Bazaar (``bzr``) is a decentralized revision control system, designed to be
6
easy for developers and end users alike. Bazaar is part of the GNU project to
7
develop a complete free operating system.
9
To install Bazaar from source, follow the instructions in the INSTALL
10
file. Otherwise, you may want to check your distribution package manager
11
for ready-to-install packages, or http://bazaar-vcs.org/DistroDownloads.
13
To learn how to use Bazaar, check the documentation in the doc/ directory.
14
Once installed, you can also run 'bzr help'. An always up-to-date and more
15
complete set of documents can be found in the Bazaar website, at:
17
http://bazaar-vcs.org/Documentation
19
Bazaar is written in Python, and is sponsored by Canonical Limited, the
20
founders of Ubuntu and Launchpad. Bazaar is Free Software, and is released
21
under the GNU General Public License.
23
Bazaar was formerly known as Bazaar-NG. It's the successor to ``baz``, a fork
24
of GNU arch, but shares no code. (To upgrade from Baz, use the ``baz-import``
25
command in the bzrtools plugin.)
30
* Easy to use and intuitive.
32
Only five commands are needed to do all basic operations, and all
33
commands have documentation accessible via 'bzr help command'.
34
Bazaar's interface is also easy to learn for CVS and Subversion users.
36
* Robust and reliable.
38
Bazaar is developed under an extensive test suite. Branches can be
39
checked and verified for integrity at any time, and revisions can be
40
signed with PGP/GnuPG.
42
* Publish branches with HTTP.
44
Branches can be hosted on an HTTP server with no need for special
45
software on the server side. Branches can be uploaded by bzr itself
46
over SSH (SFTP), or with rsync.
48
* Adapts to multiple environments.
50
Bazaar runs on Linux and Windows, fully supports Unicode filenames,
51
and suits different development models, including centralized.
53
* Easily extended and customized.
55
A rich Python interface is provided for extending and embedding,
56
including a plugin interface. There are already many available plugins,
57
most of them registered at http://bazaar-vcs.org/PluginRegistry.
61
Changes will never be merged more than once, conflicts will be
62
minimized, and identical changes are dealt with well.
64
* Vibrant and active community.
66
Help with Bazaar is obtained easily, via the mailing list, or the IRC

* There is little locking or transaction control here; if you
14
interrupt it the tree may be arbitrarily broken. This will be

* Don't use this for critical data; at the very least keep separate
18
regular snapshots of your tree.
24
This is mostly developed on Linux (Ubuntu); it should work on Unix,
25
Windows, or OS X with relatively little trouble.
27
The only dependency is Python, at least 2.3 and preferably 2.4. On
28
Windows, Python2.4 is required.
30
You may optionally install cElementTree to speed up some operations.
36
The best way to install bzr is to symlink the ``bzr`` command onto a
37
directory on your path. For example::
39
ln -s ~/work/bzr/bzr ~/bin/bzr
41
If you use a symlink for this, Python will be able to automatically
42
find the bzr libraries. Otherwise you must ensure they are listed on
45
After installing, please run the test suite to identify any problems
50
If you use the setup.py script then bzr will be installed into the
51
specified path. In this case you must install ElementTree or
52
cElementTree separately.
