   3 # An example hook script to check the commit log message.
   4 # Called by git-commit with one argument, the name of the file
   5 # that has the commit message.  The hook should exit with non-zero
   6 # status after issuing an appropriate message if it wants to stop the
   7 # commit.  The hook is allowed to edit the commit message file.
   8 #
   9 # To enable this hook, make this file executable.

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