DESCRIPTION
-----------
-Fetches a named head or a tag from another repository, along

+ argument to "git-cat-file -t". E.g. "master~4" (push
+ four parents before the current master head).
+
+ 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/pull", 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
+ is updated even if it does not result in a fast forward
+ update.
+
+ 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>".
+
+ * 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.
