**WARNING: THIS IS AN UNSTABLE DEVELOPMENT VERSION**

Current limitation include:
27
28
* Metadata format is not stable yet -- you may need to
29
discard history in the future.
30
31
* No handling of subdirectories, symlinks or any non-text files.
32
33
* Insufficient error handling.
34
35
* Many commands unimplemented or partially implemented.
36
37
* Space-inefficient storage.
38
39
* No merge operators yet.

And are generally applied before plugins are loaded.
1641
1642
The current list are:
1643
--builtin Allow plugins to load, but don't let them override builtin commands,
1644
they will still be allowed if they do not override a builtin.
1645
--no-plugins Don't load any plugins. This lets you get back to official source
1646
behavior.
1647
--profile Enable the hotspot profile before running the command.
1648
For backwards compatibility, this is also a non-master option.
1649
--version Spit out the version of bzr that is running and exit.
1650
This is also a non-master option.
1651
--help Run help and exit, also a non-master option (I think that should stay, though)
