OtherKlass){}
-#      # => 1
-#
-#
-# This behavior is preserved under inheritance and cloning.
-#
-# == Implementation
-#
-# This above is achieved by:
-#
-# *  Making Klass.new and Klass.allocate private.
-#
-# *  Overriding Klass.inherited(sub_klass) and Klass.clone() to ensure that the
-#    Singleton properties are kept when inherited and cloned.
-#
-# *  Providing the Klass.instance() method that returns the same object each
-#    time it is called.
-#
-# *  Overriding Klass._load(str) to call Klass.instance().
-#
-# *  Overriding Klass#clone and Klass#dup to raise TypeErrors to prevent
-#    cloning or duping.
-#
-# == Singleton and Marshal
-#
-# By default Singleton's #_dump(depth) returns the empty string. Marshalling by
-# default will strip state information, e.g. instance variables and taint
-# state, from the instance. Classes using Singleton can provide custom
-# _load(str) and _dump(depth) methods to retain some of the previous state of
-# the instance.
-#
-#    require 'singleton'
-#
-#    class Example
-#      include Singleton
-#      attr_accessor :keep, :strip
-#      def _dump(depth)
-#        # this strips the @strip information from the instance
-#        Marshal.dump(@keep, depth)
-#      end
-#
-#      def self._load(str)
-#        instance.keep = Marshal.load(str)
-#        instance
-#      end
-#    end
-#
-#    a = Example.instance
-#    a.keep = "keep this"
-#    a.strip = "get rid of this"
-#    a.taint
-#
-#    stored_state = Marshal.dump(a)
-#
-#    a.keep = nil
-#    a.strip = nil
-#    b = Marshal.load(stored_state)
-#    p a == b  #  => true
-#    p a.keep  #  => "keep this"
-#    p a.strip #  => nil

-# tempfile - manipulates temporary files

-# $Id$

-require 'delegate'
-require 'tmpdir'
-require 'thread'
-
-# A utility class for managing temporary files. When you create a Tempfile
-# object, it will create a temporary file with a unique filename. A Tempfile
-# objects behaves just like a File object, and you can perform all the usual
-# file operations on it: reading data, writing data, changing its permissions,
-# etc. So although this class does not explicitly document all instance methods
-# supported by File, you can in fact call any File instance method on a
-# Tempfile object.
-#
-# == Synopsis
-#
-#   require 'tempfile'
-#
-#   file = Tempfile.new('foo')
-#   file.path      # => A unique filename in the OS's temp directory,
-#                  #    e.g.: "/tmp/foo.24722.0"
-#                  #    This filename contains 'foo' in its basename.
-#   file.write("hello world")
-#   file.rewind
-#   file.read      # => "hello world"
-#   file.close
-#   file.unlink    # deletes the temp file
-#
-# == Good practices
-#
-# === Explicit close
-#
-# When a Tempfile object is garbage collected, or when the Ruby interpreter
-# exits, its associated temporary file is automatically deleted. This means
-# that's it's unnecessary to explicitly delete a Tempfile after use, though
-# it's good practice to do so: not explicitly deleting unused Tempfiles can
-# potentially leave behind large amounts of tempfiles on the filesystem
-# until they're garbage collected. The existence of these temp files can make
-# it harder to determine a new Tempfile filename.
-#
-# Therefore, one should always call #unlink or close in an ensure block, like
-# this:
-#
-#   file = Tempfile.new('foo')
-#   begin
-#      ...do something with file...
-#   ensure
-#      file.close
-#      file.unlink   # deletes the temp file
-#   end
-#
-# === Unlink after creation
-#
-# On POSIX systems, it's possible to unlink a file right after creating it,
-# and before closing it. This removes the filesystem entry without closing
-# the file handle, so it ensures that only the processes that already had
-# the file handle open can access the file's contents. It's strongly
-# recommended that you do this if you do not want any other processes to
-# be able to read from or write to the Tempfile, and you do not need to
-# know the Tempfile's filename either.
-#
-# For example, a practical use case for unlink-after-creation would be this:
-# you need a large byte buffer that's too large to comfortably fit in RAM,
-# e.g. when you're writing a web server and you want to buffer the client's
-# file upload data.
-#
-# Please refer to #unlink for more information and a code example.
-#
-# == Minor notes
-#
-# Tempfile's filename picking method is both thread-safe and inter-process-safe:
-# it guarantees that no other threads or processes will pick the same filename.
-#
-# Tempfile itself however may not be entirely thread-safe. If you access the
-# same Tempfile object from multiple threads then you should protect it with a
-# mutex.

-  #
-  # Creates a temporary file with permissions 0600 (= only readable and
-  # writable by the owner) and opens it with mode "w+".
-  #
-  # The +basename+ parameter is used to determine the name of the
-  # temporary file. You can either pass a String or an Array with
-  # 2 String elements. In the former form, the temporary file's base
-  # name will begin with the given string. In the latter form,
-  # the temporary file's base name will begin with the array's first
-  # element, and end with the second element. For example:
-  #
-  #   file = Tempfile.new('hello')
-  #   file.path  # => something like: "/tmp/hello2843-8392-92849382--0"
-  #
-  #   # Use the Array form to enforce an extension in the filename:
-  #   file = Tempfile.new(['hello', '.jpg'])
-  #   file.path  # => something like: "/tmp/hello2843-8392-92849382--0.jpg"
-  #
-  # The temporary file will be placed in the directory as specified
-  # by the +tmpdir+ parameter. By default, this is +Dir.tmpdir+.
-  # When $SAFE > 0 and the given +tmpdir+ is tainted, it uses
-  # '/tmp' as the temporary directory. Please note that ENV values
-  # are tainted by default, and +Dir.tmpdir+'s return value might
-  # come from environment variables (e.g. <tt>$TMPDIR</tt>).
-  #
-  #   file = Tempfile.new('hello', '/home/aisaka')
-  #   file.path  # => something like: "/home/aisaka/hello2843-8392-92849382--0"
-  #
-  # You can also pass an options hash. Under the hood, Tempfile creates
-  # the temporary file using +File.open+. These options will be passed to
-  # +File.open+. This is mostly useful for specifying encoding
-  # options, e.g.:
-  #
-  #   Tempfile.new('hello', '/home/aisaka', :encoding => 'ascii-8bit')
-  #
-  #   # You can also omit the 'tmpdir' parameter:
-  #   Tempfile.new('hello', :encoding => 'ascii-8bit')
-  #
-  # === Exceptions
-  #
-  # If Tempfile.new cannot find a unique filename within a limited
-  # number of tries, then it will raise an exception.

