"""update.py for dnsmasq-devel - (C) 2025 Matthias Andree, placed under MIT license
To use, edit Makefile with the new version,
then run files/update.py, which will download, check sigs, if GnuPG checks out, update makesum,
upload tarball and sig to my public_distfiles/ because upstream has low bandwidth, and test build.

If things work out, commit manually and push."""
