DESCRIPTION
-----------
-This command creates an empty git repository - basically a `.git` directory
-with subdirectories for `objects`, `refs/heads`, `refs/tags`, and
-template files.
-An initial `HEAD` file that references the HEAD of the master branch
-is also created.
-
-If the `$GIT_DIR` environment variable is set then it specifies a path
-to use instead of `./.git` for the base of the repository.
-
-If the object storage directory is specified via the `$GIT_OBJECT_DIRECTORY`
-environment variable then the sha1 directories are created underneath -
-otherwise the default `$GIT_DIR/objects` directory is used.
-
-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.
-
-Note that `git-init` is the same as `git-init-db`.

+
+Note that `git-init` is the same as `git-init-db`. The command
+was primarily meant to initialize the object database, but over
+time it has become responsible for setting up the other aspects
+of the repository, such as installing the default hooks and
+setting the configuration variables. The old name is retained
+because people are so used to it and many existing documents
+refer to it that way, and this will not change for some time to
+come.

SYNOPSIS

-'git-pack-refs' [--all] [--prune]
+'git-pack-refs' [--all] [--no-prune]
DESCRIPTION
-----------
This option causes branch tips to be packed as well. Useful for
a repository with many branches of historical interests.
-\--prune::
+\--no-prune::
+
+The command usually removes loose refs under `$GIT_DIR/refs`
+hierarchy after packing them. This option tells it not to.
-After packing the refs, remove loose refs under `$GIT_DIR/refs`
-hierarchy. This should probably become default.

+
+NAME
+----
+git-remote - manage set of tracked repositories
+
+
+SYNOPSIS
+--------
+[verse]
+'git-remote'
+'git-remote' add <name> <url>
+'git-remote' show <name>
+
+DESCRIPTION
+-----------
+
+Manage the set of repositories ("remotes") whose branches you track.
+
+With no arguments, shows a list of existing remotes.
+
+In the second form, adds a remote named <name> for the repository at
+<url>. The command `git fetch <name>` can then be used to create and
+update remote-tracking branches <name>/<branch>.
+
+In the third form, gives some information about the remote <name>.
+
+The remote configuration is achieved using the `remote.origin.url` and
+`remote.origin.fetch` configuration variables. (See
+gitlink:git-repo-config[1]).
+
+Examples
+--------
+
+Add a new remote, fetch, and check out a branch from it:
+
+------------
+$ git remote
+origin
+$ git branch -r
+origin/master
+$ git remote add linux-nfs git://linux-nfs.org/pub/nfs-2.6.git
+$ git remote
+linux-nfs
+origin
+$ git fetch
+* refs/remotes/linux-nfs/master: storing branch 'master' ...
+ commit: bf81b46
+$ git branch -r
+origin/master
+linux-nfs/master
+$ git checkout -b nfs linux-nfs/master

"git-svn-HEAD" instead of "remotes/git-svn" as the branch
for tracking the remote.
---no-ignore-externals::
-Only used with the 'fetch' and 'rebuild' command.
-
-This command has no effect when you are using the SVN::*
-libraries with git, svn:externals are always avoided.
-
-By default, git-svn passes --ignore-externals to svn to avoid
-fetching svn:external trees into git. Pass this flag to enable
-externals tracking directly via git.
-
-Versions of svn that do not support --ignore-externals are
-automatically detected and this flag will be automatically
-enabled for them.
-
-Otherwise, do not enable this flag unless you know what you're
-doing.

------------------------------------------------
-Advanced Example: Tracking a Reorganized Repository
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Note: this example is now obsolete if you have SVN::* libraries
-installed. Simply use --follow-parent when fetching.
-
If you're tracking a directory that has moved, or otherwise been
branched or tagged off of another directory in the repository and you
-care about the full history of the project, then you can read this
-section.
-
-This is how Yann Dirson tracked the trunk of the ufoai directory when
-the /trunk directory of his repository was moved to /ufoai/trunk and
-he needed to continue tracking /ufoai/trunk where /trunk left off.
+care about the full history of the project, then you can use
+the --follow-parent option.
-------------------------------------------------------------------------
- # This log message shows when the repository was reorganized:
- r166 | ydirson | 2006-03-02 01:36:55 +0100 (Thu, 02 Mar 2006) | 1 line
- Changed paths:
- D /trunk
- A /ufoai/trunk (from /trunk:165)
-
- # First we start tracking the old revisions:
- GIT_SVN_ID=git-oldsvn git-svn init \
- https://svn.sourceforge.net/svnroot/ufoai/trunk
- GIT_SVN_ID=git-oldsvn git-svn fetch -r1:165
-
- # And now, we continue tracking the new revisions:
- GIT_SVN_ID=git-newsvn git-svn init \
- https://svn.sourceforge.net/svnroot/ufoai/ufoai/trunk
- GIT_SVN_ID=git-newsvn git-svn fetch \
- 166=`git-rev-parse refs/remotes/git-oldsvn`

BUGS
----
-If you are not using the SVN::* Perl libraries and somebody commits a
-conflicting changeset to SVN at a bad moment (right before you commit)
-causing a conflict and your commit to fail, your svn working tree
-($GIT_DIR/git-svn/tree) may be dirtied. The easiest thing to do is
-probably just to rm -rf $GIT_DIR/git-svn/tree and run 'rebuild'. You
-can avoid this problem entirely by using 'dcommit'.
-
We ignore all SVN properties except svn:executable. Too difficult to
map them since we rely heavily on git write-tree being _exactly_ the
same on both the SVN and git working trees and I prefer not to clutter
# The default target of this Makefile is...
-all:
+all::
# Define NO_OPENSSL environment variable if you do not have OpenSSL.
# This also implies MOZILLA_SHA1.

# Define NO_MMAP if you want to avoid mmap.

+# Define NO_PREAD if you have a problem with pread() system call (e.g.
