Hgfs is a read-only filesystem interface to Mercurial repositories. The interface gives access to the commit message, manifest, and files of each revision, and to .tgz's of each revision (the .tgz's are generated as they are read). The filesystem is a front-end for the Mercurial library that comes with it. All code is written in Limbo, for Inferno.
Git# is a C# implementation of the Git version control system for the .NET platform. It is meant to be fully compatible to the original Git implementation in C for Linux. It can be used as a stand-alone command line application (potentially replacing msysGit on Windows) or as a library for applications such as GUI frontends or plugins for IDEs.
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.
pepper is a commandline tool for retrieving statistics and generating reports from source code repositories.