-#
-# == Introduction
-#
-# This library extends the Time class:
-# * conversion between date string and time object.
-#   * date-time defined by RFC 2822
-#   * HTTP-date defined by RFC 2616
-#   * dateTime defined by XML Schema Part 2: Datatypes (ISO 8601)
-#   * various formats handled by Date._parse (string to time only)
-#
-# == Design Issues
-#
-# === Specialized interface
-#
-# This library provides methods dedicated to special purposes:
-# * RFC 2822, RFC 2616 and XML Schema.
-# * They makes usual life easier.
-#
-# === Doesn't depend on strftime
-#
-# This library doesn't use +Time#strftime+.  Especially #rfc2822 doesn't depend
-# on +strftime+ because:
-#
-# * %a and %b are locale sensitive
-#
-#   Since they are locale sensitive, they may be replaced to
-#   invalid weekday/month name in some locales.
-#   Since ruby-1.6 doesn't invoke setlocale by default,
-#   the problem doesn't arise until some external library invokes setlocale.
-#   Ruby/GTK is the example of such library.
-#
-# * %z is not portable
-#
-#   %z is required to generate zone in date-time of RFC 2822
-#   but it is not portable.
-#
-# Note that +Time#strftime+ doesn't use +strftime()+ function in libc since Ruby 1.9.
-# This means +Time#strftime+ is locale-insensitive since Ruby 1.9.
-# The above statements are not valid now.
-#
-
-require 'date'

-#
-# Implements the extensions to the Time class that are described in the
-# documentation for the time.rb library.

-    # Parses +date+ using Date._parse and converts it to a Time object.

-    # If a block is given, the year described in +date+ is converted by the
-    # block.  For example:
-    #
-    #     Time.parse(...) {|y| 0 <= y && y < 100 ? (y >= 69 ? y + 1900 : y + 2000) : y}
-    #
-    # If the upper components of the given time are broken or missing, they are
-    # supplied with those of +now+.  For the lower components, the minimum
-    # values (1 or 0) are assumed if broken or missing.  For example:
-    #
-    #     # Suppose it is "Thu Nov 29 14:33:20 GMT 2001" now and
-    #     # your timezone is GMT:
-    #     now = Time.parse("Thu Nov 29 14:33:20 GMT 2001")
-    #     Time.parse("16:30", now)     #=> 2001-11-29 16:30:00 +0900
-    #     Time.parse("7/23", now)      #=> 2001-07-23 00:00:00 +0900
-    #     Time.parse("Aug 31", now)    #=> 2001-08-31 00:00:00 +0900
-    #     Time.parse("Aug 2000", now)  #=> 2000-08-01 00:00:00 +0900
-    #
-    # Since there are numerous conflicts among locally defined timezone
-    # abbreviations all over the world, this method is not made to
-    # understand all of them.  For example, the abbreviation "CST" is
-    # used variously as:
-    #
-    #     -06:00 in America/Chicago,
-    #     -05:00 in America/Havana,
-    #     +08:00 in Asia/Harbin,
-    #     +09:30 in Australia/Darwin,
-    #     +10:30 in Australia/Adelaide,
-    #     etc.
-    #
-    # Based on the fact, this method only understands the timezone
-    # abbreviations described in RFC 822 and the system timezone, in the
-    # order named. (i.e. a definition in RFC 822 overrides the system
-    # timezone definition.)  The system timezone is taken from
-    # <tt>Time.local(year, 1, 1).zone</tt> and
-    # <tt>Time.local(year, 7, 1).zone</tt>.
-    # If the extracted timezone abbreviation does not match any of them,
-    # it is ignored and the given time is regarded as a local time.

-    # ArgumentError is raised if Date._parse cannot extract information from
-    # +date+ or Time class cannot represent specified date.

-#   status = Timeout::timeout(5) {
-#     # Something that should be interrupted if it takes more than 5 seconds...
-#   }
-#
-# == Description
-#
-# Timeout provides a way to auto-terminate a potentially long-running
-# operation if it hasn't finished in a fixed amount of time.
-#
-# Previous versions didn't use a module for namespacing, however
-# #timeout is provided for backwards compatibility.  You
-# should prefer Timeout#timeout instead.

-# tsort.rb - provides a module for topological sorting and strongly connected components.
-#++
-#
-
-#
-# TSort implements topological sorting using Tarjan's algorithm for
-# strongly connected components.
-#
-# TSort is designed to be able to be used with any object which can be
-# interpreted as a directed graph.
-#
-# TSort requires two methods to interpret an object as a graph,
-# tsort_each_node and tsort_each_child.
-#
-# * tsort_each_node is used to iterate for all nodes over a graph.
-# * tsort_each_child is used to iterate for child nodes of a given node.
-#
-# The equality of nodes are defined by eql? and hash since
-# TSort uses Hash internally.
-#
-# == A Simple Example
-#
-# The following example demonstrates how to mix the TSort module into an
-# existing class (in this case, Hash). Here, we're treating each key in
-# the hash as a node in the graph, and so we simply alias the required
-# #tsort_each_node method to Hash's #each_key method. For each key in the
-# hash, the associated value is an array of the node's child nodes. This
-# choice in turn leads to our implementation of the required #tsort_each_child
-# method, which fetches the array of child nodes and then iterates over that
-# array using the user-supplied block.
-#
-#   require 'tsort'
-#
-#   class Hash
-#     include TSort
-#     alias tsort_each_node each_key
-#     def tsort_each_child(node, &block)
-#       fetch(node).each(&block)
-#     end
-#   end
-#
-#   {1=>[2, 3], 2=>[3], 3=>[], 4=>[]}.tsort
-#   #=> [3, 2, 1, 4]
-#
-#   {1=>[2], 2=>[3, 4], 3=>[2], 4=>[]}.strongly_connected_components
-#   #=> [[4], [2, 3], [1]]
-#
-# == A More Realistic Example
-#
-# A very simple `make' like tool can be implemented as follows:
-#
-#   require 'tsort'
-#
-#   class Make
-#     def initialize
-#       @dep = {}
-#       @dep.default = []
-#     end
-#
-#     def rule(outputs, inputs=[], &block)
-#       triple = [outputs, inputs, block]
-#       outputs.each {|f| @dep[f] = [triple]}
-#       @dep[triple] = inputs
-#     end
-#
-#     def build(target)
-#       each_strongly_connected_component_from(target) {|ns|
-#         if ns.length != 1
-#           fs = ns.delete_if {|n| Array === n}
-#           raise TSort::Cyclic.new("cyclic dependencies: #{fs.join ', '}")
-#         end
-#         n = ns.first
-#         if Array === n
-#           outputs, inputs, block = n
-#           inputs_time = inputs.map {|f| File.mtime f}.max
-#           begin
-#             outputs_time = outputs.map {|f| File.mtime f}.min
-#           rescue Errno::ENOENT
-#             outputs_time = nil
-#           end
-#           if outputs_time == nil ||
-#              inputs_time != nil && outputs_time <= inputs_time
-#             sleep 1 if inputs_time != nil && inputs_time.to_i == Time.now.to_i
-#             block.call
-#           end
-#         end
-#       }
-#     end
-#
-#     def tsort_each_child(node, &block)
-#       @dep[node].each(&block)
-#     end
-#     include TSort
-#   end
-#
-#   def command(arg)
-#     print arg, "\n"
-#     system arg
-#   end
-#
-#   m = Make.new
-#   m.rule(%w[t1]) { command 'date > t1' }
-#   m.rule(%w[t2]) { command 'date > t2' }
-#   m.rule(%w[t3]) { command 'date > t3' }
-#   m.rule(%w[t4], %w[t1 t3]) { command 'cat t1 t3 > t4' }
-#   m.rule(%w[t5], %w[t4 t2]) { command 'cat t4 t2 > t5' }
-#   m.build('t5')
-#
-# == Bugs
-#
-# * 'tsort.rb' is wrong name because this library uses
-#   Tarjan's algorithm for strongly connected components.
-#   Although 'strongly_connected_components.rb' is correct but too long.

