testing regular expressions

I discovered Christof Hoeke’s retest program today. This is a very slick use of Python’s standard library HTTP server module to package an AJAX app for interactively testing out regular expressions. I used to have a Tkinter app that did something similar, but Christof’s is much lighter weight.

Now I need to figure out how to package it to run as an app when I double click on it in the Finder, instead of opening the .py file in an editor.
