**WARNING: THIS IS AN UNSTABLE DEVELOPMENT VERSION**
23
* Metadata format is not stable yet -- you may need to
24
discard history in the future.
26
* Many commands unimplemented or partially implemented.
28
* Space-inefficient storage.
30
* No merge operators yet.
33
To make a branch, use 'bzr init' in an existing directory, then 'bzr
34
add' to make files versioned. 'bzr add .' will recursively add all
37
'bzr status' describes files that are unknown, ignored, or modified.
38
'bzr diff' shows the text changes to the tree or named files.
39
'bzr commit -m <MESSAGE>' commits all changes in that branch.
41
'bzr move' and 'bzr rename' allow you to rename files or directories.
42
'bzr remove' makes a file unversioned but keeps the working copy;
43
to delete that too simply delete the file.
45
'bzr log' shows a history of changes, and
46
'bzr info' gives summary statistical information.
47
'bzr check' validates all files are stored safely.
49
Files can be ignored by giving a path or a glob in .bzrignore at the
50
top of the tree. Use 'bzr ignored' to see what files are ignored and
51
why, and 'bzr unknowns' to see files that are neither versioned or