-# URI is a module providing classes to handle Uniform Resource Identifiers
-# (RFC2396[http://tools.ietf.org/html/rfc2396])
-#
-# == Features
-#
-# * Uniform handling of handling URIs
-# * Flexibility to introduce custom URI schemes
-# * Flexibility to have an alternate URI::Parser (or just different patterns
-#   and regexp's)
-#
-# == Basic example
-#
-#   require 'uri'
-#
-#   uri = URI("http://foo.com/posts?id=30&limit=5#time=1305298413")
-#   #=> #<URI::HTTP:0x00000000b14880
-#         URL:http://foo.com/posts?id=30&limit=5#time=1305298413>
-#   uri.scheme
-#   #=> "http"
-#   uri.host
-#   #=> "foo.com"
-#   uri.path
-#   #=> "/posts"
-#   uri.query
-#   #=> "id=30&limit=5"
-#   uri.fragment
-#   #=> "time=1305298413"
-#
-#   uri.to_s
-#   #=> "http://foo.com/posts?id=30&limit=5#time=1305298413"
-#
-# == Adding custom URIs
-#
-#   module URI
-#     class RSYNC < Generic
-#       DEFAULT_PORT = 873
-#     end
-#     @@schemes['RSYNC'] = RSYNC
-#   end
-#   #=> URI::RSYNC
-#
-#   URI.scheme_list
-#   #=> {"FTP"=>URI::FTP, "HTTP"=>URI::HTTP, "HTTPS"=>URI::HTTPS,
-#        "LDAP"=>URI::LDAP, "LDAPS"=>URI::LDAPS, "MAILTO"=>URI::MailTo,
-#        "RSYNC"=>URI::RSYNC}
-#
-#   uri = URI("rsync://rsync.foo.com")
-#   #=> #<URI::RSYNC:0x00000000f648c8 URL:rsync://rsync.foo.com>

