l.s.s.b.LaunchpadScriptFailure(Exception) : class documentation

Something bad happened and the script is going away.

When you raise LaunchpadScriptFailure inside your main() method, we do two things:

• log an error with the stringified exception
• sys.exit(1)

Releasing the lock happens as a side-effect of the exit.

Note that the sys.exit return value of 1 is defined as LaunchpadScriptFailure.exit_status. If you want a different value subclass LaunchpadScriptFailure and redefine it.
