+git hooks for anaconda development
+
+commit-msg
+    For rhel*-branch branches, ensures that commits reference an
+    approved RHEL bug for the appropriate release in the correct
+    format.
+
+    To use, copy this script to your .git/hooks directory and make
+    sure you have the python-bugzilla package installed.  You might
+    also want to create a ~/.rhbzauth file containing two shell
+    variables:  RHBZ_USER and RHBZ_PASSWORD to allow automatic login
+    when commiting patches.

+#!/bin/sh
+#
+# An example hook script to check the commit log message.
+# Called by git-commit with one argument, the name of the file
+# that has the commit message.  The hook should exit with non-zero
+# status after issuing an appropriate message if it wants to stop the
+# commit.  The hook is allowed to edit the commit message file.
+#
+# To enable this hook, make this file executable.
+
+# Uncomment the below to add a Signed-off-by line to the message.
+# SOB=$(git var GIT_AUTHOR_IDENT | sed -n 's/^\(.*>\).*$/Signed-off-by: \1/p')
+# grep -qs "^$SOB" "$1" || echo "$SOB" >> "$1"
+
+# This example catches duplicate Signed-off-by lines.
+
+test "" = "$(grep '^Signed-off-by: ' "$1" |
+	 sort | uniq -c | sed -e '/^[ 	]*1[ 	]/d')" || {
