The FILTR (File Inventory for Loading, Transfer, and Recovery) automates CVS functions for personal use, allowing a user to maintain a watch on any directory, mirroring it in an intermediate working directory and taking care of all import, add, delete, and update calls to the CVS repository. No changes or additions are made to the directory under watch. The user can revert a watched directory to any previous saved state with a button click, or call up one or several past versions of a file. Groups can also make use of the same repository for file sharing.
XOTclIDE is an integrated (interactive) development environment for the Tcl and XOTcl language, a highly flexible object-oriented extension of Tcl. It provides a Smalltalk-like programming environment similar to Squick. It allows graphical introspection and editing of a running system (based on Tcl's and XOTcl's introspection facilities). The system state can be saved in the form of Tcl packages. It can optionally use a version control system based on a relational database (MySQL, PostgreSQL, ODBC, or SQLite). All system changes are saved to the database on the fly. It provides browsers for viewing and editing xotcl classes and objects. It also contains syntax highlighting and a static code checker for TCL and xotcl. It contains many developer plugins.
Git is a "directory content manager" that was designed to handle massive projects such as the Linux kernel with speed and efficiency. It falls in the category of distributed source code management tools and is similar to GNU Arch, Monotone, and BitKeeper. Every Git working directory is a fully-fledged repository with full revision tracking capabilities and is not dependent on network access to a central server.