-##
-# = WEB server toolkit.
-#
-# WEBrick is an HTTP server toolkit that can be configured as an HTTPS server,
-# a proxy server, and a virtual-host server.  WEBrick features complete
-# logging of both server operations and HTTP access.  WEBrick supports both
-# basic and digest authentication in addition to algorithms not in RFC 2617.
-#
-# A WEBrick servers can be composed of multiple WEBrick servers or servlets to
-# provide differing behavior on a per-host or per-path basis.  WEBrick
-# includes servlets for handling CGI scripts, ERb pages, ruby blocks and
-# directory listings.
-#
-# WEBrick also includes tools for daemonizing a process and starting a process
-# at a higher privilege level and dropping permissions.
-#
-# == Starting an HTTP server
-#
-# To create a new WEBrick::HTTPServer that will listen to connections on port
-# 8000 and serve documents from the current user's public_html folder:
-#
-#   require 'webrick'
-#
-#   root = File.expand_path '~/public_html'
-#   server = WEBrick::HTTPServer.new :Port => 8000, :DocumentRoot => root
-#
-# To run the server you will need to provide a suitable shutdown hook as
-# starting the server blocks the current thread:
-#
-#   trap 'INT' do server.shutdown end
-#
-#   server.start
-#
-# == Custom Behavior
-#
-# The easiest way to have a server perform custom operations is through
-# WEBrick::HTTPServer#mount_proc.  The block given will be called with a
-# WEBrick::HTTPRequest with request info and a WEBrick::HTTPResponse which
-# must be filled in appropriately:
-#
-#   server.mount_proc '/' do |req, res|
-#     res.body = 'Hello, world!'
-#   end
-#
-# Remember that <tt>server.mount_proc</tt> must <tt>server.start</tt>.
-#
-# == Servlets
-#
-# Advanced custom behavior can be obtained through mounting a subclass of
-# WEBrick::HTTPServlet::AbstractServlet.  Servlets provide more modularity
-# when writing an HTTP server than mount_proc allows.  Here is a simple
-# servlet:
-#
-#   class Simple < WEBrick::HTTPServlet::AbstractServlet
-#     def do_GET request, response
-#       status, content_type, body = do_stuff_with request
-#
-#       response.status = 200
-#       response['Content-Type'] = 'text/plain'
-#       response.body = 'Hello, World!'
-#     end
-#   end
-#
-# To initialize the servlet you mount it on the server:
-#
-#   server.mount '/simple', Simple
-#
-# See WEBrick::HTTPServlet::AbstractServlet for more details.
-#
-# == Virtual Hosts
-#
-# A server can act as a virtual host for multiple host names.  After creating
-# the listening host, additional hosts that do not listen can be created and
-# attached as virtual hosts:
-#
-#   server = WEBrick::HTTPServer.new # ...
-#
-#   vhost = WEBrick::HTTPServer.new :ServerName => 'vhost.example',
-#                                   :DoNotListen => true, # ...
-#   vhost.mount '/', ...
-#
-#   server.virtual_host vhost
-#
-# If no +:DocumentRoot+ is provided and no servlets or procs are mounted on the
-# main server it will return 404 for all URLs.
-#
-# == HTTPS
-#
-# To create an HTTPS server you only need to enable SSL and provide an SSL
-# certificate name:
-#
-#   require 'webrick'
-#   require 'webrick/https'
-#
-#   cert_name = [
-#     %w[CN localhost],
-#   ]
-#
-#   server = WEBrick::HTTPServer.new(:Port => 8000,
-#                                    :SSLEnable => true,
-#                                    :SSLCertName => cert_name)
-#
-# This will start the server with a self-generated self-signed certificate.
-# The certificate will be changed every time the server is restarted.
-#
-# To create a server with a pre-determined key and certificate you can provide
-# them:
-#
-#   require 'webrick'
-#   require 'webrick/https'
-#   require 'openssl'
-#
-#   cert = OpenSSL::X509::Certificate.new File.read '/path/to/cert.pem'
-#   pkey = OpenSSL::PKey::RSA.new File.read '/path/to/pkey.pem'
-#
-#   server = WEBrick::HTTPServer.new(:Port => 8000,
-#                                    :SSLEnable => true,
-#                                    :SSLCertificate => cert,
-#                                    :SSLPrivateKey => pkey)
-#
-# == Proxy Server
-#
-# WEBrick can act as a proxy server:
-#
-#   require 'webrick'
-#   require 'webrick/httpproxy'
-#
-#   proxy = WEBrick::HTTPProxyServer.new :Port => 8000
-#
-#   trap 'INT' do proxy.shutdown end
-#
-# Proxies may modifier the content of the response through the
-# +:ProxyContentHandler+ callback which will be invoked with the request and
-# respone after the remote content has been fetched.
-#
-# == Basic and Digest authentication
-#
-# WEBrick provides both Basic and Digest authentication for regular and proxy
-# servers.  See WEBrick::HTTPAuth, WEBrick::HTTPAuth::BasicAuth and
-# WEBrick::HTTPAuth::DigestAuth.
-#
-# == WEBrick as a Production Web Server
-#
-# WEBrick can be run as a production server for small loads.
-#
-# === Daemonizing
-#
-# To start a WEBrick server as a daemon simple run WEBrick::Daemon.start
-# before starting the server.
-#
-# === Dropping Permissions
-#
-# WEBrick can be started as one user to gain permission to bind to port 80 or
-# 443 for serving HTTP or HTTPS traffic then can drop these permissions for
-# regular operation.  To listen on all interfaces for HTTP traffic:
-#
-#   sockets = WEBrick::Utils.create_listeners nil, 80
-#
-# Then drop privileges:
-#
-#   WEBrick::Utils.su 'www'
-#
-# Then create a server that does not listen by default:
-#
-#   server = WEBrick::HTTPServer.new :DoNotListen => true, # ...
-#
-# Then overwrite the listening sockets with the port 80 sockets:
-#
-#   server.listeners.replace sockets
-#
-# === Logging
-#
-# WEBrick can separately log server operations and end-user access.  For
-# server operations:
-#
-#   log_file = File.open '/var/log/webrick.log', 'a+'
-#   log = WEBrick::Log.new log_file
-#
-# For user access logging:
-#
-#   access_log = [
-#     [log_file, WEBrick::AccessLog::COMBINED_LOG_FORMAT],
-#   ]
-#
-#   server = WEBrick::HTTPServer.new :Logger => log, :AccessLog => access_log
-#
-# See WEBrick::AccessLog for further log formats.
-#
-# === Log Rotation
-#
-# To rotate logs in WEBrick on a HUP signal (like syslogd can send), open the
-# log file in 'a+' mode (as above) and trap 'HUP' to reopen the log file:
-#
-#   trap 'HUP' do log_file.reopen '/path/to/webrick.log', 'a+'

-  # To enable authentication for requests in WEBrick you will need a user

-  #
-  #   config = { :Realm => 'DigestAuth example realm' }

-  #   htpasswd = WEBrick::HTTPAuth::Htpasswd.new 'my_password_file'

-  # The +:Realm+ is used to provide different access to different groups
-  # across several resources on a server.  Typically you'll need only one

-  #
-  #   def do_GET req, res
-  #     @authenticator.authenticate req, res

-== Author and Copyright
-
-Copyright (C) 2001-2004 by Michael Neumann (mailto:mneumann@ntecs.de)
-
-Released under the same term of license as Ruby.
-
-== Overview
-
-XMLRPC is a lightweight protocol that enables remote procedure calls over
-HTTP.  It is defined at http://www.xmlrpc.com.
-
-XMLRPC allows you to create simple distributed computing solutions that span
-computer languages.  Its distinctive feature is its simplicity compared to
-other approaches like SOAP and CORBA.
-
-The Ruby standard library package 'xmlrpc' enables you to create a server that
-implements remote procedures and a client that calls them.  Very little code
-is required to achieve either of these.
-
-== Example
-
-Try the following code.  It calls a standard demonstration remote procedure.
-
-  require 'xmlrpc/client'
-  require 'pp'
-
-  server = XMLRPC::Client.new2("http://xmlrpc-c.sourceforge.net/api/sample.php")
-  result = server.call("sample.sumAndDifference", 5, 3)
-  pp result
-
-== Documentation
-
-See http://www.ntecs.de/projects/xmlrpc4r.  There is plenty of detail there to
-use the client and implement a server.
-
-== Features of XMLRPC for Ruby
-
-* Extensions
-  * Introspection
-  * multiCall
-  * optionally nil values and integers larger than 32 Bit
-

