| // NOTE: This code is currently below version 1.0, and therefore is considered |
| // to be lacking in some functionality or documentation, or may not be fully |
| // tested. Nonetheless, you can expect most functions to work. |

| /// \par Overview |
| /// This library parses and decodes the standard NMEA data stream from a |
| /// GPS and stores the position, velocity, and time solutions in the gps.c |
