CVSsuck is a mirroring tool for CVS repositories. Unlike other tools such as CVSup or rsync, it uses cvs command to access the repository. So, it works well with remote repositories without a special server or shell account. However, it is inefficient because the CVS client/server protocol is not designed for mirroring.
p4delta works with a project that is in the Perforce configuration management system. It lists the local files that have been added, changed, or deleted. Content differences are summarized, i.e., the number of lines of code that have been added, changed, and deleted. It can also add, edit, and remove the appropriate files to/from Perforce.
FastCST (Fast Change Set Tool) is an experiment in creating a secure revision control system that uses digital signatures and other cryptographic means to verify the identity of submitters. It attempts to strike a balance between security, collaboration, and control, such that everyone can participate safely, no one individual or organization can control others, and collaborators are free to share as they need. It is simple, well tested, and well documented.
rconftool is a reimplementation of Sam Varshavchik's sysconftool in Ruby. Its purpose is to keep configuration files "fresh" when upgrading an application from one version to another, ensuring that all necessary settings are present and that obsolete ones are removed. To use it, application writers need to distribute their config files marked up with some simple metadata in comments, and arrange for the "make install" or "make install-configure" target to invoke rconftool. rconftool can be called as a library function or from the command line. It can also install groups of files recursively from one directory tree into another.
svndelta helps manage a Subversion project, identifying the local files that have been added, changed, or deleted. The relevant files can be automatically added to and removed from Subversion. A list of files is produced, with a summary of content differences, i.e. the number of lines of code that have been added, changed, and deleted.
