--builtin Allow plugins to load, but don't let them override builtin commands,
1633
they will still be allowed if they do not override a builtin.
1634
--no-plugins Don't load any plugins. This lets you get back to official source
1636
--profile Enable the hotspot profile before running the command.
1637
For backwards compatibility, this is also a non-master option.
1638
--version Spit out the version of bzr that is running and exit.
1639
This is also a non-master option.
1640
--help Run help and exit, also a non-master option (I think that should stay, though)
