repository. For pull operations, see 'git-fetch-pack' and
'git-clone-pack'.
+The command allows for creation and fast forwarding of sha1 refs
+(heads/tags) on the remote end (strictly speaking, it is the
+local end receive-pack runs, but to the user who is sitting at
+the send-pack end, it is updating the remote. Confused?)
+
+Before each ref is updated, if $GIT_DIR/hooks/update file exists
+and executable, it is called with three parameters:
+
+ $GIT_DIR/hooks/update refname sha1-old sha1-new
+
+The refname parameter is relative to $GIT_DIR; e.g. for the
+master head this is "refs/heads/master". Two sha1 are the
+object names for the refname before and after the update. Note
+that the hook is called before the refname is updated, so either
+sha1-old is 0{40} (meaning there is no such ref yet), or it
+should match what is recorded in refname.
+
+The hook should exit with non-zero status if it wants to
+disallow updating the named ref. Otherwise it should exit with
+zero.
+
+Using this hook, it is easy to generate mails on updates to
+the local repository. This example script sends a mail with
+the commits pushed to the repository:
+
+ #!/bin/sh
+ # mail out commit update information.
+ if expr "$2" : '0*$' >/dev/null
+ then
+ echo "Created a new ref, with the following commits:"
+ git-rev-list --pretty "$2"
+ else
+ echo "New commits:"
+ git-rev-list --pretty "$3" "^$2"
+ fi |
+ mail -s "Changes to ref $1" commit-list@mydomain
+ exit 0
+
+Another hook $GIT_DIR/hooks/post-update, if exists and
+executable, is called with the list of refs that have been
+updated. This can be used to implement repository wide cleanup
+task if needed. The exit code from this hook invocation is
+ignored; the only thing left for git-receive-pack to do at that
+point is to exit itself anyway. This hook can be used, for
+example, to run "git-update-server-info" if the repository is
+packed and is served via a dumb transport.
+
+ #!/bin/sh
+ exec git-update-server-info
