====== loc2gpx script ======
This perl script will convert a geocaching.com LOC file to a Garmin GPX file.  Both files are XML, and writing this has renewed my hatred for XML as a bloated overcomplex format ill suited for 99% of the tasks put to it.

<file>
#!/usr/bin/perl

use strict;

use XML::Parser;
 
# initialize parser and read the file
my $parser = new XML::Parser( Style => 'Tree' );
my $tree = $parser->parsefile( shift @ARGV );

my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = gmtime();
my $timeString = sprintf("%04d-%02d-%02dT%02d:%02d:%02dZ",$year+1900,$mon+1,$mday,$hour,$min,$sec);

print <<EOL;
