# Description

Adds a tutorial explaining how to use the AppLauncher class and
corresponding script. Also slightly modifies AppLauncher by removing -1
from the list of argument choices for --livestream and --ros, as these
are options used internally and which should never be entered by a user.

Fixes #229 (partially)
