+	* ext/tk/tkutil/tkutil.c: improve handling callback-subst-keys. 
+	  Now, support longnam-keys (e.g. '%CTT' on tkdnd-2.0; however, still
+	  not support tkdnd-2.0 on tkextlib), and symbols of parameters (e.g. 
+	  :widget=>'%W', :keycode=>'%k', '%x'=>:x, '%X'=>:root_x, and so on; 
+	  those are attributes of event object). It means that Ruby/Tk accepts
+	  not only "widget.bind(ev, '%W', '%k', ...){|w, k, ...| ... }", but 
+	  also "widget.bind(ev, :widget, :keycode, ...){|w, k, ...| ... }". 
+	  It is potentially incompatible, when user passes symbols to the
+	  arguments of the callback block (the block receives the symbols as
+	  strings). I think that is very rare case (probably, used by Ruby/Tk
+	  experts only). When causes such trouble, please give strings instead
+	  of such symbol parameters (e.g. call Symbol#to_s method).

+	  Ruby/Tk scripts (use standard widgets) to force to use Ttk widgets.
+	  Ttk widgets don't have some options of standard widgets which are 
+	  control the view of widgets. When set ignore-mode true, configure 
+	  method tries to ignoure such unknown options with no exception. 
+	  Of course, it may raise other troubles on the GUI design. 
+	  So, those are a little danger methods. 
+
+	* ext/tk/lib/tk/itemconfig.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__

+	  purpose as TkConfigMethod's ones.

+	  wrapping old Ruby/Tk scripts (which use standard widgets) to use

+	  for 'fixed' option. But metrics method returns numeric value 
+	  (0 or 1) for 'fixed' option, because of backward compatibility. 
+
+	* ext/tk/lib/tk/timer.rb: somtimes fail to set callback procedure.
+
+	* ext/tk/lib/tk.rb: add Tk.sleep and Tk.wakeup method. Tk.sleep

+	  - Introduce versioning in Digest::Base API, and prefix C
+	    constants with RUBY_ and C type names with rb_ to avoid name
+	    clash in writing extensions.
+	  - Introduce Digest::Class and Digest::Instance for ease of
+	    implementing subclasses and add-ons.
+	  - Digest::Instance module requires and assumes that any instance
+	    be resettable and clonable.  An instance method #new() is
+	    added so digest instances work just like digest classes.
+	  - The constructor does no longer take an initial string to feed;
+	    digest() and hexdigest() now do, instead.  This allows digest
+	    classes to take their own hashing parameters.
+	  - Make some changes to digest() and hexdigest() class methods,
+	    which now take extra arguments, which are passed through to
+	    the constructor in an internal call.
+	  - Add #digest_length/size/length() and #block_length(),
+	  - Add the Digest::SHA2 class to wrap up SHA2 variants: SHA256,
+	    SHA384 and SHA512, hoping this module would make a decent
+	    example of a digest subclass written in Ruby.
+	  - Rip BubbleBabble support out of the base class and have a
+	    separate module named digest/bubblebabble.
+	  - Remove RD documents in favor of newly written and embedded
+	    RDoc documentation.

+	  * improved document/literal service support.
+	    style(rpc,document)/use(encoding, literal) combination are all
+	    supported.  for the detail about combination, see
+	    test/soap/test_style.rb.
+
+	  * let WSDLEncodedRegistry#soap2obj map SOAP/OM to Ruby according to
+	    WSDL as well as obj2soap.  closes #70.
+
+	  * let SOAP::Mapping::Object handle XML attribute for doc/lit service.
+	    you can set/get XML attribute via accessor methods which as a name
+	    'xmlattr_' prefixed (<foo name="bar"/> -> Foo#xmlattr_name).
+
+	  === client side ===
+
+	  * WSDLDriver capitalized name operation bug fixed.  from
+	    1.5.3-ruby1.8.2, operation which has capitalized name (such as
+	    KeywordSearchRequest in AWS) is defined as a method having
+	    uncapitalized name. (converted with GenSupport.safemethodname
+	    to handle operation name 'foo-bar').  it introduced serious
+	    incompatibility; in the past, it was defined as a capitalized.
+	    define capitalized method as well under that circumstance.
+
+	  * added new factory interface 'WSDLDriverFactory#create_rpc_driver'
+	    to create RPC::Driver, not WSDLDriver (RPC::Driver and WSDLDriver
+	    are merged).  'WSDLDriverFactory#create_driver' still creates
+	    WSDLDriver for compatibility but it warns that the method is
+	    deprecated.  please use create_rpc_driver instead of create_driver.
+
+	  * allow to use an URI object as an endpoint_url even with net/http,
+	    not http-access2.
+
+	  === server side ===
+
+	  * added mod_ruby support to SOAP::CGIStub.  rename a CGI script
+	    server.cgi to server.rb and let mod_ruby's RubyHandler handles the
+	    script.  CGIStub detects if it's running under mod_ruby environment
+	    or not.
+
+	  * added fcgi support to SOAP::CGIStub.  see the sample at
+	    sample/soap/calc/server.fcgi.  (almost same as server.cgi but has
+	    fcgi handler at the bottom.)
+
+	  * allow to return a SOAPFault object to respond customized SOAP fault.
+
+	  * added the interface 'generate_explicit_type' for server side
+	    (CGIStub, HTTPServer).  call 'self.generate_explicit_type = true'
+	    if you want to return simplified XML even if it's rpc/encoded
+	    service.
+
+	  == WSDL ==
+
+	  === WSDL definition ===
+
+	  * improved XML Schema support such as extension, restriction,
+	    simpleType, complexType + simpleContent, ref, length, import,
+	    include.
+
+	  * reduced "unknown element/attribute" warnings (warn only 1 time for
+	    each QName).
+
+	  * importing XSD file at schemaLocation with xsd:import.
+
+	  === code generation from WSDL ===
+
+	  * generator crashed when there's '-' in defined element/attribute
+	    name.
+
+	  * added ApacheMap WSDL definition.
+
+	* sample/{soap,wsdl}: removed.

+
+	* lib/logger.rb: leading 0 padding of timestamp usec part.
+
+	* lib/csv.rb (CSV.parse): [CAUTION] behavior changed.  in the past,
+	  CSV.parse accepts a filename to be read-opened (it was just a
+	  shortcut of CSV.open(filename, 'r')).  now CSV.parse accepts a
+	  string or a stream to be parsed e.g.
+	  CSV.parse("1,2\n3,r") #=> [['1', '2'], ['3', '4']]
+
+	* lib/csv.rb: CSV::Row and CSV::Cell are deprecated.  these classes
+	  are removed in the future.  in the new csv.rb, row is represented
+	  as just an Array.  since CSV::Row was a subclass of Array, it won't
+	  hurt almost all programs except one which depended CSV::Row#match.
+	  and a cell is represented as just a String or nil(NULL).  this
+	  change will cause widespread destruction.
+
+	      CSV.open("foo.csv", "r") do |row|
+		row.each do |cell|
+		  if cell.is_null       # using Cell#is_null
+		    p "(NULL)"
+		  else
+		    p cell.data         # using Cell#data
+		  end
+		end
+	      end
+
+	    must be just;
+
+	      CSV.open("foo.csv", "r") do |row|
+		row.each do |cell|
+		  if cell.nil?
+		    p "(NULL)"
+		  else
+		    p cell
+		  end
+		end
+	      end
+
+	* lib/csv.rb: [CAUTION] record separator(CR, LF, CR+LF) behavior
+	  change.  CSV.open, CSV.parse, and CSV,generate now do not force
+	  opened file binmode.  formerly it set binmode explicitly.
+
+	  with CSV.open, binmode of opened file depends the given mode
+	  parameter "r", "w", "rb", and "wb".  CSV.parse and CSV.generate open
+	  file with "r" and "w".
+
+	  setting mode properly is user's responsibility now.
+
+	* lib/csv.rb: accepts String as a fs (field separator/column separator)
+	  and rs (record separator/row separator)
+
+	* lib/csv.rb (CSV.read, CSV.readlines): added.  works as IO.read and
+	  IO.readlines in CSV format.
+
+	* lib/csv.rb: added CSV.foreach(path, rs = nil, &block).  CSV.foreach
+	  now does not handle "| cmd" as a path different from IO.foreach.

+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+* REXML
+
+  * REXML::Document.entity_expansion_limit=
+
+    New method to set the entity expansion limit. By default the limit is
+    set to 10000.  See the following URL for details.
+
+    http://www.ruby-lang.org/en/news/2008/08/23/dos-vulnerability-in-rexml/
+
+== Changes since the 1.8.6 release
+
+=== Configuration changes
+
+* vendor_ruby directory
+
+  A new library directory named `vendor_ruby' is introduced in
+  addition to `site_ruby'.  The idea is to separate libraries
+  installed by the package system (`vendor') from manually (`site')
+  installed libraries preventing the former from getting overwritten
+  by the latter, while preserving the user option to override vendor
+  libraries with site libraries. (`site_ruby' takes precedence over
+  `vendor_ruby')
+
+  If you are a package maintainer, make each library package configure
+  the library passing the `--vendor' option to `extconf.rb' so that
+  the library files will get installed under `vendor_ruby'.
+
+  You can change the directory locations using configure options such
+  as `--with-sitedir=DIR' and `--with-vendordir=DIR'.
+

