A pretty good article, though:
  1. It would be nice if it mentioned optparse, which is a little
     cleaner than getoptlong for what the author is doing.
  2. Using "while line = gets do" is just as clean as "while gets", but
     doesn't require the use of $_.  I suspect the author came from a
     perl background.
  3. I wish he'd mentioned the option of using #!/usr/bin/env ruby
     instead of #!/usr/local/bin/ruby.
