Cervisia is a KDE graphical frontend for the CVS client. It features checking out a module from a repository, updating or retrieving the status of a working directory or single files, common operations like add, remove and commit, diff against the repository and between different revisions, annotated view of a file, view of the log messages in tree and list form as well as resolving of conflicts in a file.
CVS is a version control system, which allows you to keep old versions of files (usually source code), keep a log of who, when, and why changes occurred, etc., like RCS or SCCS. Unlike the simpler systems, CVS does not just operate on one file at a time or one directory at a time, but operates on hierarchical collections of directories consisting of version controlled files. CVS helps to manage releases and to control the concurrent editing of source files among multiple authors. CVS allows triggers to enable/log/control various operations and works well over a wide area network.
cvs2html is a Perl program to transform the output of 'cvs log' to HTML. The HTML output will show the revision log history, differences between versions and enable a flexible configuration of the amount of information the user likes to see from the CVS repository. cvs2html can be used for any type of cvs archive.
cvsd is a wrapper program for CVS in pserver mode. It will run 'cvs pserver' under a special uid/gid in a chroot jail. cvsd is run as a daemon and is controlled through a configuration file. It is easy to configure and provides tools for setting up a rootjail and managing repositories.
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.