+=== Interpreter Implementation
+
+* passing a block to a Proc [experimental]
+
+  This implementation in current shape is known to be buggy/broken,
+  especially with nested block invocation.  Take this as an
+  experimental feature.
+
+* stack trace
+
+  On non-SystemStackError exception, full stack trace is shown.
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* String#slice! had some unintentional bugs and they have been fixed
+  because either they disagreed with documentation or their respective
+  behavior of #slice.  Unfortunately, this causes some
+  incompatibilities in the following (somewhat rare) cases.
+
+  * #slice! no longer expands the array when an out-of-boundary value
+    is given.
+
+      # Ruby 1.8.6
+      a = [1,2]
+      a.slice!(4,0)   #=> nil
+      a               #=> [1,2,nil,nil]
+
+      # Ruby 1.8.7
+      a = [1,2]
+      a.slice!(4,0)   #=> nil
+      a               #=> [1,2]
+
+  * #slice! no longer raises an exception but returns nil when a
+    negative length or out-of-boundary negative position is given.
+
+      # Ruby 1.8.6
+      a = [1,2]
+      a.slice!(1,-1)  #=> (raises IndexError)
+      a.slice!(-5,1)  #=> (raises IndexError)
+
+      # Ruby 1.8.7
+      a = [1,2]
+      a.slice!(1,-1)  #=> nil
+      a.slice!(-5,1)  #=> nil
+
+* String#to_i, String#hex and String#oct no longer accept a sequence
+  of underscores (`__') as part of a number.
+
+    # Ruby 1.8.6
+    '1__0'.to_i     #=> 10
+    '1__0'.to_i(2)  #=> 2  # 0b10
+    '1__0'.oct      #=> 8  # 010
+    '1__0'.hex      #=> 16 # 0x10
+
+    # Ruby 1.8.7
+    '1__0'.to_i     #=> 1
+    '1__0'.to_i(2)  #=> 1
+    '1__0'.oct      #=> 1
+    '1__0'.hex      #=> 1
+
+  The old behavior was inconsistent with Ruby syntax and considered as
+  a bug.
+
+* date
+
+  * Date.parse
+
+    '##.##.##' (where each '#' is a digit) is now taken as 'YY.MM.DD'
+    instead of 'MM.DD.YY'.  While the change may confuse you, you can
+    always use Date.strptime() when you know what you are dealing
+    with.
+
+* stringio
+
+  * StringIO#each_byte
+
+    The return value changed from nil to self.  This is what the
+    document says and the same as each_line() does.
+
+* tempfile
+
+  * The file name format has changed.  No dots are included by default
+    in temporary file names any more.  See above for how to specify a
+    suffix.
+
+* uri
+
+  * See above for details.
+
+== Changes since the 1.8.5 release
+
+=== New platforms/build tools support
+
+* IA64 HP-UX
+
+* Visual C++ 8 SP1
+
+* autoconf 2.6x
+
+=== Global constants
+
+* RUBY_PATCHLEVEL
+
+  New constant since 1.8.5-p1.
+
+=== Library updates (outstanding ones only)
+
+* builtin classes
+
+  * New method: Kernel#instance_variable_defined?
+
+  * New method: Module#class_variable_defined?
+
+  * New feature: Dir::glob() can now take an array of glob patterns.
+
+* date
+
+  * Updated based on date2 4.0.3.
+
+* digest
+
+  * New internal APIs for C and Ruby.
+
+  * Support for autoloading.
+
+      require 'digest'
+
+      # autoloads digest/md5
+      md = Digest::MD5.digest("string")
+
+  * New digest class methods: file
+
+  * New digest instance methods: clone, reset, new, inspect,
+    digest_length (alias size or length), block_length()
+
+  * New library: digest/bubblebabble
+
+  * New function: Digest(name)
+
+* fileutils
+
+  * New option for FileUtils.cp_r(): :remove_destination
+
+* nkf
+
+  * Updated based on nkf as of 2007-01-28.
+
+* thread
+
+  * Replaced with much faster mutex implementation in C.  The former
+    implementation, which is slow but considered to be stable, is
+    available with a configure option `--disable-fastthread'.
+
+* tk
+
+  * Updated Tile extension support based on Tile 0.7.8.
+
+  * Support --without-X11 configure option for non-X11 versions of
+    Tcl/Tk (e.g. Tcl/Tk Aqua).
+
+  * New sample script: irbtkw.rbw -- IRB on Ruby/Tk. It has no trouble
+    about STDIN blocking on Windows.
+
+* webrick
+
+  * New method: WEBrick::Cookie.parse_set_cookies()
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* builtin classes
+
+  * String#intern now raises SecurityError when $SAFE level is greater
+    than zero.
+
+* date
+
+  * Time#to_date and Time#to_datetime are added as private methods.
+    They cause name conflict error in ActiveSupport 1.4.1 and prior,
+    which comes with Rails 1.2.2 and prior.  Updating ActiveSupport
+    and/or Rails to the latest versions fixes the problem.
+
+* digest
+
+  * The constructor does no longer take an initial string to feed.
+    The following examples show how to migrate:
+
+      # Before
+      md = Digest::MD5.new("string")
+      # After (works with any version)
+      md = Digest::MD5.new.update("string")
+        
+      # Before
+      hd = Digest::MD5.new("string").hexdigest
+      # After (works with any version)
+      hd = Digest::MD5.hexdigest("string")
+
+* fileutils
+
+  * A minor implementation change breaks Rake <=0.7.1.
+    Updating Rake to 0.7.2 or higher fixes the problem.
+
+* tk
+
+  * Tk::X_Scrollable (Y_Scrollable) is renamed to Tk::XScrollable
+    (YScrollable). Tk::X_Scrollable (Y_Scrollable) is still available,
+    but it is an alias name.

+# == Installing Documentation
+#
+# 'ri' uses a database of documentation built by the RDoc utility.
+# 
+# So, how do you install this documentation on your system?
+# It depends on how you installed Ruby.
+#
+# <em>If you installed Ruby from source files</em> (that is, if it some point
+# you typed 'make' during the process :), you can install the RDoc
+# documentation yourself. Just go back to the place where you have 
+# your Ruby source and type
+#
+#    make install-doc
+#
+# You'll probably need to do this as a superuser, as the documentation
+# is installed in the Ruby target tree (normally somewhere under 
+# <tt>/usr/local</tt>.
+#
+# <em>If you installed Ruby from a binary distribution</em> (perhaps
+# using a one-click installer, or using some other packaging system),
+# then the team that produced the package probably forgot to package
+# the documentation as well. Contact them, and see if they can add
+# it to the next release.

+ *
+ *  However, consider the case where comparing the keys is a non-trivial
+ *  operation. The following code sorts some files on modification time
+ *  using the basic <code>sort</code> method.
+ *
+ *     files = Dir["*"]
+ *     sorted = files.sort {|a,b| File.new(a).mtime <=> File.new(b).mtime}

+ *
+ *  This sort is inefficient: it generates two new <code>File</code>
+ *  objects during every comparison. A slightly better technique is to
+ *  use the <code>Kernel#test</code> method to generate the modification
+ *  times directly.
+ *
+ *     files = Dir["*"]
+ *     sorted = files.sort { |a,b|
+ *       test(?M, a) <=> test(?M, b)
+ *     }
+ *     sorted   #=> ["mon", "tues", "wed", "thurs"]
+ *
+ *  This still generates many unnecessary <code>Time</code> objects. A
+ *  more efficient technique is to cache the sort keys (modification
+ *  times in this case) before the sort. Perl users often call this
+ *  approach a Schwartzian Transform, after Randal Schwartz. We
+ *  construct a temporary array, where each element is an array
+ *  containing our sort key along with the filename. We sort this array,
+ *  and then extract the filename from the result.
+ *
+ *     sorted = Dir["*"].collect { |f|
+ *        [test(?M, f), f]
+ *     }.sort.collect { |f| f[1] }
+ *     sorted   #=> ["mon", "tues", "wed", "thurs"]
+ *
+ *  This is exactly what <code>sort_by</code> does internally.

+ *  will start <code>Errno::</code>.
+ *     
+ *  The names of the <code>Errno::</code> classes depend on
+ *  the environment in which Ruby runs. On a typical Unix or Windows
+ *  platform, there are <code>Errno</code> classes such as
+ *  <code>Errno::EACCES</code>, <code>Errno::EAGAIN</code>,
+ *  <code>Errno::EINTR</code>, and so on.
+ *     
+ *  The integer operating system error number corresponding to a
+ *  particular error is available as the class constant
+ *  <code>Errno::</code><em>error</em><code>::Errno</code>.
+ *     
+ *     Errno::EACCES::Errno   #=> 13
+ *     Errno::EAGAIN::Errno   #=> 11

+ * Document-class: UnboundMethod
+ *
+ *  Ruby supports two forms of objectified methods. Class
+ *  <code>Method</code> is used to represent methods that are associated
+ *  with a particular object: these method objects are bound to that
+ *  object. Bound method objects for an object can be created using
+ *  <code>Object#method</code>.
+ *     
+ *  Ruby also supports unbound methods; methods objects that are not
+ *  associated with a particular object. These can be created either by
+ *  calling <code>Module#instance_method</code> or by calling
+ *  <code>unbind</code> on a bound method object. The result of both of
+ *  these is an <code>UnboundMethod</code> object.
+ *     
+ *  Unbound methods can only be called after they are bound to an
+ *  object. That object must be be a kind_of? the method's original
+ *  class.
+ *     
+ *     class Square
+ *       def area
+ *         @side * @side
+ *       end
+ *       def initialize(side)
+ *         @side = side
+ *       end
+ *     end
+ *     
+ *     area_un = Square.instance_method(:area)
+ *     
+ *     s = Square.new(12)
+ *     area = area_un.bind(s)
+ *     area.call   #=> 144
+ *     
+ *  Unbound methods are a reference to the method at the time it was
+ *  objectified: subsequent changes to the underlying class will not
+ *  affect the unbound method.
+ *     
+ *     class Test
+ *       def test
+ *         :original

+/* BigDecimal provides arbitrary-precision floating point decimal arithmetic.
+ *
+ * Copyright (C) 2002 by Shigeo Kobayashi <shigeo@tinyforest.gr.jp>.
+ * You may distribute under the terms of either the GNU General Public
+ * License or the Artistic License, as specified in the README file
+ * of the BigDecimal distribution.
+ *
+ * Documented by mathew <meta@pobox.com>.
+ *
+ * = Introduction
+ *
+ * Ruby provides built-in support for arbitrary precision integer arithmetic.
+ * For example:
+ *
+ * 42**13   ->   1265437718438866624512
+ *
+ * BigDecimal provides similar support for very large or very accurate floating
+ * point numbers.
+ *
+ * Decimal arithmetic is also useful for general calculation, because it
+ * provides the correct answers people expect--whereas normal binary floating
+ * point arithmetic often introduces subtle errors because of the conversion
+ * between base 10 and base 2. For example, try:
+ *
+ *   sum = 0
+ *   for i in (1..10000)
+ *     sum = sum + 0.0001
+ *   end
+ *   print sum
+ *
+ * and contrast with the output from:
+ *
+ *   require 'bigdecimal'
+ *
+ *   sum = BigDecimal.new("0")
+ *   for i in (1..10000)
+ *     sum = sum + BigDecimal.new("0.0001")
+ *   end
+ *   print sum
+ *
+ * Similarly:
+ *
+ * (BigDecimal.new("1.2") - BigDecimal("1.0")) == BigDecimal("0.2") -> true
+ *
+ * (1.2 - 1.0) == 0.2 -> false
+ *
+ * = Special features of accurate decimal arithmetic
+ *
+ * Because BigDecimal is more accurate than normal binary floating point
+ * arithmetic, it requires some special values.
+ *
+ * == Infinity
+ *
+ * BigDecimal sometimes needs to return infinity, for example if you divide
+ * a value by zero.
+ *
+ * BigDecimal.new("1.0") / BigDecimal.new("0.0")  -> infinity
+ *
+ * BigDecimal.new("-1.0") / BigDecimal.new("0.0")  -> -infinity
+ *
+ * You can represent infinite numbers to BigDecimal using the strings
+ * 'Infinity', '+Infinity' and '-Infinity' (case-sensitive)
+ *
+ * == Not a Number
+ *
+ * When a computation results in an undefined value, the special value NaN
+ * (for 'not a number') is returned.
+ *
+ * Example:
+ *
+ * BigDecimal.new("0.0") / BigDecimal.new("0.0") -> NaN
+ *
+ * You can also create undefined values.  NaN is never considered to be the
+ * same as any other value, even NaN itself:
+ *
+ * n = BigDecimal.new('NaN')
+ *
+ * n == 0.0 -> nil
+ *
+ * n == n -> nil
+ *
+ * == Positive and negative zero
+ *
+ * If a computation results in a value which is too small to be represented as
+ * a BigDecimal within the currently specified limits of precision, zero must
+ * be returned.
+ *
+ * If the value which is too small to be represented is negative, a BigDecimal
+ * value of negative zero is returned. If the value is positive, a value of
+ * positive zero is returned.
+ *
+ * BigDecimal.new("1.0") / BigDecimal.new("-Infinity") -> -0.0
+ *
+ * BigDecimal.new("1.0") / BigDecimal.new("Infinity") -> 0.0
+ *
+ * (See BigDecimal.mode for how to specify limits of precision.)
+ *
+ * Note that -0.0 and 0.0 are considered to be the same for the purposes of
+ * comparison.
+ *
+ * Note also that in mathematics, there is no particular concept of negative 
+ * or positive zero; true mathematical zero has no sign.

