def help_screen
  <<-HELP
  Usage: echo '1+1' | hylite

    Syntax Highlighting for Scripters.

    Finds an existing syntax highlighting tool (rouge, coderay, pygments),
    and uses that to highlight the code.

  Options:
    -h        This help screen
    -l LANG   Set the language (defaults to Ruby)

  Examples:
    Set the language to JavaScript
    $ echo 'function alphabet() { console.log("abc"); }' | hylite -l javascript

    Add syntax highlighting to `cat`
    $ cat lib/hylite.rb | hylite

    Highlight sassy style sheets
    $ cat app/assets/stylesheets/site.css.scss | hylite -l scss
