+# An example hook script to check the commit log message.
+# Called by git-commit-script 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.
+
+# This example catches duplicate Signed-off-by lines.