 <H3>Disadvantage of decimal representation</H3>
-Advantages stated so far can also be disadvantages if the input from outside is
- represented in binary.
-Translation error from decimal to binary or vice versa is inevitable.
-So,translation from Float(binary) to BigDecimal(decimal) is not alway done exactly.
+Because most computers have no internal decimal representaion.
+Once you use BigDecimal,you need to keep using it without
+considering computation cost if exact computation is required.

-** MD5(Class)
-
-A class to implement the MD5 Message-Digest Algorithm by RSA Data
-Security, Inc., described in RFC1321.
-
-Superclass: Digest::Base
-
-require 'digest/md5'
-
-** SHA1(Class)
-
-A class to implement the SHA-1 Secure Hash Algorithm by NIST (the US'
-National Institute of Standards and Technology), described in FIPS PUB
-180-1.
-
-Superclass: Digest::Base
-
-require 'digest/sha1'
-
-** SHA256(Class)
-** SHA384(Class)
-** SHA512(Class)
-
-Classes to implement the SHA-256/384/512 Secure Hash Algorithm(s) by
-NIST (the US' National Institute of Standards and Technology),
-described in FIPS PUB 180-2.
-
-Superclass: Digest::Base
-
-require 'digest/sha2'
-
-** RMD160(Class)
-
-A class to implement the RIPEMD-160 cryptographic hash function,
-designed by Hans Dobbertin, Antoon Bosselaers, and Bart Preneel.
-
-Superclass: Digest::Base
-
-require 'digest/rmd160'
-
-
-Those above classes provide a common interface as shown below.
-
-
-Class Methods:
-
-   new([str])
-
-	Creates a new digest object.  If a string argument is given,
-	it is added to the object. (see update.)
-
-   digest(str)
-
-	Immediately calculates and return the hash of the given
-	strings as a string.  Equivalent to new(str).digest.
-
-   hexdigest(str)
-
-	Immediately calculates and return the hash of the given
-	strings as a string of hexadecimal digits.  Equivalent to
-	new(str).hexdigest.
-
-Methods:
-
-   clone
-
-	Creates a copy of the digest object.
-
-   digest
-
-	Returns the hash of the added strings as a string of 16 bytes
-	for MD5, 20 bytes for SHA1 and RMD160, 32 bytes for SHA256, 48
-	bytes for SHA384, and 64 bytes for SHA512.
-
-   hexdigest
-   to_s
-
-	Returns the hash of the added strings as a string of 32
-	hexadecimal digits for MD5, 40 hexadecimal digits for SHA1 and
-	RMD160, 64 hexadecimal digits for SHA256, 96 hexadecimal
-	digits for SHA384, and 128 hexadecimal digits for SHA512.
-	This method is equal to:
-
-	def hexdigest
-	  digest.unpack("H*")[0]
-	end
-
-   update(str)
-   << str
-
-	Appends the string str to the digest object.  Repeated calls
-	are equivalent to a single call with the concatenation of all
-	the arguments, i.e. m.update(a); m.update(b) is equivalent to
-	m.update(a + b) and m << a << b is equivalent to m << a + b.
-
-   == md
-
-	Checks if the object is equal to the given digest object.
-
-   == str
-
-	Regards the value as either a digest value or a hexdigest
-	value (depending on the length) and checks if the object is
-	equal to the given string.

-** Enumerable::Enumerator(Class)
-
-A class which provides a method `each' to be used as an Enumerable
-object.
-
-Superclass: Object
-
-Mix-ins: Enumerable
-
-require 'enumerator'
-
-Class Methods:
-
-    new(obj, method = :each, *args)
-
-	Creates a new Enumerable::Enumerator object, which is to be
-	used as an Enumerable object using the given object's given
-	method with the given arguments.
-
-	e.g.:
-	    str = "xyz"
-
-	    enum = Enumerable::Enumerator.new(str, :each_byte)
-	    a = enum.map {|b| '%02x' % b } #=> ["78", "79", "7a"]
-
-Methods:
-
-    each {...}
-
-	Iterates the given block using the object and the method
-	specified in the first place.
-
-
-Requiring this module also adds some methods to the Object class:
-
-    to_enum(method = :each, *args)
-    enum_for(method = :each, *args)
-
-	Returns Enumerable::Enumerator.new(self, method, *args).
-
-	e.g.:
-	    str = "xyz"
-
-	    enum = str.enum_for(:each_byte)
-	    a = enum.map {|b| '%02x' % b } #=> ["78", "79", "7a"]
-
-	    # protects an array from being modified
-	    a = [1, 2, 3]
-	    some_method(a.to_enum)
-
-And the Enumerable module.
-
-    each_slice(n) {...}
-
-	Iterates the given block for each slice of <n> elements.
-
-	e.g.:
-	    (1..10).each_slice(3) {|a| p a}
-	    # outputs below
-	    [1, 2, 3]
-	    [4, 5, 6]
-	    [7, 8, 9]
-	    [10]
-
-    enum_slice(n)
-
-	Returns Enumerable::Enumerator.new(self, :each_slice, n).
-
-    each_cons(n) {...}
-
-	Iterates the given block for each array of consecutive <n>
-	elements.
-
-	e.g.:
-	    (1..10).each_cons(3) {|a| p a}
-	    # outputs below
-	    [1, 2, 3]
-	    [2, 3, 4]
-	    [3, 4, 5]
-	    [4, 5, 6]
-	    [5, 6, 7]
-	    [6, 7, 8]
-	    [7, 8, 9]
-	    [8, 9, 10]
-
-    enum_cons(n)
-
-	Returns Enumerable::Enumerator.new(self, :each_cons, n).
-
-    enum_with_index
-
-	Returns Enumerable::Enumerator.new(self, :each_with_index).

+ *
+ * Copyright (C) 1997-2001 Yukihiro Matsumoto
+ *
+ * Documented by mathew <meta@pobox.com>
+ *
+ * = Usage
+ * 
+ * To perform a fcntl(2) operation, use IO::fcntl in the core classes.
+ *
+ * To perform an open(2) operation, use IO::sysopen.
+ *
+ * The set of operations and constants available depends upon specific OS
+ * platform. Some values listed below may not be supported on your system.
+ *
+ * The constants supported by Ruby for use with IO::fcntl are:
+ *
+ * - F_DUPFD - duplicate a close-on-exec file handle to a non-close-on-exec
+ *   file handle.
+ *
+ * - F_GETFD - read the close-on-exec flag of a file handle.
+ *
+ * - F_SETFD - set the close-on-exec flag of a file handle.
+ *
+ * - FD_CLOEXEC - the value of the close-on-exec flag.
+ *
+ * - F_GETFL - get file descriptor flags.
+ *
+ * - F_SETFL - set file descriptor flags.
+ *
+ * - O_APPEND, O_NONBLOCK, etc (see below) - file descriptor flag
+ *   values for the above.
+ *
+ * - F_GETLK - determine whether a given region of a file is locked.
+ *
+ * - F_SETLK - acquire a lock on a region of a file.
+ *
+ * - F_SETLKW - acquire a lock on a region of a file, waiting if necessary.
+ *
+ * - F_RDLCK, F_WRLCK, F_UNLCK - types of lock for the above.
+ *
+ * The constants supported by Ruby for use with IO::sysopen are:
+ *
+ * - O_APPEND - open file in append mode.
+ *
+ * - O_NOCTTY - open tty without it becoming controlling tty.
+ *
+ * - O_CREAT - create file if it doesn't exist.
+ *
+ * - O_EXCL - used with O_CREAT, fail if file exists.
+ *
+ * - O_TRUNC - truncate file on open.
+ *
+ * - O_NONBLOCK / O_NDELAY - open in non-blocking mode.
+ *
+ * - O_RDONLY - open read-only.
+ *
+ * - O_WRONLY - open write-only.
+ *
+ * - O_RDWR - open read-write.
+ *
+ * - O_ACCMODE - mask to extract read/write flags.
+ *
+ * Example:
+ * 
+ *   require 'fcntl'
+ *
+ *   fd = IO::sysopen('/tmp/tempfile', 
+ *        Fcntl::O_WRONLY | Fcntl::O_EXCL | Fcntl::O_CREAT)
+ *   f = IO.open(fd)
+ *   f.syswrite("TEMP DATA")
+ *   f.close

+ * Document-class: GDBM
+ *
+ * == Summary
+ *
+ * Ruby extension for GNU dbm (gdbm) -- a simple database engine for storing
+ * key-value pairs on disk.
+ *
+ * == Description
+ *
+ * GNU dbm is a library for simple databases. A database is a file that stores
+ * key-value pairs. Gdbm allows the user to store, retrieve, and delete data by
+ * key. It furthermore allows a non-sorted traversal of all key-value pairs.
+ * A gdbm database thus provides the same functionality as a hash. As
+ * with objects of the Hash class, elements can be accessed with <tt>[]</tt>.
+ * Furthermore, GDBM mixes in the Enumerable module, thus providing convenient
+ * methods such as #find, #collect, #map, etc.
+ *
+ * A process is allowed to open several different databases at the same time.
+ * A process can open a database as a "reader" or a "writer". Whereas a reader
+ * has only read-access to the database, a writer has read- and write-access.
+ * A database can be accessed either by any number of readers or by exactly one
+ * writer at the same time.
+ *
+ * == Examples
+ *
+ * 1. Opening/creating a database, and filling it with some entries:
+ *
+ *      require 'gdbm'
+ *      
+ *      gdbm = GDBM.new("fruitstore.db")
+ *      gdbm["ananas"]    = "3"
+ *      gdbm["banana"]    = "8"
+ *      gdbm["cranberry"] = "4909"
+ *      gdbm.close
+ *
+ * 2. Reading out a database:
+ *
+ *      require 'gdbm'
+ *      
+ *      gdbm = GDBM.new("fruitstore.db")
+ *      gdbm.each_pair do |key, value|
+ *        print "#{key}: #{value}\n"
+ *      end
+ *      gdbm.close
+ *
+ *    produces
+ *
+ *      banana: 8
+ *      ananas: 3
+ *      cranberry: 4909
+ *
+ * == Links

+ * == Summary

+ * Ruby extension for charset conversion.
+ * 
+ * == Abstract
+ *
+ * Iconv is a wrapper class for the UNIX 95 <tt>iconv()</tt> function family,
+ * which translates string between various encoding systems.
+ * 
+ * See Open Group's on-line documents for more details.

