+Incomplete Debian package implementation.
+It can be used to generate an easily installable Capstone, but misses a lot of
+mandatory things to add it in the Debian repos (`debian/control` is incomplete, no dependencies added etc.).
+
+You can build the package by dispatching the `Build Debian Package` workflow or executing the commands in the `Dockerfile`.
+It assumes the current commit is tagged and `"$(git describe --tags --abbrev=0)"` returns a valid version number.
+The package is uploaded as artifact.
