<repository>::
The "remote" repository that is the source of a fetch
- or pull operation, or the destination of a push operation.
- One of the following notations can be used
- to name the remote repository:
-+
-===============================================================
-- Rsync URL: rsync://remote.machine/path/to/repo.git/
-- HTTP(s) URL: http://remote.machine/path/to/repo.git/
-- git URL: git://remote.machine/path/to/repo.git/
- or remote.machine:/path/to/repo.git/
-- Local directory: /path/to/repo.git/
-===============================================================
-+
-In addition to the above, as a short-hand, the name of a
-file in `$GIT_DIR/remotes` directory can be given; the
-named file should be in the following format:
-+
- URL: one of the above URL format
- Push: <refspec>
- Pull: <refspec>
-+
-When such a short-hand is specified in place of
-<repository> without <refspec> parameters on the command
-line, <refspec> specified on `Push:` lines or `Pull:`
-lines are used for `git-push` and `git-fetch`/`git-pull`,
-respectively. Multiple `Push:` and and `Pull:` lines may
-be specified for additional branch mappings.
-+
-The name of a file in `$GIT_DIR/branches` directory can be
-specified as an older notation short-hand; the named
-file should contain a single line, a URL in one of the
-above formats, optionally followed by a hash `#` and the
-name of remote head (URL fragment notation).
-`$GIT_DIR/branches/<remote>` file that stores a <url>
-without the fragment is equivalent to have this in the
-corresponding file in the `$GIT_DIR/remotes/` directory.
-+
- URL: <url>
- Pull: refs/heads/master:<remote>
-+
-while having `<url>#<head>` is equivalent to
-+
- URL: <url>
- Pull: refs/heads/<head>:<remote>
+ or pull operation. This parameter can be either a URL
+ (see the section <<URLS,GIT URLS>> below) or the name
+ of a remote (see the section <<REMOTES,REMOTES>> below).
<refspec>::
- The canonical format of a <refspec> parameter is
- `+?<src>:<dst>`; that is, an optional plus `+`, followed
- by the source ref, followed by a colon `:`, followed by
- the destination ref.
-+
-When used in `git-push`, the <src> side can be an
-arbitrary "SHA1 expression" that can be used as an
-argument to `git-cat-file -t`. E.g. `master~4` (push
-four parents before the current master head).
+ The format of a <refspec> parameter is an optional plus
+ `{plus}`, followed by the source ref <src>, followed
+ by a colon `:`, followed by the destination ref <dst>.
+
-For `git-push`, the local ref that matches <src> is used
-to fast forward the remote ref that matches <dst>. If
-the optional plus `+` is used, the remote ref is updated
-even if it does not result in a fast forward update.
-+
-For `git-fetch` and `git-pull`, the remote ref that matches <src>
+The remote ref that matches <src>
is fetched, and if <dst> is not empty string, the local
ref that matches it is fast forwarded using <src>.
-Again, if the optional plus `+` is used, the local ref
+If the optional plus `+` is used, the local ref
is updated even if it does not result in a fast forward
update.
+
[NOTE]
You never do your own development on branches that appear
on the right hand side of a <refspec> colon on `Pull:` lines;
-they are to be updated by `git-fetch`. If you intend to do
+they are to be updated by 'git-fetch'. If you intend to do
development derived from a remote branch `B`, have a `Pull:`
line to track it (i.e. `Pull: B:remote-B`), and have a separate
branch `my-B` to do your development on top of it. The latter
the progress of the remote side, and when you see something new
on the remote branch, merge it into your development branch with
`git pull . remote-B`, while you are on `my-B` branch.
-The common `Pull: master:origin` mapping of a remote `master`
-branch to a local `origin` branch, which is then merged to a
-ocal development branch, again typically named `master`, is made
-when you run `git clone` for you to follow this pattern.

[NOTE]
There is a difference between listing multiple <refspec>
-directly on `git-pull` command line and having multiple
+directly on 'git-pull' command line and having multiple
`Pull:` <refspec> lines for a <repository> and running
-`git-pull` command without any explicit <refspec> parameters.
+'git-pull' command without any explicit <refspec> parameters.
<refspec> listed explicitly on the command line are always
merged into the current branch after fetching. In other words,
if you list more than one remote refs, you would be making
-an Octopus. While `git-pull` run without any explicit <refspec>
+an Octopus. While 'git-pull' run without any explicit <refspec>
parameter takes default <refspec>s from `Pull:` lines, it
merges only the first <refspec> found into the current branch,
after fetching all the remote refs. This is because making an

Some short-cut notations are also supported.

-* For backward compatibility, `tag` is almost ignored;
- it just makes the following parameter <tag> to mean a
- refspec `refs/tags/<tag>:refs/tags/<tag>`.
+* `tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`;
+ it requests fetching everything up to the given tag.
* A parameter <ref> without a colon is equivalent to
- <ref>: when pulling/fetching, and <ref>`:`<ref> when
- pushing. That is, do not store it locally if
- fetching, and update the same name if pushing.