+ *  NKF - Ruby extension for Network Kanji Filter 
+ *
+ *  == Description
+ *
+ *  This is a Ruby Extension version of nkf (Netowrk Kanji Filter).
+ *  It converts the first argument and return converted result. Conversion
+ *  details are specified by flags as the first argument.
+ *
+ *  *Nkf* is a yet another kanji code converter among networks, hosts and terminals.
+ *  It converts input kanji code to designated kanji code
+ *  such as ISO-2022-JP, Shift_JIS, EUC-JP, UTF-8 or UTF-16.
+ *
+ *  One of the most unique faculty of *nkf* is the guess of the input kanji encodings.
+ *  It currently recognizes ISO-2022-JP, Shift_JIS, EUC-JP, UTF-8 and UTF-16.
+ *  So users needn't set the input kanji code explicitly.
+ *
+ *  By default, X0201 kana is converted into X0208 kana.
+ *  For X0201 kana, SO/SI, SSO and ESC-(-I methods are supported.
+ *  For automatic code detection, nkf assumes no X0201 kana in Shift_JIS.
+ *  To accept X0201 in Shift_JIS, use <b>-X</b>, <b>-x</b> or <b>-S</b>.
+ *
+ *  == Flags
+ *
+ *  === -b -u
+ *
+ *  Output is buffered (DEFAULT), Output is unbuffered.
+ *
+ *  === -j -s -e -w -w16
+ *
+ *  Output code is ISO-2022-JP (7bit JIS), Shift_JIS, EUC-JP,
+ *  UTF-8N, UTF-16BE.
+ *  Without this option and compile option, ISO-2022-JP is assumed.
+ *
+ *  === -J -S -E -W -W16
+ *
+ *  Input assumption is JIS 7 bit, Shift_JIS, EUC-JP,
+ *  UTF-8, UTF-16LE.
+ *
+ *  ==== -J
+ *
+ *  Assume  JIS input. It also accepts EUC-JP.
+ *  This is the default. This flag does not exclude Shift_JIS.
+ *
+ *  ==== -S
+ *
+ *  Assume Shift_JIS and X0201 kana input. It also accepts JIS.
+ *  EUC-JP is recognized as X0201 kana. Without <b>-x</b> flag,
+ *  X0201 kana (halfwidth kana) is converted into X0208.
+ *
+ *  ==== -E
+ *
+ *  Assume EUC-JP input. It also accepts JIS.
+ *  Same as -J.
+ *
+ *  === -t
+ *
+ *  No conversion.
+ *
+ *  === -i_
+ *
+ *  Output sequence to designate JIS-kanji. (DEFAULT B)
+ *
+ *  === -o_
+ *
+ *  Output sequence to designate ASCII. (DEFAULT B)
+ *
+ *  === -r
+ *
+ *  {de/en}crypt ROT13/47
+ *
+ *  === -h[123] --hiragana --katakana --katakana-hiragana
+ *
+ *  [-h1 --hiragana] Katakana to Hiragana conversion.
+ *
+ *  [-h2 --katakana] Hiragana to Katakana conversion.
+ *
+ *  [-h3 --katakana-hiragana] Katakana to Hiragana and Hiragana to Katakana conversion.
+ *
+ *  === -T
+ *
+ *  Text mode output (MS-DOS)
+ *
+ *  === -l
+ *
+ *  ISO8859-1 (Latin-1) support
+ *
+ *  === -f[<code>m</code> [- <code>n</code>]]
+ *
+ *  Folding on <code>m</code> length with <code>n</code> margin in a line.
+ *  Without this option, fold length is 60 and fold margin is 10.
+ *
+ *  === -F
+ *
+ *  New line preserving line folding.
+ *
+ *  === -Z[0-3]
+ *
+ *  Convert X0208 alphabet (Fullwidth Alphabets) to ASCII.
+ *
+ *  [-Z -Z0] Convert X0208 alphabet to ASCII.
+ *
+ *  [-Z1] Converts X0208 kankaku to single ASCII space.
+ *
+ *  [-Z2] Converts X0208 kankaku to double ASCII spaces.
+ *
+ *  [-Z3] Replacing Fullwidth >, <, ", & into '&gt;', '&lt;', '&quot;', '&amp;' as in HTML.
+ *
+ *  === -X -x
+ *
+ *  Assume X0201 kana in MS-Kanji.
+ *  With <b>-X</b> or without this option, X0201 is converted into X0208 Kana.
+ *  With <b>-x</b>, try to preserve X0208 kana and do not convert X0201 kana to X0208.
+ *  In JIS output, ESC-(-I is used. In EUC output, SSO is used.
+ *
+ *  === -B[0-2]
+ *
+ *  Assume broken JIS-Kanji input, which lost ESC.
+ *  Useful when your site is using old B-News Nihongo patch.
+ *
+ *  [-B1] allows any char after ESC-( or ESC-$.
+ *
+ *  [-B2] forces ASCII after NL.
+ *
+ *  === -I
+ *
+ *  Replacing non iso-2022-jp char into a geta character
+ *  (substitute character in Japanese).
+ *
+ *  === -d -c
+ *
+ *  Delete \r in line feed, Add \r in line feed.
+ *
+ *  === -m[BQN0]
+ *
+ *  MIME ISO-2022-JP/ISO8859-1 decode. (DEFAULT)
+ *  To see ISO8859-1 (Latin-1) -l is necessary.
+ *
+ *  [-mB] Decode MIME base64 encoded stream. Remove header or other part before
+ *  conversion. 
+ *
+ *  [-mQ] Decode MIME quoted stream. '_' in quoted stream is converted to space.
+ *
+ *  [-mN] Non-strict decoding.
+ *  It allows line break in the middle of the base64 encoding.
+ *
+ *  [-m0] No MIME decode.
+ *
+ *  === -M
+ *
+ *  MIME encode. Header style. All ASCII code and control characters are intact.
+ *  Kanji conversion is performed before encoding, so this cannot be used as a picture encoder.
+ *
+ *  [-MB] MIME encode Base64 stream.
+ *
+ *  [-MQ] Perfome quoted encoding.
+ *
+ *  === -l
+ *
+ *  Input and output code is ISO8859-1 (Latin-1) and ISO-2022-JP.
+ *  <b>-s</b>, <b>-e</b> and <b>-x</b> are not compatible with this option.
+ *
+ *  === -L[uwm]
+ *
+ *  new line mode
+ *  Without this option, nkf doesn't convert line breaks.

-== class Net::HTTP
-
-== Example
-
-Simple HTTP client is here:
-
-    require 'net/http'
-    host, port, path = "localhost", 80, "/"
-    if %r!http://(.*?)(?::(\d+))?(/.*)! =~ ARGV[0]
-      host   = $1
-      port   = $2.to_i if $2
-      path   = $3
-    end
-    h = Net::HTTP.new(host, port)
-    h.get2(path){ |resp| print resp.body }
-
-It can be replaced by follow one:
-
-    require 'net/https'
-    host, port, path = "localhost", 80, "/"
-    if %r!(https?)://(.*?)(?::(\d+))?(/.*)! =~ ARGV[0]
-      scheme = $1
-      host   = $2
-      port   = $3 ? $3.to_i : ((scheme == "http") ? 80 : 443)
-      path   = $4
-    end
-    h = Net::HTTP.new(host, port)
-    h.use_ssl = true if scheme == "https" # enable SSL/TLS
-    h.get2(path){ |resp| print resp.body }
-
-=== Instance Methods
-
-: use_ssl
-    returns ture if use SSL/TLS with HTTP.
-
-: use_ssl=((|true_or_false|))
-    sets use_ssl.
-
-: peer_cert
-    return the X.509 certificates the server presented.
-
-: key=((|key|))
-    Sets an OpenSSL::PKey::RSA or OpenSSL::PKey::DSA object.
-    (This method is appeared in Michal Rokos's OpenSSL extention.)
-
-: key_file=((|path|))
-    Sets a private key file to use in PEM format.
-
-: cert=((|cert|))
-    Sets an OpenSSL::X509::Certificate object as client certificate.
-    (This method is appeared in Michal Rokos's OpenSSL extention.)
-
-: cert_file=((|path|))
-    Sets pathname of a X.509 certification file in PEM format.
-
-: ca_file=((|path|))
-    Sets path of a CA certification file in PEM format.
-    The file can contrain several CA certificats.
-
-: ca_path=((|path|))
-    Sets path of a CA certification directory containing certifications
-    in PEM format.
-
-: verify_mode=((|mode|))
-    Sets the flags for server the certification verification at
-    begining of SSL/TLS session.
-    OpenSSL::SSL::VERIFY_NONE or OpenSSL::SSL::VERIFY_PEER is acceptable.
-
-: verify_callback=((|proc|))
-    Sets the verify callback for the server certification verification.
-
-: verify_depth=((|num|))
-    Sets the maximum depth for the certificate chain verification.
-
-: cert_store=((|store|))
-    Sets the X509::Store to verify peer certificate.

+ * Document-method: setsockopt
+ * call-seq: setsockopt(level, optname, optval)
+ *
+ * Sets a socket option. These are protocol and system specific, see your
+ * local sytem documentation for details.
+ *
+ * === Parameters
+ * * +level+ is an integer, usually one of the SOL_ constants such as
+ *   Socket::SOL_SOCKET, or a protocol level.
+ * * +optname+ is an integer, usually one of the SO_ constants, such
+ *   as Socket::SO_REUSEADDR.
+ * * +optval+ is the value of the option, it is passed to the underlying
+ *   setsockopt() as a pointer to a certain number of bytes. How this is
+ *   done depends on the type:
+ *   - Fixnum: value is assigned to an int, and a pointer to the int is
+ *     passed, with length of sizeof(int).
+ *   - true or false: 1 or 0 (respectively) is assigned to an int, and the
+ *     int is passed as for a Fixnum. Note that +false+ must be passed,
+ *     not +nil+.
+ *   - String: the string's data and length is passed to the socket.
+ *
+ * === Examples
+ *
+ * Some socket options are integers with boolean values, in this case
+ * #setsockopt could be called like this:
+ *   sock.setsockopt(Socket::SOL_SOCKET,Socket::SO_REUSEADDR, true)
+ *
+ * Some socket options are integers with numeric values, in this case
+ * #setsockopt could be called like this:
+ *   sock.setsockopt(Socket::IPPROTO_IP, Socket::IP_TTL, 255)
+ *
+ * Option values may be structs. Passing them can be complex as it involves
+ * examining your system headers to determine the correct definition. An
+ * example is an +ip_mreq+, which may be defined in your system headers as:
+ *   struct ip_mreq {
+ *     struct  in_addr imr_multiaddr;
+ *     struct  in_addr imr_interface;
+ *   };
+ * 
+ * In this case #setsockopt could be called like this:
+ *   optval =  IPAddr.new("224.0.0.251") + Socket::INADDR_ANY

