+# == 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.
+#
+# === 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.

+#
+# # 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('.')

+ # "--switch"

+ # [Argument style and description:]

+ # "=[OPTIONAL]"
+ #
+ # [Description:]
