These are things like bzr --no-plugins, etc.
1454
There are now 2 types of option flags. Ones that come *before* the command,
1455
and ones that come *after* the command.
1456
Ones coming *before* the command are applied against all possible commands.
1457
And are generally applied before plugins are loaded.
1459
The current list are:
1460
--builtin Allow plugins to load, but don't let them override builtin commands,
1461
they will still be allowed if they do not override a builtin.
1462
--no-plugins Don't load any plugins. This lets you get back to official source
1464
--profile Enable the hotspot profile before running the command.
1465
For backwards compatibility, this is also a non-master option.
1466
--version Spit out the version of bzr that is running and exit.
1467
This is also a non-master option.
1468
--help Run help and exit, also a non-master option (I think that should stay, though)
