/**
* This package contains components for accessing GPS systems
* using a serial port connection and the NMEA protocol. It relies
* on the RXTX serial port library. To use the functionality, it is
* therefore necessary, to download the rs232 serial port library
* from http://www.rxtx.org/ and to install it correctly. After that,
* rename <code>NmeaSerialPortReader.txt</code> to
* <code>NmeaSerialPortReader.java</code>.
*
* <p>Class <code>GpsLocator</code> is used to publish position
* informations. It receives NMEA messages via a <code>NmeaReader</code>.
* The message source can either be a serial port or a file. A
* reader factory exists, which hides implementation details. The
* serial port reader, which is provided as text file, initially scans
* all serial ports and selects the first which provides NEMEA messages.
* When connecting a second time, it uses the information of the last
* successful scan.
