file in `$GIT_DIR/remotes` directory can be given; the
named file should be in the following format:
+------------
URL: one of the above URL format
Push: <refspec>
Pull: <refspec>
+------------
+
Then such a short-hand is specified in place of
<repository> without <refspec> parameters on the command
line, <refspec> specified on `Push:` lines or `Pull:`
respectively. Multiple `Push:` and `Pull:` lines may
be specified for additional branch mappings.
+Or, equivalently, in the `$GIT_DIR/config` (note the use
+of `fetch` instead of `Pull:`):
+
+------------
+ [remote "<remote>"]
+ url = <url>
+ push = <refspec>
+ fetch = <refspec>
+
+------------
+
The name of a file in `$GIT_DIR/branches` directory can be
specified as an older notation short-hand; the named
file should contain a single line, a URL in one of the
without the fragment is equivalent to have this in the
corresponding file in the `$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>
+------------
