     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.