+ * * Errno::ENOTSOCK - the +socket+ does not refer to a socket
+ * * Errno::EOPNOTSUPP - the specified flags are not supported for this socket type
+ * * Errno::ETIMEDOUT - the connection timed out during connection establishment
+ *   or due to a transmission timeout on an active connection
+ * 
+ * === Windows Exceptions
+ * On Windows systems the following system exceptions may be raised if 
+ * the call to _recvfrom_ fails:
+ * * Errno::ENETDOWN - the network is down
+ * * Errno::EFAULT - the internal buffer and from parameters on +socket+ are not
+ *   part of the user address space, or the internal fromlen parameter is
+ *   too small to accomodate the peer address
+ * * Errno::EINTR - the (blocking) call was cancelled by an internal call to
+ *   the WinSock function WSACancelBlockingCall
+ * * Errno::EINPROGRESS - a blocking Windows Sockets 1.1 call is in progress or 
+ *   the service provider is still processing a callback function
+ * * Errno::EINVAL - +socket+ has not been bound with a call to _bind_, or an
+ *   unknown flag was specified, or MSG_OOB was specified for a socket with
+ *   SO_OOBINLINE enabled, or (for byte stream-style sockets only) the internal
+ *   len parameter on +socket+ was zero or negative
+ * * Errno::EISCONN - +socket+ is already connected. The call to _recvfrom_ is
+ *   not permitted with a connected socket on a socket that is connetion 
+ *   oriented or connectionless.
+ * * Errno::ENETRESET - the connection has been broken due to the keep-alive 
+ *   activity detecting a failure while the operation was in progress.
+ * * Errno::EOPNOTSUPP - MSG_OOB was specified, but +socket+ is not stream-style
+ *   such as type SOCK_STREAM. OOB data is not supported in the communication
+ *   domain associated with +socket+, or +socket+ is unidirectional and 
+ *   supports only send operations
+ * * Errno::ESHUTDOWN - +socket+ has been shutdown. It is not possible to 
+ *   call _recvfrom_ on a socket after _shutdown_ has been invoked.
+ * * Errno::EWOULDBLOCK - +socket+ is marked as nonblocking and a  call to 
+ *   _recvfrom_ would block.
+ * * Errno::EMSGSIZE - the message was too large to fit into the specified buffer
+ *   and was truncated.
+ * * Errno::ETIMEDOUT - the connection has been dropped, because of a network
+ *   failure or because the system on the other end went down without
+ *   notice
+ * * Errno::ECONNRESET - the virtual circuit was reset by the remote side 
+ *   executing a hard or abortive close. The application should close the
+ *   socket; it is no longer usable. On a UDP-datagram socket this error
+ *   indicates a previous send operation resulted in an ICMP Port Unreachable

+/*
+ * Document-method: getaddrinfo
+ * call-seq: Socket.getaddrinfo(host, service, family=nil, socktype=nil, protocol=nil, flags=nil) => addrinfo
+ *
+ * Return address information for +host+ and +port+. The remaining arguments
+ * are hints that limit the address information returned.
+ *
+ * This method corresponds closely to the POSIX.1g getaddrinfo() definition.
+ *
+ * === Parameters
+ * - +host+ is a host name or an address string (dotted decimal for IPv4, or a hex string
+ *   for IPv6) for which to return information. A nil is also allowed, its meaning
+ *   depends on +flags+, see below.
+ * - +service+ is a service name ("http", "ssh", ...), or 
+ *   a port number (80, 22, ...), see Socket.getservbyname for more
+ *   information. A nil is also allowed, meaning zero.
+ * - +family+ limits the output to a specific address family, one of the
+ *   Socket::AF_* constants. Socket::AF_INET (IPv4) and Socket::AF_INET6 (IPv6)
+ *   are the most commonly used families. You will usually pass either nil or
+ *   Socket::AF_UNSPEC, allowing the IPv6 information to be returned first if
+ *   +host+ is reachable via IPv6, and IPv4 information otherwise.  The two
+ *   strings "AF_INET" or "AF_INET6" are also allowed, they are converted to
+ *   their respective Socket::AF_* constants.
+ * - +socktype+ limits the output to a specific type of socket, one of the
+ *   Socket::SOCK_* constants. Socket::SOCK_STREAM (for TCP) and
+ *   Socket::SOCK_DGRAM (for UDP) are the most commonly used socket types. If
+ *   nil, then information for all types of sockets supported by +service+ will
+ *   be returned. You will usually know what type of socket you intend to
+ *   create, and should pass that socket type in.
+ * - +protocol+ limits the output to a specific protocol numpber, one of the
+ *   Socket::IPPROTO_* constants. It is usually implied by the socket type
+ *   (Socket::SOCK_STREAM => Socket::IPPROTO_TCP, ...), if you pass other than
+ *   nil you already know what this is for.
+ * - +flags+ is one of the Socket::AI_* constants. They mean:
+ *   - Socket::AI_PASSIVE: when set, if +host+ is nil the 'any' address will be
+ *     returned, Socket::INADDR_ANY or 0 for IPv4, "0::0" or "::" for IPv6.  This
+ *     address is suitable for use by servers that will bind their socket and do
+ *     a passive listen, thus the name of the flag. Otherwise the local or
+ *     loopback address will be returned, this is "127.0.0.1" for IPv4 and "::1'
+ *     for IPv6.
+ *   - ...
+ *
+ *
+ * === Returns
+ *
+ * Returns an array of arrays, where each subarray contains:
+ * - address family, a string like "AF_INET" or "AF_INET6"
+ * - port number, the port number for +service+
+ * - host name, either a canonical name for +host+, or it's address in presentation
+ *   format if the address could not be looked up.
+ * - host IP, the address of +host+ in presentation format
+ * - address family, as a numeric value (one of the Socket::AF_* constants).
+ * - socket type, as a numeric value (one of the Socket::SOCK_* constants).
+ * - protocol number, as a numeric value (one of the Socket::IPPROTO_* constants).
+ *
+ * The first four values are identical to what is commonly returned as an
+ * address array, see IPSocket for more information.
+ *
+ * === Examples
+ *
+ * Not all input combinations are valid, and while there are many combinations,
+ * only a few cases are common.
+ *
+ * A typical client will call getaddrinfo with the +host+ and +service+ it
+ * wants to connect to. It knows that it will attempt to connect with either
+ * TCP or UDP, and specifies +socktype+ accordingly. It loops through all
+ * returned addresses, and try to connect to them in turn:
+ *
+ *   addrinfo = Socket::getaddrinfo('www.example.com', 'www', nil, Socket::SOCK_STREAM)
+ *   addrinfo.each do |af, port, name, addr|
+ *     begin
+ *       sock = TCPSocket.new(addr, port)
+ *       # ...
+ *       exit 1
+ *     rescue
+ *     end
+ *   end
+ *
+ * With UDP you don't know if connect suceeded, but if communication fails,
+ * the next address can be tried.
+ *
+ * A typical server will call getaddrinfo with a +host+ of nil, the +service+
+ * it listens to, and a +flags+ of Socket::AI_PASSIVE. It will listen for
+ * connections on the first returned address:
+ *   addrinfo = Socket::getaddrinfo(nil, 'www', nil, Socket::SOCK_STREAM, nil, Socket::AI_PASSIVE)
+ *   af, port, name, addr = addrinfo.first
+ *   sock = TCPServer(addr, port)
+ *   while( client = s.accept )
+ *     # ...
+ *   end

+ * Document-class: StringScanner
+ * 
+ * StringScanner provides for lexical scanning operations on a String.  Here is
+ * an example of its usage:
+ *
+ *   s = StringScanner.new('This is an example string')
+ *   s.eos?               # -> false
+ *   
+ *   p s.scan(/\w+/)      # -> "This"
+ *   p s.scan(/\w+/)      # -> nil
+ *   p s.scan(/\s+/)      # -> " "
+ *   p s.scan(/\s+/)      # -> nil
+ *   p s.scan(/\w+/)      # -> "is"
+ *   s.eos?               # -> false
+ *   
+ *   p s.scan(/\s+/)      # -> " "
+ *   p s.scan(/\w+/)      # -> "an"
+ *   p s.scan(/\s+/)      # -> " "
+ *   p s.scan(/\w+/)      # -> "example"
+ *   p s.scan(/\s+/)      # -> " "
+ *   p s.scan(/\w+/)      # -> "string"
+ *   s.eos?               # -> true
+ *   
+ *   p s.scan(/\s+/)      # -> nil
+ *   p s.scan(/\w+/)      # -> nil
+ *
+ * Scanning a string means remembering the position of a <i>scan pointer</i>,
+ * which is just an index.  The point of scanning is to move forward a bit at
+ * a time, so matches are sought after the scan pointer; usually immediately
+ * after it.
+ *
+ * Given the string "test string", here are the pertinent scan pointer
+ * positions:
+ *
+ *     t e s t   s t r i n g
+ *   0 1 2 ...             1
+ *                         0
+ *
+ * When you #scan for a pattern (a regular expression), the match must occur
+ * at the character after the scan pointer.  If you use #scan_until, then the
+ * match can occur anywhere after the scan pointer.  In both cases, the scan
+ * pointer moves <i>just beyond</i> the last character of the match, ready to
+ * scan again from the next character onwards.  This is demonstrated by the
+ * example above.
+ *
+ * == Method Categories
+ *
+ * There are other methods besides the plain scanners.  You can look ahead in
+ * the string without actually scanning.  You can access the most recent match.
+ * You can modify the string being scanned, reset or terminate the scanner,
+ * find out or change the position of the scan pointer, skip ahead, and so on.
+ * 
+ * === Advancing the Scan Pointer
+ *
+ * - #getch
+ * - #get_byte
+ * - #scan
+ * - #scan_until
+ * - #skip
+ * - #skip_until
+ *
+ * === Looking Ahead
+ *
+ * - #check
+ * - #check_until
+ * - #exist?
+ * - #match?
+ * - #peek
+ *
+ * === Finding Where we Are
+ *
+ * - #beginning_of_line? (#bol?)
+ * - #eos?

-This document discribes about the 'tcltklib' library. Although there
-is the 'tcltk' library (tcltk.rb) under this directory, no description
-in this document (because it is not maintained recently). 
-
-==============================================================
-module TclTklib
-  : Defines methods to do operations which are independed on 
-  : Tcl/Tk interpreters
-
-  module TclTkLib::EventFlag
-    : Defines flags to define taget events on 'do_one_event' methos. 
-    : When to give, please use bit-operator (e.g. WINDOW | DONT_WAIT). 
-
-    [constants]
-       NONE
-         : Is 0. It means "there is no target". But on the real
-         : operation, it is same to ALL.
-
-       WINDOW
-         : 'window' event is processed.
-
-       FILE
-         : 'file' event is processed.
-
-       TIMER
-         : 'timer' event is processed.
-
-       IDLE
-         : 'idle' operation (e.g. 're-draw'; the operations when the
-         : other kinds of events doesn't occur) is processed. 
-
-       ALL
-         : All kinds of events are processed. 
-         : Same to 'WINDOW | FILE | TIMER | IDLE'. 
-
-       DONT_WAIT
-         : Without this flag, 'do_one_event' waits the occurence of 
-         : a target event. With this flag, doesn't wait and returns 
-         : false if there is no target event for processing. 
-
-    [module methods]
-       mainloop(check_root = true)
-         : Starts the eventloop. If 'check_root' is true, this method 
-	 : doesn't return when a root widget exists. 
-         : If 'check_root' is false, doen't return by the other
-         : reasons than exceptions.
-
-      mainloop_watchdog(check_root = true)
-         : On the normal eventloop, some kinds of callback operations 
-         : cause deadlock. To avoid some of such deadlocks, this
-         : method starts an eventloop and a watchdog-thread.
-
-      do_one_event(flag = TclTkLib::EventFlag::ALL | 
-                            TclTkLib::EventFlag::DONT_WAIT)
-         : Do one event for processing. When processed an event, 
-         : returns true. 
-         : If NOT set DONT_WAIT flag, this method waits occurrence of
-         : a target event. 
-         : If set DONT_WAIT flag and no event for processing, returns 
-         : false immediately. 
-         : If $SAFE >= 4,  or $SAFE >= 1 and the flag is tainted, 
-         : force to set DONT_WAIT flag.
-
-      set_eventloop_tick(timer_tick)
-         : Define the interval of thread-switching with an integer
-         : value of mili-seconds. 
-         : Default timer_tick is 0. It means that thread-switching 
-         : is based on the count of processed events. 
-         : ( see 'set_eventloop_weight' method )
-         : However, if the eventloop thread is the only thread, 
-         : timer_tick cannt be set to 0. If 0, then is set to 100 ms 
-         : automatically (see NO_THREAD_INTERRUPT_TIME on tcltklib.c). 
-         : On $SAFE >= 4, cannot call this method. 
-
-      get_eventloop_tick
-         : Get current value of 'timer_tick'
-
-      set_no_event_wait(no_event_wait)
-         : Define sleeping time of the eventloop when two or more 
-         : thread are running and there is no event for processing. 
-         : Default value is 20 (ms).
-         : If the eventloop thread is the only thread, this value is 
-         : invalid.

