Useful gem: utility_belt

[Jeremy Thurgood]

I recently discovered a very useful little Ruby gem for making life
easier in irb: http://utilitybelt.rubyforge.org/

Simply install it (gem install utility_belt), require 'rubygems' and
'utility_belt' in your .irbrc and watch the magic happen.

I find it particularly useful for the readline-style history searching
and output colouring.
