+This hook is called by 'git rebase' and can be used to prevent a

+two parameters. The first parameter is the upstream from which
+the series was forked. The second parameter is the branch being

+pre-push
+~~~~~~~~
+
+This hook is called by 'git push' and can be used to prevent a push from taking
+place. The hook is called with two parameters which provide the name and
+location of the destination remote, if a named remote is not being used both
+values will be the same.
+
+Information about what is to be pushed is provided on the hook's standard
+input with lines of the form:
+
+ <local ref> SP <local sha1> SP <remote ref> SP <remote sha1> LF
+
+For instance, if the command +git push origin master:foreign+ were run the
+hook would receive a line like the following:
+
+ refs/heads/master 67890 refs/heads/foreign 12345
+
+although the full, 40-character SHA1s would be supplied. If the foreign ref
+does not yet exist the `<remote SHA1>` will be 40 `0`. If a ref is to be
+deleted, the `<local ref>` will be supplied as `(delete)` and the `<local
+SHA1>` will be 40 `0`. If the local commit was specified by something other
+than a name which could be expanded (such as `HEAD~`, or a SHA1) it will be
+supplied as it was originally given.
+
+If this hook exits with a non-zero status, 'git push' will abort without
+pushing anything. Information about why the push is rejected may be sent
+to the user by writing to standard error.
