     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 comments out the

    13 # "Conflicts:" part of a merge commit.

    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.
