Bazaar

From RBOSE

Bazaar (formerly Bazaar-NG, command line tool bzr) is a distributed revision control system sponsored by Canonical Ltd., designed to make it easier for anyone to contribute to free and open source software projects. It is written in the Python programming language, with packages for major GNU/Linux distributions, Mac OS X and MS Windows. Bazaar is free software and part of the GNU project.

Bazaar can be used by a single developer working on multiple branches of local content, or by teams collaborating across a network.

Features

Bazaar commands are quite similar to those found in CVS or Subversion, and a new project can be started and maintained without a remote repository server by invoking the bzr init command in a directory which a person wishes to version.^[1]

In contrast to purely distributed version control systems which don't use a central server, Bazaar supports working with or without a central server. It is possible to use both methods at the same time with the same project. The websites Launchpad and Sourceforge provide free hosting service for projects managed with Bazaar.

Bazaar has support for working with some other revision control systems.^[2] This allows users to branch from another system (such as Subversion^[3]), make local changes and commit them into a Bazaar branch, and then later merge them back into the other system. Read-only access is also available for Git^[4] and Mercurial.^[5]. Bazaar also allows for interoperation with many other systems (including CVS, Darcs, Git, Perforce, Mercurial) by allowing to import/export the history.^[6]

Bazaar supports files with names from the complete Unicode set. It also allows commit messages, committer names, etc. to be in Unicode.
