David,
Looks great....Now the stupid question. How do I use it?

Should I place this in TextMate as a snippet and then type in a line of  
regexp to test and run the rx_helper over it, or install this a as a  
command within the ruby bundle. Alternately, should I have my file open  
in textmate and then write my rexexp in the "filter through command"  
after calling rx_helper.

Thanks for the work, and the time to explain its use

Robert
