Usage:
	`basename $PROGNAME` [options] address citystate_or_zip [country]

		Convert (geocode) a street address into a latitude/longitude.

	`basename $PROGNAME` [options] tele-phone-number

		Convert (geocode) a phone number into a latitude/longitude.

	In either case, the output can be formatted to any of the output
	file types that gpsbabel supports, or directly imported into the
	GpsDrive MySQL waypoint database.

Requires:
	curl		http://curl.haxx.se/
	gpsbabel	http://gpsbabel.sourceforge.net/

Options:
	-o format	Output format, -o? for possibilities [$OUTFMT]
			plus "gpsdrive.sql" for direct insertion into MySQL DB
			plus "latlon" for just Lat<tab>Long.
			plus "map" to display a map.
	-n name		The waypoint name, e.g. Bob's House.  The default
			is the street address.
	-s		Output shortened names (a gpsbabel option)
	-t type		The waypoint type, e.g. house, cache, bar [$CODETYPE]
	-q		Quiet. Do not output address confirmation on stderr.
	-S		Alias for -o gpsdrive.sql
	-a		For SQL, delete existing record only if it matches
			all fields.  Otherwise, delete it if it matches
			just the name and the type. 
	-D level	Debug level
	-U		Retrieve latest version of this script

Countries:
	us, ca, fr, de, it, es, uk

Examples:
	\$ geo-code "123 AnyStreet" 12345 
	123AnyStreet 42.81020 -73.95070 new

	\$ geo-code -t house "123 AnyStreet" 12345 
	123AnyStreet 42.81020 -73.95070 house

	\$ geo-code -n "Bob's House" -t house "123 AnyStreet" 12345 
	BobsHouse 42.81020 -73.95070 house

	\$ geo-code -S -n "Bob" -t house "123 AnyStreet" 12345 
	[waypoint is added to GpsDrive MySQL database]

	\$ geo-code 901-555-1212 
	123AnyStreet 42.81020 -73.95070 new
