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.
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.
TIA is an ncurses-based console IDE for GCC, G++, Java, Perl, PHP, BASH, BUSH, HTML, and GNAT (Ada 95). It has integrated support for CVS, SVN, and ncurses compatible mice. Features include a ddd-style console debugger, automatic spelling correction, keyword hilighting, project statistics, automatic backups, and keyboard macros. The project window controls optimization and debug settings all in one place. TIA supports make, cook, and gnatmake project builders. For large projects, each user has a separate preference file.
ViewVC (formerly known as ViewCVS) is a Python/CGI-based system for viewing and interacting with Subversion and CVS repositories through your Web browser. It can browse directories, view changelogs, generate diffs, view arbitrary revisions, and display annotated ("blame") listings. It has full support for tags and branches, and contains a database-backed query system like Bonsai. It was initially based on the cvsweb work by Henner Zeller, but has been ported to Python and dramatically enhanced.
Chora is built upon the Horde Application Framework and provides a read-only browser interface to any number of version control repositories. Advanced features include a visual branch view of the repository's history, pretty-printed output, annotation, patchsets and basic statistics.
