+//  Program: NMEA_isr.ino
+//
+//  Prerequisites:
+//     1) NMEA.ino works with your device
+//
+//  Description:  This minimal program parses the GPS data during the 
+//     RX character interrupt.  The ISR passes the character to
+//     the GPS object for parsing.  The GPS object will add gps_fix 
+//     structures to a buffer that can be later read() by loop().
