+This option splits tracks at segment boundaries into multiple tracks. This
+is useful to restore the behaviour of GPSBabel versions up to 1.3.6 which
+didn't support track segment markers and automatically put each segment into
+a separate track.

+This option merges multiple tracks, inserting segment separators at
+track boundaries. It expects the tracks to already be in the right order for
+merging, i.e. it does not check timestamps and reorder track points so that
+their timestamps are monotonically increasing.
