Subject: [PATCH 31/34] watch: use our own "git credential" wrapper
Date: Sat, 27 Jun 2020 10:03:57 +0000 [thread overview]
Message-ID: <20200627100400.9871-32-e@yhbt.net> (raw)
In-Reply-To: <20200627100400.9871-1-e@yhbt.net>
Git.pm may not be installed on some systems; or some users have
multiple Perl installations and Git.pm is not available to the
Perl running -watch. Accomodate both those types of users by
providing our own "git credential" wrapper.
