-NAME
-----
-git-notes - Add/inspect commit notes
-
-SYNOPSIS
---------
-[verse]
-'git-notes' (edit | show) [commit]
-
-DESCRIPTION
------------
-This command allows you to add notes to commit messages, without
-changing the commit.  To discern these notes from the message stored
-in the commit object, the notes are indented like the message, after
-an unindented line saying "Notes:".
-
-To disable commit notes, you have to set the config variable
-core.notesRef to the empty string.  Alternatively, you can set it
-to a different ref, something like "refs/notes/bugzilla".  This setting
-can be overridden by the environment variable "GIT_NOTES_REF".
-
-
-SUBCOMMANDS
------------
-
-edit::
-	Edit the notes for a given commit (defaults to HEAD).
-
-show::
-	Show the notes for a given commit (defaults to HEAD).
