Hi Eric

You may want to give CommandLine a try.
From the examples you give, this is how I would write an app:

require 'rubygems'
require 'commandline'

class MyApp < CommandLine::Application
  def initialize
    # Mandatory argument
    option :names =3D> %w(--require -r),
               :opt_description =3D> "Require the LIBRARY "+
                                            "before executing your script",
               :arg_description =3D> "LIBRARY",
               :opt_found =3D> get_arg,
               :opt_not_found =3D> required

    option :names =3D> %w(--inplace -i),
               :arity =3D> [0,1],
               :opt_description =3D> "Edit ARGV files in place",
               :arg_description =3D> "[EXTENSION]",
               :opt_found =3D> get_arg,
  end

  def main
    #put your code here
    p opts
  end
end#class MyApp

I don't know what #on_tail does either.
