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.
cvsq (CVS queued) is a tool that enables developers with a dial-up connection to work comfortably with CVS. It accepts same arguments as CVS but instead of directly processing them, cvsq stores all requests in a queue and handles them later. This way, you can mark several files for commit and upload them when you're connected to the Net.
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.
CVSup is a software package for transferring and updating collections of files across a network. It consists of a server called cvsupd and a client called cvsup. CVSup is faster (often by an order of magnitude) and more flexible than traditional network packages such as rdist and sup. In addition, CVSup has special knowledge of RCS files (as used by CVS). Software projects using CVSup to distribute their CVS repositories include FreeBSD, KDE, and (shortly) Postgres.
cvsweb is a visual (WWW) interface for exploring a CVS repository. Its enhancements include recognition and display of popular MIME-types, visual, color-coded, side-by-side diffs of changes, and the ability sort the file display and to hide old files from view. cvsweb requires the server to have CVS and a CVS repository worth exploring.
