Patch to Python's bundled CGIHTTPServer.py (from Python 2.7) to run Perl scripts. Useful for serving e.g. AWStats files. Copy `Python27/lib/CGIHTTPServer.py` out, apply the patch and run with `python CGIHTTPServer.py` in `wwwroot`. Then open http://localhost:8000/cgi-bin/awstats.pl?config=example.com in browser.
