Ævar Arnfjörð Bjarmason b7ba8587c3 git-compat-util.h: clarify GCC v.s. C99-specific in comment Change a comment added in `e208f9cc75` (make error()'s constant return value more visible, 2012-12-15). It's not correct that this is GCC-ism anymore, it's code that uses standard C99 features. The comment being changed here pre-dates the HAVE_VARIADIC_MACROS define, which we got in `e05bed960d` (trace: add 'file:line' to all trace output, 2014-07-12). The original implementation of an error() macro) in `e208f9cc75` used a GCC-ism with the paste operator (see the commit message for mention of it), but that was dropped later by `9798f7e5f9` (Use __VA_ARGS__ for all of error's arguments, 2013-02-08), giving us the C99-portable version we have now. While we could remove the __GNUC__ define here, it might cause issues for other compilers or static analysis systems, so let's not. See `87fe5df365` (inline constant return from error() function, 2014-05-06) for one such issue. See also `e05bed960d` (trace: add 'file:line' to all trace output, 2014-07-12) for another comment about GNUC's handling of __VA_ARGS__.

Git - fast, scalable, distributed revision control system

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.

See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.

CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).

The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).

Those wishing to help with error message, usage and informational message string translations (localization l10) should see po/README.md (a po file is a Portable Object file that holds the translations).

To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.

Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.

The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.

The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):

random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
"global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
"goddamn idiotic truckload of sh*t": when it breaks
