#

# An example hook script to prepare the commit log message.

# Called by "git commit" with the name of the file that has the

# commit message, followed by the description of the commit

# message's source.  The hook's purpose is to edit the commit

# message file.  If the hook fails with a non-zero status,

# the commit is aborted.

#

# To enable this hook, rename this file to "prepare-commit-msg".

# This hook includes three examples. The first one removes the

# "# Please enter the commit message..." help message.

#

# The second includes the output of "git diff --name-status -r"

# into the message, just before the "git status" output.  It is

# commented because it doesn't cope with --amend or with squashed

# commits.

#

# The third example adds a Signed-off-by line to the message, that can

# still be edited.  This is rarely a good idea.
