ruby -rubygems
You know, I’ve always wondered why requiring a library on the command line is ruby -r library but you can require rubygems with ruby -rubygems. Here’s why:
[rubygems-1.3.5] cat lib/ubygems.rb
# This file allows for the running of rubygems with a nice
# command line look-and-feel: ruby -rubygems foo.rb

require 'rubygems'
Nice hack.
