    longDescription = ''
      gpsd is a service daemon that monitors one or more GPSes or AIS
      receivers attached to a host computer through serial or USB ports,
      making all data on the location/course/velocity of the sensors
      available to be queried on TCP port 2947 of the host computer. With
      gpsd, multiple location-aware client applications (such as navigational
      and wardriving software) can share access to receivers without
      contention or loss of data. Also, gpsd responds to queries with a
      format that is substantially easier to parse than the NMEA 0183 emitted
      by most GPSes. The gpsd distribution includes a linkable C service
      library, a C++ wrapper class, and a Python module that developers of
      gpsd-aware applications can use to encapsulate all communication with
      gpsd. Third-party client bindings for Java and Perl also exist.

      Besides gpsd itself, the project provides auxiliary tools for
      diagnostic monitoring and profiling of receivers and feeding
      location-aware applications GPS/AIS logs for diagnostic purposes.
