Where's my blasted gems?

If you’re anything like me, and you keep forgetting whereabouts your gems are installed, use the following command:

gem environment

This will pop up a handy list like this:

RubyGems Environment:
- VERSION: 0.9.4 (0.9.4)
- INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.8
- GEM PATH:
- /usr/local/lib/ruby/gems/1.8
- REMOTE SOURCES:
- http://gems.rubyforge.org

Your gems are nicely tucked away within your GEM PATH directory