-  * Expat (XMLStreamParser, XMLTreeParser)
-  * REXML (REXMLStreamParser)
-  * xml-scan (XMLScanStreamParser)
-  * Fastest parser is Expat's XMLStreamParser!
-
-* General
-  * possible to choose between XMLParser module (Expat wrapper) and REXML/NQXML (pure Ruby) parsers
-  * Marshalling Ruby objects to Hashs and reconstruct them later from a Hash
-  * SandStorm component architecture Client interface
-
-== Howto
-
-=== Client
-
-  require "xmlrpc/client"
-
-  # Make an object to represent the XML-RPC server.
-  server = XMLRPC::Client.new( "xmlrpc-c.sourceforge.net", "/api/sample.php")
-
-  # Call the remote server and get our result
-  result = server.call("sample.sumAndDifference", 5, 3)
-
-  sum = result["sum"]
-  difference = result["difference"]
-
-  puts "Sum: #{sum}, Difference: #{difference}"
-
-=== Client with XML-RPC fault-structure handling
-
-There are two possible ways, of handling a fault-structure:
-
-==== by catching a XMLRPC::FaultException exception
-
-  require "xmlrpc/client"
-
-  # Make an object to represent the XML-RPC server.
-  server = XMLRPC::Client.new( "xmlrpc-c.sourceforge.net", "/api/sample.php")
-
-  begin
-    # Call the remote server and get our result
-    result = server.call("sample.sumAndDifference", 5, 3)
-
-    sum = result["sum"]
-    difference = result["difference"]
-
-    puts "Sum: #{sum}, Difference: #{difference}"
-
-  rescue XMLRPC::FaultException => e
-    puts "Error: "
-    puts e.faultCode
-    puts e.faultString
-  end
-
-==== by calling "call2" which returns a boolean
-
-  require "xmlrpc/client"
-
-  # Make an object to represent the XML-RPC server.
-  server = XMLRPC::Client.new( "xmlrpc-c.sourceforge.net", "/api/sample.php")
-
-  # Call the remote server and get our result
-  ok, result = server.call2("sample.sumAndDifference", 5, 3)
-
-  if ok
-    sum = result["sum"]
-    difference = result["difference"]
-
-    puts "Sum: #{sum}, Difference: #{difference}"
-  else
-    puts "Error: "
-    puts result.faultCode
-    puts result.faultString
-  end
-
-=== Client using Proxy
-
-You can create a +Proxy+ object onto which you can call methods. This way it
-looks nicer. Both forms, _call_ and _call2_ are supported through _proxy_ and
-<i>proxy2</i>.  You can additionally give arguments to the Proxy, which will be
-given to each XML-RPC call using that Proxy.
-
-  require "xmlrpc/client"
-
-  # Make an object to represent the XML-RPC server.
-  server = XMLRPC::Client.new( "xmlrpc-c.sourceforge.net", "/api/sample.php")
-
-  # Create a Proxy object
-  sample = server.proxy("sample")
-
-  # Call the remote server and get our result
-  result = sample.sumAndDifference(5,3)
-
-  sum = result["sum"]
-  difference = result["difference"]
-
-  puts "Sum: #{sum}, Difference: #{difference}"
-
-=== CGI-based Server
-
-There are also two ways to define handler, the first is
-like C/PHP, the second like Java, of course both ways
-can be mixed:
-
-==== C/PHP-like (handler functions)
-
-  require "xmlrpc/server"
-
-  s = XMLRPC::CGIServer.new
-
-  s.add_handler("sample.sumAndDifference") do |a,b|
-    { "sum" => a + b, "difference" => a - b }
-  end
-
-  s.serve
-
-==== Java-like (handler classes)
-
-  require "xmlrpc/server"
-
-  s = XMLRPC::CGIServer.new
-
-  class MyHandler
-    def sumAndDifference(a, b)
-      { "sum" => a + b, "difference" => a - b }
-    end
-  end
-
-  # NOTE: Security Hole (read below)!!!
-  s.add_handler("sample", MyHandler.new)
-  s.serve
-
-
-To return a fault-structure you have to raise an FaultException e.g.:
-
-  raise XMLRPC::FaultException.new(3, "division by Zero")
-
-===== Security Note
-
-From Brian Candler:
-
-  Above code sample has an extremely nasty security hole, in that you can now call
-  any method of 'MyHandler' remotely, including methods inherited from Object
-  and Kernel! For example, in the client code, you can use
-
-    puts server.call("sample.send","`","ls")
-
-  (backtick being the method name for running system processes). Needless to
-  say, 'ls' can be replaced with something else.
-
-  The version which binds proc objects (or the version presented below in the next section)
-  doesn't have this problem, but people may be tempted to use the second version because it's
-  so nice and 'Rubyesque'. I think it needs a big red disclaimer.
-
-
-From Michael:
-
-A solution is to undef insecure methods or to use (({XMLRPC::iPIMethods})) as shown below:
-
-  class MyHandler
-    def sumAndDifference(a, b)
-      { "sum" => a + b, "difference" => a - b }
-    end
-  end
-
-  # ... server initialization ...
-
-  s.add_handler(XMLRPC::iPIMethods("sample"), MyHandler.new)
-
-  # ...
-
-This adds only public instance methods explicitly declared in class MyHandler
-(and not those inherited from any other class).
-
-==== With interface declarations
-
-Code sample from the book Ruby Developer's Guide:
-
-  require "xmlrpc/server"
-
-  class Num
-    INTERFACE = XMLRPC::interface("num") {
-      meth 'int add(int, int)', 'Add two numbers', 'add'
-      meth 'int div(int, int)', 'Divide two numbers'
-    }
-
-    def add(a, b) a + b end
-    def div(a, b) a / b end
-  end
-
-
-  s = XMLRPC::CGIServer.new
-  s.add_handler(Num::INTERFACE, Num.new)
-  s.serve
-
-=== Standalone server
-
-Same as CGI-based server, only that the line
-
-  server = XMLRPC::CGIServer.new
-
-must be changed to
-
-  server = XMLRPC::Server.new(8080)
-
-if you want a server listening on port 8080.
-The rest is the same.
-
-=== Choosing a different XML Parser or XML Writer
-
-The examples above all use the default parser (which is now since 1.8
-REXMLStreamParser) and a default XML writer.  If you want to use a different
-XML parser, then you have to call the <i>set_parser</i> method of
-<tt>XMLRPC::Client</tt> instances or instances of subclasses of
-<tt>XMLRPC::BasicServer</tt> or by editing xmlrpc/config.rb.
-
-Client Example:
-
-  # ...
-  server = XMLRPC::Client.new( "xmlrpc-c.sourceforge.net", "/api/sample.php")
-  server.set_parser(XMLRPC::XMLParser::XMLParser.new)
-  # ...
-
-Server Example:
-
-  # ...
-  s = XMLRPC::CGIServer.new
-  s.set_parser(XMLRPC::XMLParser::XMLStreamParser.new)
-  # ...
-
-or:
-
-  # ...
-  server = XMLRPC::Server.new(8080)
-  server.set_parser(XMLRPC::XMLParser::NQXMLParser.new)
-  # ...
-
-
-Note that XMLStreamParser is incredible faster (and uses less memory) than any
-other parser and scales well for large documents. For example for a 0.5 MB XML
-document with many tags, XMLStreamParser is ~350 (!) times faster than
-NQXMLTreeParser and still ~18 times as fast as XMLTreeParser.
-
-You can change the XML-writer by calling method <i>set_writer</i>.

