blame outputs an annotated revision from each RCS file. An annotated RCS file describes the revision and date in which each line was added to the file, and the author of each line.

CGit is an attempt to create a fast web interface for the Git SCM, using a built-in cache to decrease server I/O pressure.

Myrepos provides the mr command, which maps an operation (e.g., fetching updates) over a collection of version control repositories. It supports a large number of version control systems: Git, Subversion, Mercurial, Bazaar, Darcs, CVS, Fossil, and Veracity.

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.

Mercurial is a free, distributed source control management tool. It efficiently handles projects of any size and offers an easy and intuitive interface.

git open opens the repository's website from the command-line, guessing the URL pattern from the origin remote.

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

Neon is an HTTP and WebDAV client library, with a C interface and the following features:

1. High-level wrappers for common HTTP and WebDAV operations (GET, MOVE, DELETE, etc.);

2. low-level interface to the HTTP request/response engine, allowing the use of arbitrary HTTP methods, headers, etc.;

3. authentication support including Basic and Digest support, along with GSSAPI-based Negotiate on Unix, and SSPI-based Negotiate/NTLM on Win32;

4. SSL/TLS support using OpenSSL or GnuTLS, exposing an abstraction layer for verifying server certificates, handling client certificates, and examining certificate properties, smartcard-based client certificates are also supported via a PKCS#11 wrapper interface;

5. abstract interface to parsing XML using libxml2 or expat, and wrappers for simplifying handling XML HTTP response bodies;

6. WebDAV metadata support, wrappers for PROPFIND and PROPPATCH to simplify property manipulation.

Git Large File Storage (LFS) replaces large files such as audio samples, videos, datasets, and graphics with text pointers inside Git, while storing the file contents on a remote server.

Pre-commit is a multi-language package manager for pre-commit hooks. You specify a list of hooks you want and pre-commit manages the installation and execution of any hook written in any language before every commit.

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.

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 pijul, a sound and fast distributed version control system based on a mathematical theory of asynchronous work.

git-remote-gcrypt is a Git remote helper to push and pull from repositories encrypted with GnuPG. It works with the standard Git transports, including repository hosting services like GitLab.

Remote helper programs are invoked by Git to handle network transport. This helper handles gcrypt: URLs that access a remote repository encrypted with GPG, using our custom format.

Supported locations are local, rsync:// and sftp://, where the repository is stored as a set of files, or instead any Git URL where gcrypt will store the same representation in a Git repository, bridged over arbitrary Git transport.

The aim is to provide confidential, authenticated Git storage and collaboration using typical untrusted file hosts or services.

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.

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.

This hook sends emails describing changes introduced by pushes to a Git repository. For each reference that was changed, it emits one ReferenceChange email summarizing how the reference was changed, followed by one Revision email for each new commit that was introduced by the reference change.

This script is designed to be used as a post-receive hook in a Git repository

Git is a free distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

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.

git-credential-oauth is a Git credential helper that securely authenticates to GitHub, GitLab, BitBucket, Gerrit, Gitea, and Forgejo using OAuth. The first time you authenticate, the helper opens a browser window to the host. Subsequent authentication within storage lifetime is non-interactive.

CVS is a version control system, an important component of Source Configuration Management (SCM). Using it, you can record the history of sources files, and documents. It fills a similar role to the free software RCS, PRCS, and Aegis packages.

This program analyzes a collection of RCS files in a CVS repository (or outside of one) and, when possible, emits an equivalent history in the form of a fast-import stream. Not all possible histories can be rendered this way; the program tries to emit useful warnings when it can't.

The program can also produce a visualization of the resulting commit directed acyclic graph (DAG) in the input format of Graphviz. The package also includes cvssync, a tool for mirroring masters from remote CVS hosts.

diff-so-fancy strives to make your diffs human readable instead of machine readable. This helps improve code quality and helps you spot defects faster.

FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video. It includes the libavcodec audio/video codec library.
