Rails - Nov 2008 - Reverse keys and values in a hash

Hello all,

This is more of a ruby question than a rails question, but I''m
wondering if it''s possible to reverse the keys and values in a hash.

I''m using a hash to map fields from one component of my app to
another, and sometimes the data needs to go "the other way"...

Thanks!
