DESCRIPTION
-----------
If no argument is provided, show available branches and mark current
branch with star. Otherwise, create a new branch of name <branchname>.
-
If a starting point is also specified, that will be where the branch is
created, otherwise it will be created at the current HEAD.
+With a `-d` or `-D` option, `<branchname>` will be deleted.

DESCRIPTION
-----------
-This simply creates an empty git repository - basically a `.git` directory

-and links `.git/HEAD` symbolically to `.git/refs/heads/master`.
+This command creates an empty git repository - basically a `.git` directory
+with subdirectories for `objects`, `refs/heads`, `refs/tags`, and
+templated files.
+An initial `HEAD` file that references the HEAD of the master branch
+is also created.
+
+If `--template=<template_directory>` is specified, `<template_directory>`
+is used as the source of the template files rather than the default.
+The template files include some directory structure, some suggested
+"exclude patterns", and copies of non-executing "hook" files. The
+suggested patterns and hook files are all modifiable and extensible.
If the `$GIT_DIR` environment variable is set then it specifies a path
to use instead of `./.git` for the base of the repository.

-
Running `git-init-db` in an existing repository is safe. It will not overwrite
things that are already there. The primary reason for rerunning `git-init-db`
is to pick up newly added templates.

-This hook is invoked by `git-receive-pack`, which is invoked

-three parameters, name of the ref being updated, old object name
-stored in the ref, and the new objectname to be stored in the

+This hook is invoked by `git-receive-pack` on the remote repository,
+which is happens when a `git push` is done on a local repository.
+Just before updating the ref on the remote repository, the update hook
+is invoked. It's exit status determins the success or failure of
+the ref update.
+
+The hook executes once for each ref to be updated, and takes
+three parameters:
+ - the name of the ref being updated,
+ - the old object name stored in the ref,
+ - and the new objectname to be stored in the ref.
+
+A zero exit from the update hook allows the ref to be updated.
+Exiting with a non-zero status prevents `git-receive-pack`
+from updating the ref.
+
+This hook can be used to prevent 'forced' update on certain refs by
making sure that the object name is a commit object that is a
descendant of the commit object named by the old object name.
+That is, to enforce a "fast forward only" policy.
+
+It could also be used to log the old..new status. However, it
+does not know the entire set of branches, so it would end up
+firing one e-mail per ref when used naively, though.
+
Another use suggested on the mailing list is to use this hook to
implement access control which is finer grained than the one
based on filesystem group.

post-update

+This hook is invoked by `git-receive-pack` on the remote repository,
+which is happens when a `git push` is done on a local repository.
+It executes on the remote repository once after all the refs have
+been updated.
+
+It takes a variable number of parameters, each of which is the
+name of ref that was actually updated.
This hook is meant primarily for notification, and cannot affect
the outcome of `git-receive-pack`.
+The post-update hook can tell what are the heads that were pushed,
+but it does not know what their original and updated values are,
+so it is a poor place to do log old..new.
+
The default post-update hook, when enabled, runs
`git-update-server-info` to keep the information used by dumb
-transport up-to-date.
+transports (eg, http) up-to-date. If you are publishing
+a git repository that is accessible via http, you should
+probably enable this hook.
The standard output of this hook is sent to /dev/null; if you
want to report something to the git-send-pack on the other end,
commands. A handful of sample hooks are installed when
`git init-db` is run, but all of them are disabled by
default. To enable, they need to be made executable.
