devel/gitolite2 2.3.1 MidnightBSD

Gitolite is an access control layer on top of git, which allows access control down to the branch level, including specifying who can and cannot rewind a given branch.

Gitolite lets you use a single user on a server to host many git repositories and provide access to many developers, without having to give them real userids on or shell access to the server. Authentication is most commonly done using sshd, but you can also use httpd if you prefer.

Gitolite can restrict who can read from (clone/fetch) or write to (push) a repository. It can also restrict who can push to what branch or tag, which is very important in a corporate environment.
