RAA - ropt

-- Homepage and document are JAPANESE ONLY now. --

ropt is command-line option parser for Ruby, easy but useful enough.

example:
----------------------------------------------------------------------------
opt = ROpt.parse(ARGV, "ab:c::", "long-a", "long-b:", "long-c::") || usage

puts("-a specified.") if opt[:a]
puts("-b is #{opt[:b].inspect}") if opt[:b]
puts("-c are #{opt[:c].inspect}") unless opt[:c].empty?

puts("--long-a specified.") if opt['long-a']
puts("--long-b is #{opt['long-b'].inspect}") if opt['long-b']
puts("--long-c are #{opt['long-c'].inspect}") unless opt['long-c'].empty?

puts("Rest arguments: #{opt.args.inspect}") unless opt.args.empty?
