And are generally applied before plugins are loaded.
1636
The current list are:
1637
--builtin Allow plugins to load, but don't let them override builtin commands,
1638
they will still be allowed if they do not override a builtin.
1639
--no-plugins Don't load any plugins. This lets you get back to official source
1641
--profile Enable the hotspot profile before running the command.
1642
For backwards compatibility, this is also a non-master option.
1643
--version Spit out the version of bzr that is running and exit.
1644
This is also a non-master option.
1645
--help Run help and exit, also a non-master option (I think that should stay, though)
