GetOptions - Yet another command line argument parser for Ruby. Inspired  
by Perl’s Getopt::Long module, the GetOptions module provides a fairly  
powerful POSIX-ish option parser that is very easy to learn and use.

## A quick and dirty example…

$ cat example.rb  
require ‘getoptions’

opt = GetOptions.new(%w(help debug! verbose+ prefix:s size=i  
host=@s))  
p opt

–  
$ ./example.rb --help  
:help: true

$ ./example.rb --debug  
:debug: true

$ ./example.rb --no-debug  
:debug: false

$ ./example.rb -vvvvv  
:verbose: 5

$ ./example.rb -vv --verbose  
:verbose: 3

$ ./example.rb --pre  
:prefix: nil

$ ./example.rb --pre myprefix  
:prefix: “myprefix”

$ ./example.rb --size 5  
:size: 5

$ ./example.rb --host foo bar baz  
:host: [“foo”, “bar”, “baz”]

Give it a whirl and let me know what you think.

Enjoy,
