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.
