AccuRev is a fast, powerful, and easy-to-use Software Configuration Management (SCM) tool with integrated issue tracking based on "Streams" that more efficiently manages complex parallel and global development. Streams are a combination and superset of branches and labels that are first class objects instead of being file-by-file attributes. AccuRev records all merges and patches, so you never have to re-merge the same code. It supports file and directory renaming and merging, follows a client/server model, and is transaction-based. It includes an integrated graphical 3-way diff and merge tool. AccuRev provides an Open API (and SDK) to integrate with any third-party development tool (IBM/Rational ClearQuest, Serena TeamTrack, and more out of the box). It also integrates with Eclipse, the MS SCC API (MS Visual Studio), Sun Java Studio, any diff/merge tool with a command line interface, and more.
Aegis is a transaction-based software configuration management system. It provides a framework within which a team of developers may work on many changes to a program independently, and Aegis coordinates integrating these changes back into the master source of the program, with as little disruption as possible. Aegis supports geographically distributed development.
changetrack is a program to monitor changes to files. If files are modified one day, and the machine starts working incorrectly some days later, changetrack can provide information on which files were modified, and help locate the problem. Changetrack will also allow recovery of the files from any stage.
jCVS is a Java based CVS Client. CVS is a source code control system based on RCS and extended to handle complete projects as a whole, rather than individual files. The primary benefit of CVS is that it provides a server/client protocol which allows clients such as jCVS to be written. JCVS allows any Java 1.1 capable machine to be a CVS client, providing for a totally distributed source code management system.
Jeremi is groupware software for realtime document sharing. It supports distributed work on different documents or files by different people or project groups. It offers an always-up-to-date view of the project and its files and coordinates the dependency of the actual file status and access to those files. Jeremi is written entirely in Java.
Katie is a revision control system, somewhat like a cross between CVS and NFS, that was inspired by Rational ClearCase. The three most interesting features are that the repository is mounted as a filesystem (rather than being copied to a local workspace), that all versions of all files (even deleted ones) are accessible through this filesystem (so the "katie diff" command is a convenience rather than a necessity like "cvs diff"), and that directories are versioned (just like files are). It is functional enough to be self-hosting, but there is much work still to go before it will be a generally useful tool. Features that are implemented already include VOBs, elements, branches, dynamic views, view-extended pathnames, config specs (including auto-make-branch rules), labels, hard links, and symbolic links.
