[This is still a draft, but I think I incorporated the suggestons from
the last attempt.]
Source Code Management with Git
Git, sometimes called "global information tracker", is a "directory
content manager". Git has been designed to handle absolutely massive
projects with speed and efficiency, and the release of the 2.6.12 and
(soon) the 2.6.13 version of the Linux kernel would indicate that it
does this task well.
Git falls into the category of distributed source code management tools,
similar to Arch or Darcs (or, in the commercial world, BitKeeper). Every Git
working directory is a full-fledged repository with full revision tracking
capabilities, not dependent on network access to a central server.
Git uses the SHA1 hash algorithm to provide a content-addressable pseudo
filesystem, complete with its own version of fsck.
o Speed of use, both for the project maintainer, and the end-users, is
a key development principle.
o The history is stored as a directed acyclic graph, making long-lived
branches and repeated merging simple.
o A collection of related projects are building on the core Git project,
either to provide an easier to use interface on top (StGit, Cogito, qgit,
gitk, gitweb), or to take some of the underlying concepts and reimplement
them directly into another system (Arch 2.0, Darcs-git).
o Two, interchangeable, on-disk formats are used:
o An efficient, packed format that saves spaced and network
bandwidth.
o An unpacked format, optimized for fast writes and incremental
work.

Source tarballs and RPMs at:

Deb packages at:

Or via Git itself:
git clone http://www.kernel.org/pub/scm/git/git.git/
git clone rsync://rsync.kernel.org/pub/scm/git/git.git/
(rsync is generally faster for an initial pull)
Git distributions contain a tutorial in the Documentation subdirectory.
Additionally, the Kernel-Hacker's Git Tutorial at
http://linux.yyz.us/git-howto.html may be useful. (Thanks to Jeff Garzik for
that document)

Mailing list archives are available at http://marc.theaimsgroup.com/?l=git
Git results from the inspiration and frustration of Linus Torvalds, and
the enthusiastic help of over 300 participants on the development
mailing list.[1] It is maintained by Junio C Hamano <[EMAIL PROTECTED]>.
