vcsh version-controls configuration files in several Git repositories, all in one single directory. They all maintain their working trees without clobbering each other or interfering otherwise. By default, all Git repositories maintained via vcsh store the actual files in $HOME, though this can be overridden.

Breezy (brz) is a decentralized revision control system. By default, Breezy provides support for both the Bazaar and Git file formats. Breezy is backwards compatible with Bazaar's disk format and protocols. One of the key differences with Bazaar is that Breezy runs on Python 3.3 and later, rather than on Python 2.

git-cal is a script to view commits calendar similar to GitHub contributions calendar.

GNU Arch, aka. tla, was one of the first free distributed version-control systems (DVCS). It saw its last release in 2006. This package is provided for users who need to recover tla repositories and for historians.

GitDB allows you to access bare Git repositories for reading and writing. It aims at allowing full access to loose objects as well as packs with performance and scalability in mind. It operates exclusively on streams, allowing to handle large objects with a small memory footprint.

Aegis is a project change supervisor, and performs some of the Software Configuration Management needed in a CASE environment. Aegis provides a framework within which a team of developers may work on many changes to a program independently, and Aegis coordinates integrating these changes back into the master source of the program, with as little disruption as possible. Resolution of contention for source files, a major headache for any project with more than one developer, is one of Aegis's major functions.

RCS is the original Revision Control System. It works on a file-by-file basis, in contrast to subsequent version control systems such as CVS, Subversion, and Git. This can make it suitable for system administration files, for example, which are often inherently local to one machine.

This package reads and writes loose and packed (objects found in git packfiles) Git objects. It uses the pack package to search pack index files and locate the corresponding delta-base chain in the appropriate pack file. If gitobj can't find a loose object with the appropriate SHA-1, it will search the repository's packfile(s) instead. If it finds an object in a packfile, it will reconstruct the object along its delta-base chain and return it.

GNU CSSC provides a replacement for the legacy Unix source code control system SCCS. This allows old code still under that system to be accessed and migrated on modern systems.

The vc-dwim package contains two tools, "vc-dwim" and "vc-chlog". vc-dwim is a tool that simplifies the task of maintaining a ChangeLog and using version control at the same time, for example by printing a reminder when a file change has been described in the ChangeLog but the file has not been added to the VC. vc-chlog scans changed files and generates standards-compliant ChangeLog entries based on the changes that it detects.

This package a interactive tool to interact with git branches using StGit.

The b4 command is designed to make it easier to participate in patch-based workflows for projects that have public-inbox archives.

Features include:

• downloading a thread's mbox given a message ID

• processing an mbox so that is ready to be fed to git-am

• creating templated replies for processed patches and pull requests

• submitting cryptographic attestation for patches.

ghq provides a way to organize remote repository clones, like go get does. When you clone a remote repository by ghq get, ghq makes a directory under a specific root directory (by default ~/ghq) using the remote repository URL's host and path.

This package provides a way of visualizing a heat map of a git repo.

Gitlint is a Git commit message linter written in Python: it checks your commit messages for style.

fnc uses ncurses and libfossil to create a fossil user interface in the terminal. It can view local changes at the hunk level to prepare atomic commits.

Tig is an ncurses text user interface for Git, primarily intended as a history browser. It can also stage hunks for commit, or colorize the output of the git command.

Fossil is a distributed source control management system which supports access and administration over HTTP CGI or via a built-in HTTP server. It has a built-in wiki, built-in file browsing, built-in tickets system, etc.

git filter-repo is a versatile tool for rewriting history, which roughly falls into the same space of tool like git filter-branch but with more capabilities. git filter-repo is now recommended by the Git project instead of git filter-branch.

StGit uses a patch stack workflow. Each individual patch focuses on a single concern, while a stack of patches forms a series of commits. Patches are stored as normal git commits, allowing easy merging of StGit patches into other repositories using standard Git.

Features include:

• Import and export patches from Git with stg commit and stg uncommit

• Create new patches and add them to the stack with stg new

• Update a patch from the working tree with stg refresh and stg edit

• See information about the stack or patch with stg series and stg show

• Export and send a series of patches by email using stg email

This package provides a Mercurial extension for signing the changeset hash of commits. The signure is embedded directly in the changeset itself; there won't be any extra commits. Either GnuPG or OpenSSL can be used for signing.

The git-extras package provides a collection of additional git commands for repository metrics and summarization, commit and log editing, developer workflow, and project and release management.

git-spice (gs) is a command line tool for stacking Git branches, a collection of branches expecting the trunk has a base branch. It manages and navigates stacks of branches, conveniently modifies and rebases them also provides an integration with GitHub and GitLab.

Libgit2 is a portable, pure C implementation of the Git core methods provided as a re-entrant linkable library with a solid API, allowing you to write native speed custom Git applications in any language with bindings.
