There are now 2 types of option flags. Ones that come *before* the command,
1523
and ones that come *after* the command.
1524
Ones coming *before* the command are applied against all possible commands.
1525
And are generally applied before plugins are loaded.

The current list are:
1528
--builtin Allow plugins to load, but don't let them override builtin commands,
1529
they will still be allowed if they do not override a builtin.
1530
--no-plugins Don't load any plugins. This lets you get back to official source
1531
behavior.
1532
--profile Enable the hotspot profile before running the command.
1533
For backwards compatibility, this is also a non-master option.
1534
--version Spit out the version of bzr that is running and exit.
1535
This is also a non-master option.
1536
--help Run help and exit, also a non-master option (I think that should stay, though)
