Library for command line option analysis.
features:
(1) It is possible <option switch of a short form and a long form> to
exist together. It is also possible in one to bring the switch of
a short form together.
(2) It is possible to write bringing specification and the handler of
the switch together respectively in one place.
(3) The argument of the switch is converted into the class which
automatically specifies it.
(4) The option summary can be made.
(5) The option can be added on the way later.

# == OptionParser
#
# === Introduction
#
# OptionParser (in optparse.rb) is a library 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 example below.
#
# === Class tree
#
# - OptionParser:: front end
# - OptionParser::Switch:: each switches
# - OptionParser::List:: options list
# - OptionParser::ParseError:: errors on parsing
# - OptionParser::AmbiguousOption
# - OptionParser::NeedlessArgument
# - OptionParser::MissingArgument
# - OptionParser::InvalidOption
# - OptionParser::InvalidArgument
# - OptionParser::AmbiguousArgument

# === Example
#
# The following example is a complete Ruby program. You can run it and see the
# effect of specifying various options.

# require 'optparse'
# require 'optparse/time'
# require 'ostruct'
# require 'pp'

# # Return a structure describing the options.
# #

# # We set default values here.

# opts = OptionParser.new do |opts|
# opts.banner = "Usage: example.rb [options]"
#
# opts.separator ""
# opts.separator "Specific options:"
#
# # Mandatory argument.
# opts.on("-r", "--require LIBRARY",
# "Require the LIBRARY before executing your script") do |lib|
# options.library << lib

# "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.
