   3  # An example hook script to prepare the commit log message.
   4  # Called by "git commit" with the name of the file that has the
   5  # commit message, followed by the description of the commit
   6  # message's source.  The hook's purpose is to edit the commit
   7  # message file.  If the hook fails with a non-zero status,
   8  # the commit is aborted.
   9  #
  10  # To enable this hook, rename this file to "prepare-commit-msg".
  11  
  12  # This hook includes three examples. The first one removes the
  13  # "# Please enter the commit message..." help message.
  14  #
  15  # The second includes the output of "git diff --name-status -r"
  16  # into the message, just before the "git status" output.  It is
  17  # commented because it doesn't cope with --amend or with squashed
  18  # commits.
  19  #
  20  # The third example adds a Signed-off-by line to the message, that can
  21  # still be edited.  This is rarely a good idea.
