I'm trying to familiarize myself with the Tkinter and ttk libraries, so I built a simple regex tester with them. Cool bonus feature of a button that opens the docpage on regex, too.
Only command line option is a --debug flag to, well, enable debugging.

Tip: use chmod +x regextester.py to run the program as an executeable
