title: configuration file for a standalone ruby script
body: <p>I have a ruby script that runs on a linux server. Its not using rails or anything. Its basically a commandline ruby script that can be passed arguments like this: <code>./ruby_script.rb arg1 arg2</code></p>
  
  <p>How can I abstract away the arguments into a configuration file such as a yaml file or something? Can you provide an example of how this can be done? </p>
  
  <p>Thank you in advance.</p>
