This is gpsdisplay, a small application using OSM data in a PostGIS database
(as usual named "gis") and rendering them via Mapnik. It'll read the current
location from GPSD, using DBus' system bus to access it.

Keyboard control:

	Up:	Move card up.
	Down:	Move card down.
	Left:	Move card left.
	Right:	Move card right.
	Plus:	Zoom into card.
	Minus:	Zoom out of card.
	Dot:	Force a redraw right here, right now.
	G:	Enable/disable location updates from GPSD, useful
		in case you want to use cursor control to move
		around in the map.
	P:	Add a PoI to the GPX file IFF --gpx was given at
		startup time.
	B:	Add a call to the OpenStreetBug submit script.
		(Requires --bug-file and --bug-user.)
