#
# 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.

# This example catches duplicate Signed-off-by lines.
