KLMNEA
KLMNEA is a beginning of Common Lisp NMEA protocol parser. For now predefined are $GPRMC, $GPGGA, $GPGSA and $GPGSV. You may do something useful by (re)defining PROCESS-NMEASSAGE method for a message, and then calling PROCESS-NMEA with a string you got from somewhere. More messages and utils will follow.