-
-== Class Methods
---- XMLRPC::Base64.new( str, state = :dec )
-    Creates a new (({XMLRPC::Base64})) instance with string ((|str|)) as the
-    internal string. When ((|state|)) is (({:dec})) it assumes that the
-    string ((|str|)) is not in base64 format (perhaps already decoded),
-    otherwise if ((|state|)) is (({:enc})) it decodes ((|str|))
-    and stores it as the internal string.
-
---- XMLRPC::Base64.decode( str )
-    Decodes string ((|str|)) with base64 and returns that value.
-
---- XMLRPC::Base64.encode( str )
-    Encodes string ((|str|)) with base64 and returns that value.
-
-== Instance Methods
---- XMLRPC::Base64#decoded
-    Returns the internal string decoded.
-
---- XMLRPC::Base64#encoded

-After setting the connection-parameters with ((<XMLRPC::Client.new>)) which
-creates a new (({XMLRPC::Client})) instance, you can execute a remote procedure
-by sending the ((<call|XMLRPC::Client#call>)) or ((<call2|XMLRPC::Client#call2>))
-message to this new instance. The given parameters indicate which method to
-call on the remote-side and of course the parameters for the remote procedure.
-
-== Class Methods
---- XMLRPC::Client.new( host=nil, path=nil, port=nil, proxy_host=nil, proxy_port=nil, user=nil, password=nil, use_ssl=false, timeout =nil)
-    Creates an object which represents the remote XML-RPC server on the
-    given host ((|host|)). If the server is CGI-based, ((|path|)) is the
-    path to the CGI-script, which will be called, otherwise (in the
-    case of a standalone server) ((|path|)) should be (({"/RPC2"})).
-    ((|port|)) is the port on which the XML-RPC server listens.
-    If ((|proxy_host|)) is given, then a proxy server listening at
-    ((|proxy_host|)) is used. ((|proxy_port|)) is the port of the
-    proxy server.
-
-    Default values for ((|host|)), ((|path|)) and ((|port|)) are 'localhost', '/RPC2' and
-    '80' respectively using SSL '443'.
-
-    If ((|user|)) and ((|password|)) are given, each time a request is send,
-    a Authorization header is send. Currently only Basic Authentification is
-    implemented no Digest.
-
-    If ((|use_ssl|)) is set to (({true})), comunication over SSL is enabled.
-    Note, that you need the SSL package from RAA installed.
-
-    Parameter ((|timeout|)) is the time to wait for a XML-RPC response, defaults to 30.
-
---- XMLRPC::Client.new2( uri, proxy=nil, timeout=nil)
---- XMLRPC::Client.new_from_uri( uri, proxy=nil, timeout=nil)
-:   uri
-    URI specifying protocol (http or https), host, port, path, user and password.
-    Example: https://user:password@host:port/path
-
-:   proxy
-    Is of the form "host:port".
-
-:   timeout
-    Defaults to 30.
-
---- XMLRPC::Client.new3( hash={} )
---- XMLRPC::Client.new_from_hash( hash={} )
-    Parameter ((|hash|)) has following case-insensitive keys:
-    * host
-    * path
-    * port
-    * proxy_host
-    * proxy_port
-    * user
-    * password
-    * use_ssl
-    * timeout
-
-    Calls ((<XMLRPC::Client.new>)) with the corresponding values.
-
-== Instance Methods
---- XMLRPC::Client#call( method, *args )
-    Invokes the method named ((|method|)) with the parameters given by
-    ((|args|)) on the XML-RPC server.
-    The parameter ((|method|)) is converted into a (({String})) and should
-    be a valid XML-RPC method-name.
-    Each parameter of ((|args|)) must be of one of the following types,
-    where (({Hash})), (({Struct})) and (({Array})) can contain any of these listed ((:types:)):
-    * (({Fixnum})), (({Bignum}))
-    * (({TrueClass})), (({FalseClass})) ((({true})), (({false})))
-    * (({String})), (({Symbol}))
-    * (({Float}))
-    * (({Hash})), (({Struct}))
-    * (({Array}))
-    * (({Date})), (({Time})), (({XMLRPC::DateTime}))
-    * (({XMLRPC::Base64}))
-    * A Ruby object which class includes XMLRPC::Marshallable (only if Config::ENABLE_MARSHALLABLE is (({true}))).
-      That object is converted into a hash, with one additional key/value pair "___class___" which contains the class name
-      for restoring later that object.
-
-    The method returns the return-value from the RPC
-    ((-stands for Remote Procedure Call-)).
-    The type of the return-value is one of the above shown,
-    only that a (({Bignum})) is only allowed when it fits in 32-bit and
-    that a XML-RPC (('dateTime.iso8601')) type is always returned as
-    a ((<(({XMLRPC::DateTime}))|URL:datetime.html>)) object and
-    a (({Struct})) is never returned, only a (({Hash})), the same for a (({Symbol})), where
-    always a (({String})) is returned.
-    A (({XMLRPC::Base64})) is returned as a (({String})) from xmlrpc4r version 1.6.1 on.
-
-    If the remote procedure returned a fault-structure, then a
-    (({XMLRPC::FaultException})) exception is raised, which has two accessor-methods
-    (({faultCode})) and (({faultString})) of type (({Integer})) and (({String})).
-
---- XMLRPC::Client#call2( method, *args )
-    The difference between this method and ((<call|XMLRPC::Client#call>)) is, that
-    this method do ((*not*)) raise a (({XMLRPC::FaultException})) exception.
-    The method returns an array of two values. The first value indicates if
-    the second value is a return-value ((({true}))) or an object of type
-    (({XMLRPC::FaultException})).
-    Both are explained in ((<call|XMLRPC::Client#call>)).
-
-    Simple to remember: The "2" in "call2" denotes the number of values it returns.
-
---- XMLRPC::Client#multicall( *methods )
-    You can use this method to execute several methods on a XMLRPC server which supports
-    the multi-call extension.
-    Example:
-
-      s.multicall(
-        ['michael.add', 3, 4],
-        ['michael.sub', 4, 5]
-      )
-      # => [7, -1]
-
---- XMLRPC::Client#multicall2( *methods )
-    Same as ((<XMLRPC::Client#multicall>)), but returns like ((<XMLRPC::Client#call2>)) two parameters
-    instead of raising an (({XMLRPC::FaultException})).
-
---- XMLRPC::Client#proxy( prefix, *args )
-    Returns an object of class (({XMLRPC::Client::Proxy})), initialized with
-    ((|prefix|)) and ((|args|)). A proxy object returned by this method behaves
-    like ((<XMLRPC::Client#call>)), i.e. a call on that object will raise a
-    (({XMLRPC::FaultException})) when a fault-structure is returned by that call.
-
---- XMLRPC::Client#proxy2( prefix, *args )
-    Almost the same like ((<XMLRPC::Client#proxy>)) only that a call on the returned
-    (({XMLRPC::Client::Proxy})) object behaves like ((<XMLRPC::Client#call2>)), i.e.
-    a call on that object will return two parameters.
-
-
-
-
---- XMLRPC::Client#call_async(...)
---- XMLRPC::Client#call2_async(...)
---- XMLRPC::Client#multicall_async(...)
---- XMLRPC::Client#multicall2_async(...)
---- XMLRPC::Client#proxy_async(...)
---- XMLRPC::Client#proxy2_async(...)
-    In contrast to corresponding methods without "_async", these can be
-    called concurrently and use for each request a new connection, where the
-    non-asynchronous counterparts use connection-alive (one connection for all requests)
-    if possible.
-
-    Note, that you have to use Threads to call these methods concurrently.
-    The following example calls two methods concurrently:
-
-      Thread.new {
-        p client.call_async("michael.add", 4, 5)
-      }
-
-      Thread.new {
-        p client.call_async("michael.div", 7, 9)
-      }
-
-
---- XMLRPC::Client#timeout
---- XMLRPC::Client#user
---- XMLRPC::Client#password
-    Return the corresponding attributes.
-
---- XMLRPC::Client#timeout= (new_timeout)
---- XMLRPC::Client#user= (new_user)
---- XMLRPC::Client#password= (new_password)
-    Set the corresponding attributes.
-
-
---- XMLRPC::Client#set_writer( writer )
-    Sets the XML writer to use for generating XML output.
-    Should be an instance of a class from module (({XMLRPC::XMLWriter})).
-    If this method is not called, then (({XMLRPC::Config::DEFAULT_WRITER})) is used.
-
---- XMLRPC::Client#set_parser( parser )
-    Sets the XML parser to use for parsing XML documents.
-    Should be an instance of a class from module (({XMLRPC::XMLParser})).
-    If this method is not called, then (({XMLRPC::Config::DEFAULT_PARSER})) is used.
-
---- XMLRPC::Client#cookie
---- XMLRPC::Client#cookie= (cookieString)
-    Get and set the HTTP Cookie header.
-
---- XMLRPC::Client#http_header_extra= (additionalHeaders)
-    Set extra HTTP headers that are included in the request.
-
---- XMLRPC::Client#http_header_extra
-    Access the via ((<XMLRPC::Client#http_header_extra=>)) assigned header.
-
---- XMLRPC::Client#http_last_response
-    Returns the (({Net::HTTPResponse})) object of the last RPC.
-
-= XMLRPC::Client::Proxy
-== Synopsis
-    require "xmlrpc/client"
-
-    server = XMLRPC::Client.new("www.ruby-lang.org", "/RPC2", 80)
-
-    michael  = server.proxy("michael")
-    michael2 = server.proxy("michael", 4)
-
-    # both calls should return the same value '9'.
-    p michael.add(4,5)
-    p michael2.add(5)
-
-== Description
-Class (({XMLRPC::Client::Proxy})) makes XML-RPC calls look nicer!
-You can call any method onto objects of that class - the object handles
-(({method_missing})) and will forward the method call to a XML-RPC server.
-Don't use this class directly, but use instead method ((<XMLRPC::Client#proxy>)) or
-((<XMLRPC::Client#proxy2>)).
-
-== Class Methods
---- XMLRPC::Client::Proxy.new( server, prefix, args=[], meth=:call, delim="." )
-    Creates an object which provides (({method_missing})).
-
-    ((|server|)) must be of type (({XMLRPC::Client})), which is the XML-RPC server to be used
-    for a XML-RPC call. ((|prefix|)) and ((|delim|)) will be prepended to the methodname
-    called onto this object.
-
-    Parameter ((|meth|)) is the method (call, call2, call_async, call2_async) to use for
-    a RPC.
-
-    ((|args|)) are arguments which are automatically given
-    to every XML-RPC call before the arguments provides through (({method_missing})).
-
-== Instance Methods
-Every method call is forwarded to the XML-RPC server defined in ((<new|XMLRPC::Client::Proxy#new>)).
-
-Note: Inherited methods from class (({Object})) cannot be used as XML-RPC names, because they get around
-(({method_missing})).

