"""Bazaar-NG -- a free distributed version-control tool

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

Current limitation include:

* Metadata format is not stable yet -- you may need to
  discard history in the future.

* Insufficient error handling.

* Many commands unimplemented or partially implemented.

* Space-inefficient storage.

* No merge operators yet.

Interesting commands::

  bzr help [COMMAND]
       Show help screen
  bzr version
       Show software version/licence/non-warranty.
  bzr init
       Start versioning the current directory
  bzr add FILE...
       Make files versioned.
  bzr log
       Show revision history.
  bzr diff
       Show changes from last revision to working copy.
  bzr commit -m 'MESSAGE'
       Store current state as new revision.
  bzr export REVNO DESTINATION
       Export the branch state at a previous version.
  bzr status
       Show summary of pending changes.
  bzr remove FILE...
       Make a file not versioned.
  bzr info
       Show statistics about this branch.
