Geocaching download helper tool
The gccom.py script can be used to download various resources from http://www.geocaching.com with your login-account. That means you can easily download LOC/GPX/whatever files automatically with a script. There's virtually no limitation due to its cookie-export feature. So you can export the logged-in cookie and use it in wget (for example). Wget will then download the pages as if you were logged into them on the webbrowser.
Geocaching statistics tool
The gcstats.py script can be used to automatically generate detailled statistics of a Geocaching.com account. The tool depends on gccom.py .
Coordinate conversion tool
Geoconv.py is a tool I use in-field while geocaching to convert between various coordinate formats.
Example usage:

ROT en/decrypt tool

Geo-alphabet conversion tool
