"""
This script parses a geocaching.loc file and produces GPX files suitable
for loading into a GPS unit.

Usage:

    $ ./loc2gpx geocaching.log


It will createa a GPX file for each item in the .loc file.  The
filenames are the geocache codes.  This is consistent with what
geocaching.com uses when you "Send to GPS".
