+~NMEA~ is an acronym for National marine Electronics Association. The
+NMEA format described in this document follows the NMEA 0183
+standard. It is a newline-delimited streaming text format that encodes
+global positioning system (GPS) data such as WGS84 location, time and
+date information, satellite count, accuracy, and other
+information. Each line is an "NMEA sentence". Descriptions of various
+NMEA sentences can be found on [[http://aprs.gids.nl/nmea/][this]] webpage.
