# this feels weird, but there's some magic here. Ruby knows where 'rubygems' is without you having to explain it with an exact path.

# now you can you just flat-out require ANY gem you have installed! like
require 'pony'

# all of the sudden you have this really cool ruby library called 'pony' in your application's object space! And you can do shit like this:

Pony.mail({