-         : Get current value of 'no_event_wait'.
-
-      set_eventloop_weight(loop_max, no_event_tick)
-         : Define the weight parameters for the eventloop thread. 
-         : That is invalid when the eventloop is the only thread. 
-         : 'loop_max' is the max events for thread-switching. 
-         : 'no_event_tick' is the increment value of the event count 
-         : when no event for processing (And then, the eventloop thead

-         : 'loop_max == 800' and 'no_event_tick == 10' are defalut.

-         : Define whether the eventloop stops on exception or not. 
-         : If true (default value), stops on exception. 
-         : If false, show a warinig message but ignore the exception.
-         : If nil, no warning message and ignore the excepsion. 
-         : This parameter is sometimes useful when multiple Tk
-         : interpreters are working. Because the only one eventloop 
-         : admins all Tk interpreters, sometimes exception on a
-         : interpreter kills the eventloop thread. Even if such

-         : If is given nil or falsr for the 'option' argument, generates
-         : the Tcl interpreter without Tk library. Then the interpreter 
-         : doesn't need GUI environment. Therefore, even if a window
-         : system doesn't exist or cannot be used, Ruby can control the
-         : Tcl interpreter and the extention libraries loaded on the

-         : interpreter. Default is false. However, if the parent
-         : interpreter is a safe interpreter, the created interpreter is
-         : a safe interpreter (ignore 'safe' argument value). 
-         : If $SAFE >= 4, can create a safe interpreter only. 
-
-      make_safe
-         : Make the interpreter to the safe interpreter, and returns
-         : self. If fail, raise RuntimeError.
-
-      safe?
-         : Check whether the interpreter is the safe interpreter. 
-         : If is the safe interpreter, returns true.

-         : Use this when you need Tk functions after destroying the
-         : root widget. 
-         : On $SAFE >= 4, cannot call this method. 
-
-      _eval(str)
-      _invoke(*args)
-         : Estimates the arguments as a command on the Tk interpreter. 
-         : The argument of _eval is a script of Tcl/Tk.
-         : Each argument of _invoke is a token of one command line of

-         : Because the operation of _invoke doesn't through the
-         : command line parser of Tk interpreter, the cost of
-         : estimation is smaller than _eval. However, auto_load
-         : mechanism of the Tk interpreter doesn't work on _invoke. 
-         : So _invoke can call only the command which already
-         : registered on the interpreter by 'load' command and so on. 
-         : On _eval command, auto_load mechanism words. So if succeed

-
-      _thread_vwait(var_name)
-      _thread_tkwait(mode, target)
-         : 'vwait' or 'tkwait' with thread support. 
-         : The difference from normal 'vwait' or 'tkwait' command is 
-         : doing independent wait from the vwait stack when they are
-         : called on the other thread than the eventloop thread.
-         : In the case of Tcl/Tk's vwait / tkwait, if 2nd vwait /
-         : tkwait is called on waiting for 1st vwait / tkwait, 
-         : returns the order of [2nd]->[1st] regardless of the order

-         : If _thread_vwait / _thread_tkwait is called on the

-         : tkwait. But if called on the other thread than the
-         : eventloop, stops the thread.  And when the wait condition 
-         : is fulfilled, the thread restarts. The meaning of
-         : "independent from the vwait stack" is that the timing of 
-         : restarting is independent from the waiting status of the 
-         : other threads. That is, even if the eventloop thread is 
-         : waiting by vwait and is not fulfilled the condition, 
-         : _thread_vwait completes the waiting when its waiting
-         : condition is fulfilled and the thread which stopped by

-To compile 'tcltklib', you must have Tcl/Tk libraries on your environment. 
-Although 'extconf.rb' script searches Tcl/Tk libraries and header files, 
-sometimes fails to find them. And then, 'tcltklib' cannot be compiled. If 
-Tcl/Tk libraries or header files are installed but are not found, you can 
-give the information by arguments of the 'configure' script. Please give 
-some or all of the following options. 
-
- --with-tcllib=<libname>    (e.g. libtcl8.3.so ==> --with-tcllib=tcl8.3)
- --with-tklib=<libname>     (e.g. libtk8.3.so  ==> --with-tklib=tk8.3)
-
- --enable_tcltk_stubs       (if you force to enable stubs)
-
- --with-tcl-dir=<path> 
-      equal to "--with-tcl-include=<path>/include --with-tcl-lib=<path>/lib"
-
- --with-tk-dir=<path> 
-      equal to "--with-tk-include=<path>/include --with-tk-lib=<path>/lib"

- --with-tcl-lib=<dir>       the directry containts 'libtcl<version>.so'
- --with-tk-lib=<dir>        the directry containts 'libtk<version>.so'
-
-If you forgot to give the options when do 'configure' on toplevel
-directry of Ruby sources, please try something like as the followings.
-
- $ cd ext/tcltklib
- $ rm Makefile
- $ CONFIGURE_ARGS='--with-tcl-include=/usr/local/include/tcl8.3/ --with-tcllib=tcl8.3 --with-tklib=tk8.3 --enable-tcltk_stubs' ruby extconf.rb
-
-
- *** ATTENTION ***
-When your Tcl/Tk libraries are compiled with "pthread support", 
-Ruby/Tk may cause "Hang-up" or "Segmentation Fault" frequently. 
-If you have such a trouble, please try to use the '--enable-pthread' 
-option of the 'configure' command and re-compile Ruby sources. 
-It may help you to avoid this trouble.

+
+This document discribes about the 'tcltklib' library. Although there
+is the 'tcltk' library (tcltk.rb) under this directory, no description
+in this document (because it is not maintained recently). 
+
+==============================================================
+module TclTklib
+  : Defines methods to do operations which are independed on 
+  : Tcl/Tk interpreters
+
+  module TclTkLib::EventFlag
+    : Defines flags to define taget events on 'do_one_event' methos. 
+    : When to give, please use bit-operator (e.g. WINDOW | DONT_WAIT). 
+
+    [constants]
+       NONE
+         : Is 0. It means "there is no target". But on the real
+         : operation, it is same to ALL.
+
+       WINDOW
+         : 'window' event is processed.
+
+       FILE
+         : 'file' event is processed.
+
+       TIMER
+         : 'timer' event is processed.
+
+       IDLE
+         : 'idle' operation (e.g. 're-draw'; the operations when the
+         : other kinds of events doesn't occur) is processed. 
+
+       ALL
+         : All kinds of events are processed. 
+         : Same to 'WINDOW | FILE | TIMER | IDLE'. 
+
+       DONT_WAIT
+         : Without this flag, 'do_one_event' waits the occurence of 
+         : a target event. With this flag, doesn't wait and returns 
+         : false if there is no target event for processing. 
+
+  module TclTkLib::VarAccessFlag
+    : Defines flags to give '_get_variable' and so on. When to give, 
+    : please use bit-operator (e.g. GLOBAL_ONLY | LEAVE_ERR_MSG ). 
+
+    [constants]
+       NONE
+         : Is 0. It means "set no flag". 
+
+       GLOBAL_ONLY
+         : (site Tcl/Tk's man page)
+         : Under normal circumstances the procedures look up 
+         : variables as follows: If a procedure call is active 
+         : in interp, a variable is looked up at the current
+         : level of procedure call. Otherwise, a variable is
+         : looked up first in the current namespace,  then  in
+         : the global namespace. However, if this bit is set
+         : in flags then the variable is looked up only in the
+         : global namespace even if there is a procedure call
+         : active. If both GLOBAL_ONLY and NAMESPACE_ONLY are
+         : given, GLOBAL_ONLY is ignored.
+         :
+         :  *** ATTENTION ***
+         : Tcl7.6 doesn't have namespaces. So NAMESPACE_ONLY 
+         : is defined as 0, and then GLOBAL_ONLY is available
+         : even if flag is (GLOBAL_ONLY | NAMESPACE_ONLY). 
+
+       NAMESPACE_ONLY
+         : (site Tcl/Tk's man page)
+         : Under normal circumstances the procedures look up
+         : variables as follows: If a procedure call is active
+         : in interp, a variable is looked up at the current
+         : level of procedure call. Otherwise, a variable is
+         : looked up first in the current namespace, then in
+         : the global namespace. However, if this bit is set
+         : in flags then the variable is looked up only in the
+         : current namespace even if there is a procedure call
+         : active.

+         :  *** ATTENTION ***
+         : Tcl7.6 doesn't have namespaces. So NAMESPACE_ONLY 
+         : is defined as 0.
+
+       LEAVE_ERR_MSG
+         : (site Tcl/Tk's man page)
+         : If an error is returned and this bit is set in flags, 
+         : then an error message will be left in the interpreter's
+         : result, where it can be retrieved with Tcl_GetObjResult
+         : or Tcl_GetStringResult. If this flag bit isn't set then 
+         : no error message is left and the interpreter's result 
+         : will not be modified.
+
+       APPEND_VALUE
+         : (site Tcl/Tk's man page)
+         : If this bit is set then newValue is appended to the
+         : current value, instead of replacing it. If the variable
+         : is currently undefined, then this bit is ignored.
+
+       LIST_ELEMENT
+         : (site Tcl/Tk's man page)
+         : If this bit is set, then newValue is converted to a
+         : valid Tcl list element before setting (or appending
+         : to) the variable. A separator space is appended before
+         : the new list element unless the list element is going
+         : to be the first element in a list or sublist (i.e. the 
+         : variable's current value is empty, or contains the 
+         : single character ``{'', or ends  in `` }'').

