ReadOSM is an open source library to extract valid data from within an
OpenStreetMap input file. Such OSM files come in two different formats:
 * files identified by the .osm suffix simply are plain XML files.
 * files identified by the .osm.pbf suffix does containt the same
   identical data, but adopting the Google's Protocol Buffer
   serialization format and thus requiring much less storage space.
