+BRouter is a highly flexible router specializing in bike routing. Osm2pgsql is
+used to read OSM data into a database for extensive preprocessing to add useful
+information as "pseudo tags" to the routing graph. This way routes through
+quiet forest and along scenic rivers can be preferred over dangerous
+intersections and busy city streets.
