Heel is a small static web server for use when you need a quick web server
for a directory. Once the server is running, heel will use launchy
(http://copiousfreetime.rubyforge.org/launchy/) to open your browser at the
URL of your document root.  Heel is built using
Rack(http://rack.rubyforge.org) and Thin (http://code.macournoyer.com/thin/)
