Subject: [PATCH] Don't implement the usage message of tg depend more than once
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The implmentation of "tg depend" had the usage message in two places.
Fixed by creating a usage function, so that there is a single place
to edit if the usage changes.
