Subject: [RFC v3 6/9] Many pages: [GPL-2.0-or-later] Use SPDX markings
Date: Sun,  5 Sep 2021 15:25:39 +0200	[thread overview]
Message-ID: <20210905132542.245236-7-alx.manpages@gmail.com> (raw)
In-Reply-To: <20210905132542.245236-1-alx.manpages@gmail.com>

To simplify understanding which license applies to each file,
let's use SPDX markings, which are simple, informative, and
commonly used in many projects.
Let's also follow REUSE <https://reuse.software/> conventions.
