+NavIT
+=====
+
+Navit is a open source (GPL) car navigation system with routing engine.
+
+It's modular design is capable of using vector maps of various formats
+for routing and rendering of the displayed map. It's even possible to
+use multiple maps at a time.
+
+The GTK+ or SDL user interfaces are designed to work well with touch
+screen displays. Points of Interest of various formats are displayed
+on the map.
+
+The current vehicle position is either read from gpsd or directly from
+NMEA GPS sensors.
+
+The routing engine not only calculates an optimal route to your
+destination, but also generates directions and even speaks to you.
+
+Navit currently speaks 27 languages :
+- Brazilian Portuguese
+- Bulgarian
+- Chinese (Hong Kong)
+- Czech
+- Danish
+- Dutch
+- English
+- Estonian
+- Finnish
+- French
+- German
+- Hebrew

+Maps:
+=====
+
+The best navigation system is useless without maps. Those three maps
+are known to work:
+
+- OpenStreetMaps : display, routing, but street name search isn't complete
+ (see http://wiki.navit-project.org/index.php/OpenStreetMaps )
+
+- Grosser Reiseplaner and compliant maps : full support
+ (see http://wiki.navit-project.org/index.php/European_maps )
+
+- Garmin maps : display, routing, search is being worked on
+ (see http://wiki.navit-project.org/index.php/Garmin_maps )
+
+
+GPS Support:
+============
+
+Navit read the current vehicle position :
+- directly from a file
+- from gpsd (local or remote)
+- from udp server (friends tracking) (experimental)
+
+
+Routing algorithm
+=================
+
+NavIt uses a Dijkstra algorithm for routing. The routing starts at the
+destination by assigning a value to each point directly connected to
+destination point. The value represents the estimated time needed to
+pass this distance.
+
+Now the point with the lowest value is choosen using the Fibonacci
+heap and a value is assigned to connected points whos are
+unevaluated or whos current value ist greater than the new one.
+
+The search is repeated until the origin is found.
+
+Once the origin is reached, all that needs to be done is to follow the
+points with the lowest values to the destination.
