Aegis Aegis is a transaction-based software management system. It provides a framework within which developers work on changes independently, and coordinates integrating those changes back into the master source code. The program supports geographically distributed development. Aegis supports distributed and multiple repositories, change sets, multiple lines of development, multiple simultaneous active branches, and branching to any depth. It enforces a development process which requires that change sets "work" (they must build successfuly and optionally include and pass tests) before being integrated into the project baseline. It also ensures that code reviews have been performed. The program also supports long transactions, which allows appropriately created changes to be treated as if they were projects and therefore to have changes made to them. This allows a hierarchy of changes within changes, to any depth. Each project is a separate repository, with separately configurable policies.

ArchZoom ArchZoom is a Web-based browser for the GNU Arch revision control system with minimal requirements and decent configurability. It provides easy-to-use navigation from managed archives to complete revision trees and features multiple views, like expanded changeset information with colored diffs inline.

Authz-tools 'authz-tools' is a set of tools to manipulate authz files (as used by mod_authz_svn). It currently contains two utilities:

authz-tool -- extracts and modifies information in a
authz file from command line

authz-admin -- a cgi when you have numerous repositories served with
help of SVNParentPath directive (see mod_dav_svn
module documentation)

Bazaar Bazaar (``bzr``) is a version control system that helps you track project history over time and to collaborate easily with others. Whether you're a single developer, a co-located team or a community of developers scattered across the world, Bazaar scales and adapts to meet your needs. Part of the GNU Project, Bazaar is free software sponsored by Canonical. For a closer look, see ten reasons to switch to Bazaar

Blame 'Blame' displays the last modification for each line in an RCS file. It is the RCS equivalent of CVS's "annotate" command. An annotated RCS file describes the revision and date in which each line was added to the file, and the author of each line.

Bonsai 'Bonsai' lets you perform queries on the contents of a CVS archive. You can get a list of checkins, and see what checkins have been made by a given person, on a given branch, or in given time. It also includes tools for sxamining checkin logs and comments, doing diffs between various versions of a file, and finding out who is responsible for changing a particular line of code ("cvsblame"). It is built to run against CVS using Perl, MySQL, and your favorite webserver to display checkin history, log information, diffs, and other assorted pieces of information in easy to parse HTML.

BzrPublish BzrPublish is a simple tool that makes it easy to create releases from a project under bzr control. Commands are provided for creating tarballs, publishing beta and official releases, and for publishing development logs and repositories over SSH.

CIA 'CIA' is a system for tracking free and open source projects in real- time. It features announcement of commits via IRC, a Web interface, XML-RPC, and RSS feeds. The codebase is easy to extend to support message types other than commits, and new ways to deliver them.

CVS Version control system and important component of Source Configuration Management (SCM). Lets you record the history of source files and documents. It's similar to the free software RCS, PRCS, and Aegis programs, but has the following significant advantages over RCS:

• runs user scripts to log operations or enforce site-specific policies
• lets separatedevelopers operate as a team
• vendor branches keep versions separate, but also merge them if needed
• unreserved checkouts let developers work simultaneously on the same files
• flexible modules database maps names to the components of a larger database
• runs on most Unix variants; clients for Windows 95/NT, OS/2, and VMS available

CVSGraph CvsGraph is a utility to make a graphical representation of all revisions and branches of a file in a CVS/RCS repository.
