+# = pathname.rb
+#
+# Object-Oriented Pathname Class
+#
+# Author:: Tanaka Akira <akr@m17n.org>
+# Documentation:: Author and Gavin Sinclair
+#
+# For documentation, see class Pathname.
+#
+# <tt>pathname.rb</tt> is distributed with Ruby since 1.8.0.
+#
+
+require 'pathname.so'
+
+#
+# == Pathname
+#
+# Pathname represents a pathname which locates a file in a filesystem.
+# The pathname depends on OS: Unix, Windows, etc.
+# Pathname library works with pathnames of local OS.
+# However non-Unix pathnames are supported experimentally.
+#
+# It does not represent the file itself.
+# A Pathname can be relative or absolute. It's not until you try to
+# reference the file that it even matters whether the file exists or not.
+#
+# Pathname is immutable. It has no method for destructive update.
+#
+# The value of this class is to manipulate file path information in a neater
+# way than standard Ruby provides. The examples below demonstrate the
+# difference. *All* functionality from File, FileTest, and some from Dir and
+# FileUtils is included, in an unsurprising way. It is essentially a facade for
+# all of these, and more.
+#
+# == Examples
+#
+# === Example 1: Using Pathname
+#
+# require 'pathname'
+# pn = Pathname.new("/usr/bin/ruby")
+# size = pn.size # 27662
+# isdir = pn.directory? # false
+# dir = pn.dirname # Pathname:/usr/bin
+# base = pn.basename # Pathname:ruby
+# dir, base = pn.split # [Pathname:/usr/bin, Pathname:ruby]
+# data = pn.read
+# pn.open { |f| _ }
+# pn.each_line { |line| _ }
+#
+# === Example 2: Using standard Ruby
+#
+# pn = "/usr/bin/ruby"
+# size = File.size(pn) # 27662
+# isdir = File.directory?(pn) # false
+# dir = File.dirname(pn) # "/usr/bin"
+# base = File.basename(pn) # "ruby"
+# dir, base = File.split(pn) # ["/usr/bin", "ruby"]
+# data = File.read(pn)
+# File.open(pn) { |f| _ }
+# File.foreach(pn) { |line| _ }
+#
+# === Example 3: Special features
+#
+# p1 = Pathname.new("/usr/lib") # Pathname:/usr/lib
+# p2 = p1 + "ruby/1.8" # Pathname:/usr/lib/ruby/1.8
+# p3 = p1.parent # Pathname:/usr
+# p4 = p2.relative_path_from(p3) # Pathname:lib/ruby/1.8
+# pwd = Pathname.pwd # Pathname:/home/gavin
+# pwd.absolute? # true
+# p5 = Pathname.new "." # Pathname:.
+# p5 = p5 + "music/../articles" # Pathname:music/../articles
+# p5.cleanpath # Pathname:articles
+# p5.realpath # Pathname:/home/gavin/articles
+# p5.children # [Pathname:/home/gavin/articles/linux, ...]
+#
+# == Breakdown of functionality
+#
+# === Core methods
+#
+# These methods are effectively manipulating a String, because that's
+# all a path is. Except for #mountpoint?, #children, #each_child,
+# #realdirpath and #realpath, they don't access the filesystem.
+#
+# - +
+# - #join
+# - #parent
+# - #root?
+# - #absolute?
+# - #relative?
+# - #relative_path_from
+# - #each_filename
+# - #cleanpath
+# - #realpath
+# - #realdirpath
+# - #children
+# - #each_child
+# - #mountpoint?
+#
+# === File status predicate methods
+#
+# These methods are a facade for FileTest:
+# - #blockdev?
+# - #chardev?
+# - #directory?
+# - #executable?
+# - #executable_real?
+# - #exist?
+# - #file?
+# - #grpowned?
+# - #owned?
+# - #pipe?
+# - #readable?
+# - #world_readable?
+# - #readable_real?
+# - #setgid?
+# - #setuid?
+# - #size
+# - #size?
+# - #socket?
+# - #sticky?
+# - #symlink?
+# - #writable?
+# - #world_writable?
+# - #writable_real?
+# - #zero?
+#
+# === File property and manipulation methods
+#
+# These methods are a facade for File:
+# - #atime
+# - #ctime
+# - #mtime
+# - #chmod(mode)
+# - #lchmod(mode)
+# - #chown(owner, group)
+# - #lchown(owner, group)
+# - #fnmatch(pattern, *args)
+# - #fnmatch?(pattern, *args)
+# - #ftype
+# - #make_link(old)
+# - #open(*args, &block)
+# - #readlink
+# - #rename(to)
+# - #stat
+# - #lstat
+# - #make_symlink(old)
+# - #truncate(length)
+# - #utime(atime, mtime)
+# - #basename(*args)
+# - #dirname
+# - #extname
+# - #expand_path(*args)
+# - #split
+#
+# === Directory methods
+#
+# These methods are a facade for Dir:
+# - Pathname.glob(*args)
+# - Pathname.getwd / Pathname.pwd
+# - #rmdir
+# - #entries
+# - #each_entry(&block)
+# - #mkdir(*args)
+# - #opendir(*args)
+#
+# === IO
+#
+# These methods are a facade for IO:
+# - #each_line(*args, &block)
+# - #read(*args)
+# - #binread(*args)
+# - #readlines(*args)
+# - #sysopen(*args)
+#
+# === Utilities
+#
+# These methods are a mixture of Find, FileUtils, and others:
+# - #find(&block)
+# - #mkpath
+# - #rmtree
+# - #unlink / #delete
+#
+#
+# == Method documentation
+#
+# As the above section shows, most of the methods in Pathname are facades. The
+# documentation for these methods generally just says, for instance, "See
+# FileTest.writable?", as you should be familiar with the original method
+# anyway, and its documentation (e.g. through +ri+) will contain more
+# information. In some cases, a brief description will follow.
