Change the user-facing "git submodule--helper" commands so that they'll report their name as being "git submodule". To a user these commands are internal implementation details, and it doesn't make sense to emit usage about an internal helper when "git submodule" is invoked with invalid options. Before this we'd emit e.g.: $ git submodule absorbgitdirs --blah error: unknown option `blah' usage: git submodule--helper absorbgitdirs [<options>] [<path>...] [...] And: $ git submodule set-url -- -- usage: git submodule--helper set-url [--quiet] <path> <newurl> [...] Now we'll start with "usage: git submodule [...]" in both of those cases. This change does not alter the "list", "name", "clone", "config" and "create-branch" commands, those are internal-only (as an aside; their usage info should probably invoke BUG(...)). This only changes the user-facing commands. The "status", "deinit" and "update" commands are not included in this change, because their usage information already used "submodule" rather than "submodule--helper". I don't think it's currently possible to emit some of this usage information in practice, as git-submodule.sh will catch unknown options, and e.g. it doesn't seem to be possible to get "add" to emit its usage information from "submodule--helper". Though that change may be superfluous now, it's also harmless, and will allow us to eventually dispatch further into "git submodule--helper" from git-submodule.sh, while emitting the correct usage output.

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
