   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.
