Subject: [PATCH] =?UTF-8?q?=E2=9C=A8=20Add=20automated=20tagged=20releases?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Using woodpecker ci most of the release process is now automated.
That means as soon as a new version tag (e.g. `v0.2.3`) is pushed the
release process is started and will (if versions have been bumped
correctly) set up a new release on Gitea and Github simultaneously.

The release process will fail if changelog and program versions
mismatch, or the version has not been bumped in general.

The release contains the executable and some documentation, including
the README as a manpage-formatted gzip file which can be included in the
correct directory to enable a simple manpage for the program.
