I wrote the code, so I know what it's saying. It's showing you the config.ini variable it's looking for a match for, whether or not we were already inside a [gpsapp] section before the chunk we're looking at now, and the chunk we're looking at, which is either the whole file or up to 512 bytes if it's larger than that. The "inside" test is necessary as gpsapp will parse consecutive chunks and remember if it was already inside the [gpsapp] section when it gets into the next section. It will also rewind enough before moving to the next chunk to ensure the [gpsapp] tag wasn't broken into 2 pieces over the chunk boundary.

This new binary will tell you routedir instead of telling you it's "waiting for gps input" in the popup.
