fast, scalable, distributed revision control system (git-daemon service)

 Git is popular version control system designed to handle very large
 projects with speed and efficiency; it is used for many high profile
 open source projects, most notably the Linux kernel.
 .
 Git falls in the category of distributed source code management tools.
 Every Git working directory is a full-fledged repository with full
 revision tracking capabilities, not dependent on network access or a
 central server.
 .
 git-daemon, as provided by the git package, is a simple server for git
 repositories, ideally suited for read-only updates, i.e. pulling from git
 repositories through the network. This package provides a sysvinit service
 for running git-daemon permanently. Unlike git-daemon-run, this
 package provides the usual sysvinit service management commands
 ("service git-daemon start/stop") for git-daemon.
