First off awesome little util.

One Issue: I get an "invalid multibyte char (US-ASCII) (SyntaxError)" on a pretty standard OSX install. May want to think about looking for support for char and replacing with something like "-" for the lines. Once I changed that in source.rb everything worked great.
