**WARNING: THIS IS AN UNSTABLE DEVELOPMENT VERSION**
26
Current limitation include:
28
* Metadata format is not stable yet -- you may need to
29
discard history in the future.
31
* No handling of subdirectories, symlinks or any non-text files.
33
* Insufficient error handling.
35
* Many commands unimplemented or partially implemented.
37
* Space-inefficient storage.
39
* No merge operators yet.
41
Interesting commands::
44
Show summary help screen
46
Show software version/licence/non-warranty.
48
Start versioning the current directory
52
Show revision history.
54
Show changes from last revision to working copy.
55
bzr commit -m 'MESSAGE'
56
Store current state as new revision.
57
bzr export REVNO DESTINATION
58
Export the branch state at a previous version.
60
Show summary of pending changes.
62
Make a file not versioned.
65
# not currently working:

The SPEC parameters are working tree or revision specifiers. Working trees

Working tree examples: '.', '..', 'foo@', but NOT 'foo/@bar'

Revision examples: './@127', 'foo/@', '../@1'
