These are things like bzr --no-plugins, etc.
1671
There are now 2 types of option flags. Ones that come *before* the command,
1672
and ones that come *after* the command.
1673
Ones coming *before* the command are applied against all possible commands.
1674
And are generally applied before plugins are loaded.
1676
The current list are:
1677
--builtin Allow plugins to load, but don't let them override builtin commands,
1678
they will still be allowed if they do not override a builtin.
1679
--no-plugins Don't load any plugins. This lets you get back to official source
1681
--profile Enable the hotspot profile before running the command.
1682
For backwards compatibility, this is also a non-master option.
1683
--version Spit out the version of bzr that is running and exit.
1684
This is also a non-master option.
1685
--help Run help and exit, also a non-master option (I think that should stay, though)
