This looks fun!

Although I get an error:

 rush
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in
`require__': No such file to load -- options (LoadError)

from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in

from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in
`require'
        from /usr/bin/rush:58



I installed rush with 'sudo ruby setup.rb'.

Guillaume.