-= XMLRPC::DateTime
-== Description
-This class is important to handle XMLRPC (('dateTime.iso8601')) values,
-correcly, because normal UNIX-dates (class (({Date}))) only handle dates
-from year 1970 on, and class (({Time})) handles dates without the time
-component. (({XMLRPC::DateTime})) is able to store a XMLRPC
-(('dateTime.iso8601')) value correctly.
-
-== Class Methods
---- XMLRPC::DateTime.new( year, month, day, hour, min, sec )
-    Creates a new (({XMLRPC::DateTime})) instance with the
-    parameters ((|year|)), ((|month|)), ((|day|)) as date and
-    ((|hour|)), ((|min|)), ((|sec|)) as time.
-    Raises (({ArgumentError})) if a parameter is out of range, or ((|year|)) is not
-    of type (({Integer})).
-
-== Instance Methods
---- XMLRPC::DateTime#year
---- XMLRPC::DateTime#month
---- XMLRPC::DateTime#day
---- XMLRPC::DateTime#hour
---- XMLRPC::DateTime#min
---- XMLRPC::DateTime#sec
-    Return the value of the specified date/time component.
-
---- XMLRPC::DateTime#mon
-    Alias for ((<XMLRPC::DateTime#month>)).
-
---- XMLRPC::DateTime#year=( value )
---- XMLRPC::DateTime#month=( value )
---- XMLRPC::DateTime#day=( value )
---- XMLRPC::DateTime#hour=( value )
---- XMLRPC::DateTime#min=( value )
---- XMLRPC::DateTime#sec=( value )
-    Set ((|value|)) as the new date/time component.
-    Raises (({ArgumentError})) if ((|value|)) is out of range, or in the case
-    of (({XMLRPC::DateTime#year=})) if ((|value|)) is not of type (({Integer})).
-
---- XMLRPC::DateTime#mon=( value )
-    Alias for ((<XMLRPC::DateTime#month=>)).
-
---- XMLRPC::DateTime#to_time
-    Return a (({Time})) object of the date/time which (({self})) represents.
-    If the (('year')) is below 1970, this method returns (({nil})),
-    because (({Time})) cannot handle years below 1970.
-    The used timezone is GMT.
-
---- XMLRPC::DateTime#to_date
-    Return a (({Date})) object of the date which (({self})) represents.
-    The (({Date})) object do ((*not*)) contain the time component (only date).
-
---- XMLRPC::DateTime#to_a
-    Returns all date/time components in an array.
-    Returns (({[year, month, day, hour, min, sec]})).

