NAME
	`basename $PROGNAME` - Outputs a list of submitted but unapproved caches

SYNOPSIS
	`basename $PROGNAME` [options]

	`basename $PROGNAME` [options] lat lon

DESCRIPTION
	Outputs a list of submitted but unapproved caches.  This script
	first finds the cache number of the most recently submitted cache,
	anywhere in the world. Then, beginning "-n num" ($NUM) caches before
	that, it fetches the LOC information for caches that have been
	submitted but are not yet (and may never be) approved.  It filters
	these caches to the specified radius around your lat/lon.

	The exploit that makes this possible is that the LOC info is returned
	even though the caches aren't approved.

	The amount of information available for these caches is very limited.
	The GC id, cache name and owner, and lat/lon are all that you get.

	It would be foolish, and unethical, to search for these caches
	before they are approved.  They could be puzzles, multis, virtuals --
	there is no way to know.  But, you might use this information to
	keep a closer vigil on new approvals.  Whether that is ethical or
	not is up to you.  I'm just the toolsmith -- if a tool *can* be
	written, I'm inclined to write it.  Kinda like a gun maker.

	Another use is to check up on your approver, to see how long
	approvals are taking.

	IMPORTANT: The -r radius flag limits the output to your area!
	Otherwise, this command will take a long time to run.

OPTIONS
	-c		Remove cookie file when done
	-n num		Search within the last 'num' caches [$NUM]
	-s		Output short names for the caches (gpsbabel option)
	-r radius	Show only caches within radius (e.g. -r 25M) [$RADIUS]

	-u username	Username for http://www.geocaching.com
	-p password	Password for http://www.geocaching.com
	-o format	Output format, -o? for possibilities [$OUTFMT]
			plus "gpsdrive.sql" for direct insertion into MySQL DB
			plus "map[,geo-map-opts]" to display a geo-map.
	-O filename	Output file, if not stdout
	-S              Alias for -o gpsdrive.sql
        -d              For -S, just delete selected records
        -P              For -S, purge all records of type -t $SQLTAG*
	-t type		For -ogpsdrive.sql, the waypoint type [$SQLTAG]
	-D lvl		Debug level [$DEBUG]
	-U		Retrieve latest version of this script

	Defaults can also be set with variables in file \$HOME/.georc:

	    PASSWORD=password;  USERNAME=username;   MOC=0|1;
	    LAT=latitude;       LON=logitude;
	    NUM=num;            OUTFMT=format;       BABELFLAGS=-s;
