The Revision Control System (RCS) manages multiple revisions of files. RCS automates the storing, retrieval, logging, identification, and merging of revisions. RCS is useful for text that is revised frequently, for example programs, documentation, graphics, papers, and form letters.
SnapSource is a utility written in Perl to automatically and periodically take a snapshot (incremental backup) of your source code and display the modifications in a 2-column (original and modified) format similar to that of cervisia. Changes, additions, and deletions are displayed in different colors, customizable per user preference. It is not another CVS, and it is not a front-end to CVS, but it is supposed to be used in between CVS commits.
SOS is a design data management product built for hardware engineers. It allows version control for both binary files (eg. Schematic, Layout, Synthesis etc) and ASCII files (eg. VHDL, Verilog, C etc.) Furthermore, SOS provides design engineers to predictably create and re-create releases during tape-out. In addition to version control and release management, SOS has multiple features that enhance team collaboration and design productivity.
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.
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.
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.