-= XMLRPC::BasicServer
-== Description
-Is the base class for all XML-RPC server-types (CGI, standalone).
-You can add handler and set a default handler.
-Do not use this server, as this is/should be an abstract class.
-
-=== How the method to call is found
-The arity (number of accepted arguments) of a handler (method or (({Proc})) object) is
-compared to the given arguments submitted by the client for a RPC ((-Remote Procedure Call-)).
-A handler is only called if it accepts the number of arguments, otherwise the search
-for another handler will go on. When at the end no handler was found,
-the ((<default_handler|XMLRPC::BasicServer#set_default_handler>)) will be called.
-With this technique it is possible to do overloading by number of parameters, but
-only for (({Proc})) handler, because you cannot define two methods of the same name in
-the same class.
-
-
-== Class Methods
---- XMLRPC::BasicServer.new( class_delim="." )
-    Creates a new (({XMLRPC::BasicServer})) instance, which should not be
-    done, because (({XMLRPC::BasicServer})) is an abstract class. This
-    method should be called from a subclass indirectly by a (({super})) call
-    in the method (({initialize})). The paramter ((|class_delim|)) is used
-    in ((<add_handler|XMLRPC::BasicServer#add_handler>)) when an object is
-    added as handler, to delimit the object-prefix and the method-name.
-
-== Instance Methods
---- XMLRPC::BasicServer#add_handler( name, signature=nil, help=nil ) { aBlock }
-    Adds ((|aBlock|)) to the list of handlers, with ((|name|)) as the name of the method.
-    Parameters ((|signature|)) and ((|help|)) are used by the Introspection method if specified,
-    where ((|signature|)) is either an Array containing strings each representing a type of it's
-    signature (the first is the return value) or an Array of Arrays if the method has multiple
-    signatures. Value type-names are "int, boolean, double, string, dateTime.iso8601, base64, array, struct".
-
-    Parameter ((|help|)) is a String with informations about how to call this method etc.
-
-    A handler method or code-block can return the types listed at
-    ((<XMLRPC::Client#call|URL:client.html#index:0>)).
-    When a method fails, it can tell it the client by throwing an
-    (({XMLRPC::FaultException})) like in this example:
-        s.add_handler("michael.div") do |a,b|
-          if b == 0
-            raise XMLRPC::FaultException.new(1, "division by zero")
-          else
-            a / b
-          end
-        end
-    The client gets in the case of (({b==0})) an object back of type
-    (({XMLRPC::FaultException})) that has a ((|faultCode|)) and ((|faultString|))
-    field.
-
---- XMLRPC::BasicServer#add_handler( prefix, obj )
-    This is the second form of ((<add_handler|XMLRPC::BasicServer#add_handler>)).
-    To add an object write:
-        server.add_handler("michael", MyHandlerClass.new)
-    All public methods of (({MyHandlerClass})) are accessible to
-    the XML-RPC clients by (('michael."name of method"')). This is
-    where the ((|class_delim|)) in ((<new|XMLRPC::BasicServer.new>))
-    has it's role, a XML-RPC method-name is defined by
-    ((|prefix|)) + ((|class_delim|)) + (('"name of method"')).
-
---- XMLRPC::BasicServer#add_handler( interface, obj )
-    This is the third form of ((<add_handler|XMLRPC::BasicServer#add_handler>)).
-
-    Use (({XMLRPC::interface})) to generate an ServiceInterface object, which
-    represents an interface (with signature and help text) for a handler class.
-
-    Parameter ((|interface|)) must be of type (({XMLRPC::ServiceInterface})).
-    Adds all methods of ((|obj|)) which are defined in ((|interface|)) to the
-    server.
-
-    This is the recommended way of adding services to a server!
-
-
---- XMLRPC::BasicServer#get_default_handler
-    Returns the default-handler, which is called when no handler for
-    a method-name is found.
-    It is a (({Proc})) object or (({nil})).
-
---- XMLRPC::BasicServer#set_default_handler ( &handler )
-    Sets ((|handler|)) as the default-handler, which is called when
-    no handler for a method-name is found. ((|handler|)) is a code-block.
-    The default-handler is called with the (XML-RPC) method-name as first argument, and
-    the other arguments are the parameters given by the client-call.
-
-    If no block is specified the default of (({XMLRPC::BasicServer})) is used, which raises a
-    XMLRPC::FaultException saying "method missing".
-
-
---- XMLRPC::BasicServer#set_writer( writer )
-    Sets the XML writer to use for generating XML output.
-    Should be an instance of a class from module (({XMLRPC::XMLWriter})).
-    If this method is not called, then (({XMLRPC::Config::DEFAULT_WRITER})) is used.
-
---- XMLRPC::BasicServer#set_parser( parser )
-    Sets the XML parser to use for parsing XML documents.
-    Should be an instance of a class from module (({XMLRPC::XMLParser})).
-    If this method is not called, then (({XMLRPC::Config::DEFAULT_PARSER})) is used.
-
---- XMLRPC::BasicServer#add_introspection
-    Adds the introspection handlers "system.listMethods", "system.methodSignature" and "system.methodHelp",
-    where only the first one works.
-
---- XMLRPC::BasicServer#add_multicall
-    Adds the multi-call handler "system.multicall".
-
---- XMLRPC::BasicServer#get_service_hook
-    Returns the service-hook, which is called on each service request (RPC) unless it's (({nil})).
-
---- XMLRPC::BasicServer#set_service_hook ( &handler )
-    A service-hook is called for each service request (RPC).
-    You can use a service-hook for example to wrap existing methods and catch exceptions of them or
-    convert values to values recognized by XMLRPC. You can disable it by passing (({nil})) as parameter
-    ((|handler|)) .
-
-    The service-hook is called with a (({Proc})) object and with the parameters for this (({Proc})).
-    An example:
-
-       server.set_service_hook {|obj, *args|
-         begin
-           ret = obj.call(*args)  # call the original service-method
-           # could convert the return value
-         rescue
-           # rescue exceptions
-         end
-       }

---- XMLRPC::CGIServer.new( *a )
-    Creates a new (({XMLRPC::CGIServer})) instance. All parameters given
-    are by-passed to ((<XMLRPC::BasicServer.new>)). You can only create
-    ((*one*)) (({XMLRPC::CGIServer})) instance, because more than one makes

-
-== Instance Methods
---- XMLRPC::CGIServer#serve
-    Call this after you have added all you handlers to the server.
-    This method processes a XML-RPC methodCall and sends the answer
-    back to the client.
-    Make sure that you don't write to standard-output in a handler, or in
-    any other part of your program, this would case a CGI-based server to fail!
