+   (description "Navit is a car navigation system with a routing engine.
+
+It is meant to work with touchscreen devices, but it also works
+without a touchscreen. It also supports text to speech.
+
+It can be configured extensively through its own configuration file
+format. For instance we can configure the graphical interface, and
+which map data is to be displayed at which zoom level.
+
+It supports different routing profiles: bike, car, car_avoid_toll,
+car_pedantic, car_shortest, horse, pedestrian, truck.
+
+It can use gpsd or NMEA GPS directly to get position data. It also
+works without GPS: in this case users can also enter position data
+directly.
+
+It can also be used to log GPS data to files using the GPX or NMEA
+formats, or to replay NMEA data.
+
+For maps, it can uses its own \"binfile\" map format, or Garmin map
+file format, and data from OpenStreetMap, Garmin maps, Marco Polo
+Grosser Reiseplaner, Routeplaner Europa 2007, Map + Route.")
