There are now 2 types of option flags. Ones that come *before* the command,
1522
and ones that come *after* the command.
1523
Ones coming *before* the command are applied against all possible commands.
1524
And are generally applied before plugins are loaded.
1525
1526
The current list are:
1527
--builtin Allow plugins to load, but don't let them override builtin commands,
1528
they will still be allowed if they do not override a builtin.
1529
--no-plugins Don't load any plugins. This lets you get back to official source
1530
behavior.
1531
--profile Enable the hotspot profile before running the command.
1532
For backwards compatibility, this is also a non-master option.
1533
--version Spit out the version of bzr that is running and exit.
1534
This is also a non-master option.
1535
--help Run help and exit, also a non-master option (I think that should stay, though)
