TkCVS is a cross-platform, Tcl/Tk-based GUI for the CVS and Subversion configuration management systems. It displays the status of the files in the current working directory, and provides buttons and menus to execute CVS, Subversion, or RCS commands on the selected files. The Log Browser displays a branch diagram of the revision history. The Module Browser extends CVS with facilities for a user-friendly listing of modules in the repository. TkDiff is included for browsing and merging your changes.
The Helix Ribosome build system is a set of programs written in the Python programming language which provide a common interface to retrieving and building programs from source code stored in a CVS repository. The build system is made up of two basic subsystems. The first ("build") calculates the dependencies of a target, retrieves the source code, and runs commands to build that source code in the correct order. The second component ("Umake") is a cross-platform Makefile generator, which generates makefiles that work with MSVC, CodeWarrior, and typical Unix toolchains. Umake can be used independently from the build program.
The Distributed Concurrent Versioning System (DCVS) extends the well-known version control system CVS and the file distribution and synchronization program CVSup with functionality to distribute CVS repositories with local lines of development and handle synchronization of the distributed repositories automatically in the background. Development lines (branches) are owned by a repository server, repository servers efficiently update each other via CVSup, and CVS ensures correct server use on checkin and branch creation.
Aquamacs is a Mac-like version of the powerful Emacs text editor that runs as a standard OS X application. It features extensive customization that enables it to conform better with Apple's standard Human Interface Guidelines (HIG) than standard versions of the editor do. It provides a more Mac-like user experience than Carbon Emacs.
SmartCVS is a full-featured and still easy-to-use CVS client. It contains all needed tools out-of-the- box, so there is no need to install a file compare tool, CVS command line client, or SSH client. It is available in two versions: a free Foundation version and a commercial Professional version. The Professional version contains powerful features like a conflict solver, transaction view, tag browser (including tag/branch structure), and change report (multi-file compare).
CVS, GIT, and Mercurial as well as other well-known version control systems cannot version directories. In other words, you cannot add empty directories. A "workaround" for this issue is to use placeholder files that are placed into empty directories. These placeholder files can then be committed into the repository and will make sure that, upon checkout, the directory tree is entirely reconstructed. The problem with using placeholder files is that you need to create them, and need to delete them if they are not necessary anymore (because sub-directories or real files were added). With big source trees, managing these placeholder files can be cumbersome and error prone. MarkEmptyDirs can manage the creation/deletion of such placeholder files automatically. It creates placeholder files in all empty "leaf" directories. If later on new files or directories are put into such directories, the placeholder files are not necessary anymore, and are removed automatically.
