Fossil is a distributed software configuration management/version control system built with reliability and ease of use on mind. It comes with integrated bug tracking and a wiki. It is distributed as a single static binary for easy installation and the ability to run in a chrooted environment. Other highlights include a Web interface, autosync, simple networking, and CGI support.
dumbsvnreview is a very simple frontend for performing code reviews with SVN. The idea is that you set it up with your repositories and your favorite graphical diff tool and specify the last revision of the last code review. It will then list every change since the last review through a Web interface.
Running sccs2rcs in a directory with an SCCS subdirectory will convert all the SCCS files to corresponding RCS master files in a new RCS directory; the SCCS data itself is accessed read-only. It will complain and terminate if any of the SCCS files are checked out, or if the RCS directory already exists and is non-empty. If the directory contains snapshot auxiliary data produced by Emacs VC mode for tagging, that will be used too.
AVS is a source configuration management software that embedds a bug tracking feature. It is based on a common file "check-out / check-in" procedure, which eases early conflict detection. A file can have parallel versions. A proprietary 3-way merge tool is bundled to help merging. AVS uses a development task concept, which allows grouping checked-out files for the same purpose. Users can then work on several tasks at once without confusing files. Each development task is natively linked to a change request, which can be linked to several tasks. The build manager then relies on a change request selection within a set, while still being able to unselect some tasks if needed. A user management feature, with groups and access rights, is provided to restrict access to users upon their profile.