+         : If this bit is set when calling _set_variable and so 
+         : on, var_name argument may contain both an array and an
+         : element name: if the name contains an open parenthesis 
+         : and ends with a close parenthesis, then the value 
+         : between the parentheses is treated as an element name 
+         : (which can have any string value) and the characters
+         : before  the first open parenthesis are treated as the 
+         : name of an array variable. If the flag PARSE_VARNAME
+         : is given, index_name argument should be 'nil' since the 
+         : array and element names are taken from var_name.
+         :
+         :  *** ATTENTION ***
+         : Tcl7.6 doesn't have this flag. So PARSE_VARNAME is

+ActiveTcl is ActiveState's quality-assured distribution of Tcl. 
+
+# see <http://www.activestate.com/Products/ActiveTcl/>
+#     <http://www.tcl.tk/>
+
+If you want to use ActiveTcl binary package as the Tcl/Tk libraries, 
+please use the following configure options.
+
+   --with-tcl-dir=<ActiveTcl_root>
+   --with-tk-dir=<ActiveTcl_root>
+
+And use the followings if you need.
+
+   --with-tcllib=<libname>
+   --with-tklib=<libname>
+   --enable-tcltk-stubs
+
+For example, when you install ActiveTcl-8.4.x to '/usr/local/ActiveTcl', 
+
+   configure --with-tcl-dir=/usr/local/ActiveTcl/  \
+             --with-tk-dir=/usr/local/ActiveTcl/   \
+             --with-tcllib=tclstub8.4              \
+             --with-tklib=tkstub8.4                \
+             --enable-tcltk-stubs
+
+It depends on your environment that you have to add the directory of 
+ActiveTcl's libraries to your library path when execute Ruby/Tk. 
+One of the way is to add entries to TCLLIBPATH environment variable, 
+and one of the others add to LD_LIBRARY_PATH environment variable
+
+Probably, using TCLLIBPATH is better. The value is appended at the 
+head of Tcl's 'auto_path' variable. You can see the value of the 
+variable by using 'Tk::AUTO_PATH.value' or 'Tk::AUTO_PATH.list'.
+
+For example, on Linux, one of the ways is to use LD_LIBRARY_PATH 
+environment variable. 
+-------------------------------------------------------------------------
+ [bash]$ LD_LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH \
+         ruby your-Ruby/Tk-script
+
+ [bash]$ LD_LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH irb
+-------------------------------------------------------------------------
+Based on it, the Tcl interpreter changes auto_path variable's value.
+
+Then, you'll be able to use Tcl/Tk extension libraries included in the
+ActiveTcl package (e.g. call TkPackage.require('BWidget'), and then,
+use functions/widgets of BWidget extention).

+  *** for MacOS X Aqua (Tcl/Tk Aqua) users ***
+
+First of all, please read README.tcltklib to use Tcl/Tk Aqua Framework.
+
+With Tcl/Tk Aqua libraries, current tcltklib somtimes freezes when 
+using Aqua specific dialogs (e.g. Tk.messageBox). 
+This is a known bug of Ruby-1.8.4 release.
+
+When you meet the trouble on your GUI, you'll be able to avoid the trouble 
+by Tcl/Tk's traditional dialogs. 
+If you want to do that, please call some of the following bits of script 
+after "reqruie 'tk'".
+
+=================================================================
+# use a traditional dialog for Tk.chooseColor()
+Tk.ip_eval(<<'EOS')
+    proc ::tk_chooseColor {args} {
+        return [eval tk::dialog::color:: $args]

+# And the format of the menu_info is:
+#   [

+# underline, accelerator, and configs are optional pearameters. 
+# Hashes are OK instead of Arrays. Then the entry type ('command',

+# (e.g. :type=>'cascade'). When type is 'cascade', an array of menu_info
+# is acceptable for 'menu' key (then, create sub-menu).
+#
+# NOTE: (*1)
+#   If you want to make special menus (*.help for UNIX, *.system for Win, 
+#   and *.apple for Mac), append 'menu_name'=>name (name is 'help' for UNIX, 
+#   'system' for Win, and 'apple' for Mac) option to the configs hash of 
+#   menu button/entry information.
+#
+# NOTE: (*2)
+#   If you want to configure a cascade menu, add :menu_config=>{...configs..}
+#   to the configs of the cascade entry.

+  [ current support status of Tcl/Tk extensions ]
+
+  *** RELEASE_DATE of the libraries => see 'tkextlib/version.rb' ***
+
+The following list shows *CURRENT* status when this file was modifyed
+at last. If you want to add other Tcl/Tk extensions to the planed list
+(or change its status position), please request them at the ruby-talk,
+ruby-list, or ruby-dev ML. Although we cannot promise to support your 
+requests, we'll try to do. 
+
+If you want to check that wrapper libraries are ready to use on your 
+environment, please execute 'pkg_checker.rb' with no arguments. The 
+script may give you some hints about that.
+
+
+  ***** IMPORTANT NOTE **********************************************
+
+    'support' means that Ruby/Tk's wrapper libraries are released. 
+    'not support' does *NOT* mean that the extension doesn't work
+    on Ruby/Tk. 
+
+    The version number of each extension means the latest version
+    which is checked its feature. That is, it does NOT means only 
+    version of working. Library files maybe include some features 
+    which is included in the former version but removed from the 
+    latest, and maybe able to support the later version then the 
+    shown version.
+
+    Even if the status of the extension is 'not support', you can 
+    control the functions/widgets of the extension without wrapper 
+    libraries by Tk.tk_call(), Tk.ip_eval(), and so on. 
+
+    If you cannot use installed Tcl/Tk extension, please check the 
+    followings. 
+
+     (1) On your Tcl/Tk, does the extention work?
+
+     (2) Do DLL libraries of the extension exist on DLL load-path?
+         (See also "<ruby archive>/ext/tcltklib/README.ActiveTcl")
+
+     (3) Is the Tcl library directory of the extension included in 
+         library search-path of the Tcl interpreter linked Ruby/Tk?
+
+    The check results may request you to do some setup operations 
+    before using the extension. If so, then please write the step 
+    of setup oprations into the "setup.rb" file in the directory 
+    of the wrapper libraries for the extention (It is the wrapper
+    libraries have the standard structure of the libraries in this 
+    directory). The "setup" file is required before requiring the 
+    Tcl library package (TkPackage.require(<libname>)).

+-----<from "What is tcllib?">----------------------------
+Tcllib is a collection of utility modules for Tcl. These modules provide 
+a wide variety of functionality, from implementations of standard data 
+structures to implementations of common networking protocols. The intent 
+is to collect commonly used function into a single library, which users 
+can rely on to be available and stable.

+#   * Part of tcllib extension
+#   * Provides for a scrollbar to automatically mapped and unmapped as needed
+#
+# (The following is the original description of the library.)
+#
+# This package allows scrollbars to be mapped and unmapped as needed 
+# depending on the size and content of the scrollbars scrolled widget. 
+# The scrollbar must be managed by either pack or grid, other geometry 
+# managers are not supported.
+#
+# When managed by pack, any geometry changes made in the scrollbars parent 
+# between the time a scrollbar is unmapped, and when it is mapped will be 
+# lost. It is an error to destroy any of the scrollbars siblings while the 
+# scrollbar is unmapped. When managed by grid, if anything becomes gridded 
+# in the same row and column the scrollbar occupied it will be replaced by 
+# the scrollbar when remapped.
+#
+# This package may be used on any scrollbar-like widget as long as it 
+# supports the set subcommand in the same style as scrollbar. If the set 
+# subcommand is not used then this package will have no effect.

+# (The following is the original description of the library.)
+#
+# Plotchart is a Tcl-only package that focuses on the easy creation of 
+# xy-plots, barcharts and other common types of graphical presentations. 
+# The emphasis is on ease of use, rather than flexibility. The procedures 
+# that create a plot use the entire canvas window, making the layout of the 
+# plot completely automatic.
+#
+# This results in the creation of an xy-plot in, say, ten lines of code:
+# --------------------------------------------------------------------
+#    package require Plotchart
+#
+#    canvas .c -background white -width 400 -height 200
+#    pack   .c -fill both
+#
+#    #
+#    # Create the plot with its x- and y-axes
+#    #
+#    set s [::Plotchart::createXYPlot .c {0.0 100.0 10.0} {0.0 100.0 20.0}]
+#
+#    foreach {x y} {0.0 32.0 10.0 50.0 25.0 60.0 78.0 11.0 } {
+#        $s plot series1 $x $y
+#    }
+#
+#    $s title "Data series"
+# --------------------------------------------------------------------
+#
+# A drawback of the package might be that it does not do any data management. 
+# So if the canvas that holds the plot is to be resized, the whole plot must 
+# be redrawn. The advantage, though, is that it offers a number of plot and 
+# chart types:
+#
+#    * XY-plots like the one shown above with any number of data series.
+#    * Stripcharts, a kind of XY-plots where the horizontal axis is adjusted 
+#      automatically. The result is a kind of sliding window on the data 
+#      series.
+#    * Polar plots, where the coordinates are polar instead of cartesian.
+#    * Isometric plots, where the scale of the coordinates in the two 
+#      directions is always the same, i.e. a circle in world coordinates 
+#      appears as a circle on the screen.
+#      You can zoom in and out, as well as pan with these plots (Note: this 
+#      works best if no axes are drawn, the zooming and panning routines do 
+#      not distinguish the axes), using the mouse buttons with the control 
+#      key and the arrow keys with the control key.
+#    * Piecharts, with automatic scaling to indicate the proportions.
+#    * Barcharts, with either vertical or horizontal bars, stacked bars or 
+#      bars side by side.
+#    * Timecharts, where bars indicate a time period and milestones or other 
+#      important moments in time are represented by triangles.
+#    * 3D plots (both for displaying surfaces and 3D bars)

+This sample shows how to use a binary sequence between Ruby and Tk. \
+This reads the image data from the file as the binary sequence.
+
+To treat the difference of encodings between on Ruby and on Tk seamlessly, \
+Ruby/Tk converts the encoding of string arguments automatically. \
+I think it is comfortable for users on almost all situations. \
+However, when treats a binary sequence, the convert process makes troubles.
+
+Tk::BinaryString class (subclass of Tk::EncodedString class) is the class \
+to avoid such troubles. Please see the source code of this sample. \
+A Tk::BinaryString instance is used to create the image for the center button.

+(e.g. /usr/local/bin/ruby widget button.rb entry1.rb text.rb )
+You can ommit '.rb' of the sub-scripts
+(e.g. /usr/local/bin/ruby widget button entry1 text )

+If you don't need launcher's main window, give -n option.

+
+Others (browse1, hello, and so on) are standalone scripts.

+#>># This is a whizzlet that does a Rube Goldberg type animation, the
+#>># design of which comes from an New Years e-card from IncrediMail.
+#>># That version had nice sound effects which I eschewed. On the other
+#>># hand, that version was in black and white (actually dark blue and
+#>># light blue) and this one is fully colorized.
+#>>#
+#>># One thing I learned from this project is that drawing filled complex
+#>># objects on a canvas is really hard. More often than not I had to
+#>># draw each item twice--once with the desired fill color but no
+#>># outline, and once with no fill but with the outline. Another trick
+#>># is erasing by drawing with the background color. Having a flood fill
+#>># command would have been extremely helpful.
+#>>#
+#>># Two wiki pages were extremely helpful: Drawing rounded rectangles
+#>># which I generalized into Drawing rounded polygons, and regular
+#>># polygons which allowed me to convert ovals and arcs into polygons
+#>># which could then be rotated (see Canvas Rotation). I also wrote
+#>># Named Colors to aid in the color selection.

