**WARNING: THIS IS AN UNSTABLE DEVELOPMENT VERSION**
23
Current limitation include:
25
* Metadata format is not stable yet -- you may need to
26
discard history in the future.
28
* Insufficient error handling.
30
* Many commands unimplemented or partially implemented.
32
* Space-inefficient storage.
34
* No merge operators yet.
36
Interesting commands::
41
Show software version/licence/non-warranty.
43
Start versioning the current directory
47
Show revision history.
49
Show changes from last revision to working copy.
50
bzr commit -m 'MESSAGE'
51
Store current state as new revision.
52
bzr export REVNO DESTINATION
53
Export the branch state at a previous version.
55
Show summary of pending changes.
57
Make a file not versioned.

Show statistics about this branch.
