# 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.