+#	Calculate a Knight's tour of a chessboard.

+#	This uses Warnsdorff's rule to calculate the next square each
+#	time. This specifies that the next square should be the one that
+#	has the least number of available moves.
+#
+#	Using this rule it is possible to get to a position where
+#	there are no squares available to move into. In this implementation
+#	this occurs when the starting square is d6.
+#
+#	To solve this fault an enhancement to the rule is that if we
+#	have a choice of squares with an equal score, we should choose
+#	the one nearest the edge of the board.
+#
+#	If the call to the Edgemost function is commented out you can see
+#	this occur.
+#
+#	You can drag the knight to a specific square to start if you wish.
+#	If you let it repeat then it will choose random start positions
+#	for each new tour.

 The sash between the two coloured windows below can be used to divide the area between them.  Use the left mouse button to resize without redrawing by just moving the sash, and use the middle mouse button to resize opaquely (always redrawing the windows in each position.)
 If your Tk library linked to Ruby doesn't include a 'panedwindow', this demo doesn't work. Please use later version of Tk which supports a 'panedwindow'.

 The sash between the two scrolled windows below can be used to divide the area between them.  Use the left mouse button to resize without redrawing by just moving the sash, and use the middle mouse button to resize opaquely (always redrawing the windows in each position.)
 If your Tk library linked to Ruby doesn't include a 'panedwindow', this demo doesn't work. Please use later version of Tk which supports a 'panedwindow'.

+Ttk is the new Tk themed widget set, \
+and one widget that is available in themed form is the menubutton. \
+Below are some themed menu buttons \
+that allow you to pick the current theme in use. \
+Notice how picking a theme changes the way \
+that the menu buttons themselves look, \
+and that the central menu button is styled differently \
+(in a way that is normally suitable for toolbars). \
+However, there are no themed menus; the standard Tk menus were judged \
+to have a sufficiently good look-and-feel on all platforms, \
+especially as they are implemented as native controls in many places.

+#	Calculate a Knight's tour of a chessboard.
+#
+#	This uses Warnsdorff's rule to calculate the next square each
+#	time. This specifies that the next square should be the one that
+#	has the least number of available moves.
+#
+#	Using this rule it is possible to get to a position where
+#	there are no squares available to move into. In this implementation
+#	this occurs when the starting square is d6.
+#
+#	To solve this fault an enhancement to the rule is that if we
+#	have a choice of squares with an equal score, we should choose
+#	the one nearest the edge of the board.
+#
+#	If the call to the Edgemost function is commented out you can see
+#	this occur.
+#
+#	You can drag the knight to a specific square to start if you wish.
+#	If you let it repeat then it will choose random start positions
+#	for each new tour.

+
+USAGE = <<EOT
+--- WHAT IS ---
+You can write comments on the loaded image, and save it as a Postscipt 
+file (original image file is not modified). Each comment is drawn as a 
+set of an indicator circle, an arrow, and a memo text. See the following 
+how to write comments.
+This can save the list of memo texts to another file. It may useful to 
+search the saved Postscript file by the comments on them.
+This may not support multibyte characters (multibyte texts are broken on 
+a Postscript file). It depends on features of canvas widgets of Tcl/Tk 
+libraries linked your Ruby/Tk. If you use Tcl/Tk8.0-jp (Japanized Tcl/Tk),
+you can (possibly) get a Japanese Postscript file.
+
+--- BINDINGS ---
+* Button-1 : draw comments by following steps
+    1st - Set center of a indicator circle.
+    2nd - Set head position of an arrow.
+    3rd - Set tail position of an arrow, and show an entry box.
+          Input a memo text and hit 'Enter' key to entry the comment.
+
+* Button-2-drag : scroll the canvas
+
+* Button-3 : when drawing, cancel current drawing
+
+* Double-Button-3 : delete the clicked comment (text, arrow, and circle)

+# Demonstration of custom classes.
+#
+# The Tile button doesn't have built-in support for autorepeat.
+# Instead of adding -repeatdelay and -repeatinterval options,
+# and all the extra binding scripts required to deal with them,
+# we create a custom widget class for autorepeating buttons.
+#
+# Usage:
+#	ttk::button .b -class Repeater [... other options ...]
+#
+# TODO:
+#	Use system settings for repeat interval and initial delay.
+#
+# Notes:
+#	Repeater buttons work more like scrollbar arrows than
+#	Tk repeating buttons: they fire once immediately when
+#	first pressed, and $State(delay) specifies the initial 
+#	interval before the button starts autorepeating.
+#
+

+# $Id$
+#
+# Demonstration of custom widget styles.
+#
+
+#
+# ~ BACKGROUND
+#
+# Checkbuttons in toolbars have a very different appearance 
+# than regular checkbuttons: there's no indicator, they
+# "pop up" when the mouse is over them, and they appear sunken
+# when selected.
+# 
+# Tk added partial support for toolbar-style buttons in 8.4 
+# with the "-overrelief" option, and TIP #82 added further
+# support with the "-offrelief" option.  So to get a toolbar-style 
+# checkbutton, you can configure it with:
+#
+# checkbutton .cb \
+#     -indicatoron false -selectcolor {} -relief flat -overrelief raised
+#
+# Behind the scenes, Tk has a lot of rather complicated logic
+# to implement this checkbutton style; see library/button.tcl,
+# generic/tkButton.c, and the platform-specific files unix/tkUnixButton.c
+# et al. for the full details.
+#
+# The tile widget set has a better way: custom styles.
+# Since the appearance is completely controlled by the theme engine,
+# we can define a new "Toolbutton" style and just use:
+#
+# checkbutton .cb -style Toolbutton
+#
+#
+# ~ DEMONSTRATION
+#
+# The tile built-in themes (default, "alt", windows, and XP) 
+# already include Toolbutton styles.  This script will add
+# them to the "step" and "blue" themes as a demonstration.
+#
+# (Note: Pushbuttons and radiobuttons can also use the "Toolbutton" 
+# style; see demo.tcl.)
+#
+
+style theme settings "step" {
+
+#
+# First, we use [style layout] to define what elements to
+# use and how they're arranged.  Toolbuttons are pretty
+# simple, consisting of a border, some internal padding,
+# and a label.  (See also the TScrollbar layout definition 
+# in demos/blue.tcl for a more complicated layout spec.)
+#
+    style layout Toolbutton {
+        Toolbutton.background
+        Toolbutton.border -children {
+            Toolbutton.padding -children {
+                Toolbutton.label
+            }
+        }
+    }
+
+# (Actually the above isn't strictly necessary, since the same layout 
+# is defined in the default theme; we could have inherited it 
+# instead.)
+#
+# Next, specify default values for element options.
+# For many options (like -background), the defaults
+# inherited from the parent style are sufficient.
+#
+    style default Toolbutton -width 0 -padding 1 -relief flat -borderwidth 2
+
+#
+# Finally, use [style map] to specify state-specific 
+# resource values.  We want a flat relief if the widget is
+# disabled, sunken if it's selected (on) or pressed, 
+# and raised when it's active (the mouse pointer is
+# over the widget).  Each state-value pair is checked
+# in order, and the first matching state takes precedence.
+#
+    style map Toolbutton -relief {
+	disabled 	flat
+    	selected	sunken  
+	pressed 	sunken  
+	active		raised
+    }
+}
+
+#
+# Now for the "blue" theme.  (Since the purpose of this
+# theme is to show what *can* be done, not necessarily what
+# *should* be done, the following makes some questionable
+# design decisions from an aesthetic standpoint.)
+#
+if {![catch {package require tile::theme::blue}]} {
+style theme settings "blue" {
+
+    #
+    # Default values:
+    #
+    style default Toolbutton \
+    	-width 0 -relief flat -borderwidth 2 \
+	-background #6699CC -foreground #000000 ;
+
+    #
+    # Configure state-specific values for -relief, as before:
+    #
+    style map Toolbutton -relief {
+	disabled 	flat
+    	selected	sunken  
+	pressed 	sunken  
+	active		raised
+    } 
+
+    #
+    # Adjust the -padding at the same time, to enhance
+    # the raised/sunken illusion:
+    #
+    style default Toolbutton -padding 4
+    style map Toolbutton -padding {
+	disabled	{4}
+	selected	{6 6 2 2}
+	pressed		{6 6 2 2}
+	active		{2 2 6 6}
+    }
+
+    #
+    # ... and change the foreground and background colors
+    # when the mouse cursor is over the widget:
+    #
+    style map Toolbutton -background {
+	active  	#008800
+    } -foreground {
+	active  	#FFFFFF
+    }
+}
+
+}
+
+#
+# ~ A final note:  
+#
+# TIP #82 also says: "When -indicatoron is off and the button itself
+# is on, the relief continues to be hard-coded to sunken. For symmetry,
+# we might consider adding another -onrelief option to cover this
+# case. But it is difficult to imagine ever wanting to change the
+# value of -onrelief so it has been omitted from this TIP.
+# If there as strong desire to have -onrelief, it can be added later."
+# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+#
+# The Tile project aims to make sure that this never needs to happen.

+before you start to think it's a government hoax. <A HREF="http://server51.freshmeat.net/">Server 51</A> is our new hosting service for Open Source projects, based on Super Cool Space Alien Technology(TM). We hadn't planned to announce it quite so soon, and it's still in the alpha stage as we work day and night at integrating SCSAT with our terrestrial systems, but feel free to take a look around and see what's going on. When we're out of the testing stage and ready to make room for your project, we'll send word via your implants. Be listening.

+<DIV ALIGN="justify"><P>RabbIt is the mutating, caching webproxy which is used to speed up surfing over slow links like modems. It does this by removing advertising and background images and scaling down images to low quality JPEGs. RabbIT is written in Java and should be able to run on any platform. It does depend upon an image converter if imagescaleing is on. The recommended image converter is "convert" from the ImageMagick package.</DIV>
+<P><B>Changes:</B> Fixes have been made for a few bugs concerning keep alive and the HTTP response header, a bug with NT and cache directories, a bug concerning requests without a response body, a bug in GZIPHandler that caused it to not gzip already compressed (gzip or compress) streams, a bug in HTTPHeader regarding response phrases that are multiline, and a few bugs in ImageHandler and NCache. GZIPHandler has been built as an intermediate(*) to FilterHandler (this means that it is possible to gzip text/plain, etc., without filtering those streams) uuencoding has been added to the Coder, RabbIT now uses HTTP/1.1, HTMLParser now compiles cleanly with Jikes, and GeneralHeader has been created to allow for HTTPFooter (which is useful when sending chunked data).

+#  TkTextIO class :: handling I/O stream on a TkText widget
+#                             by Hidetoshi NAGAI (nagai@ai.kyutech.ac.jp)
+#
+#  NOTE: TkTextIO supports 'character' (not 'byte') access only. 
+#        So, for example, TkTextIO#getc returns a character, TkTextIO#pos 
+#        means the character position, TkTextIO#read(size) counts by 
+#        characters, and so on.
+#        Of course, it is available to make TkTextIO class to suuport 
+#        'byte' access. However, it may break multi-byte characters. 
+#        and then, displayed string on the text widget may be garbled.
+#        I think that it is not good on the supposed situation of using 
+#        TkTextIO.
