# When updating this package, my process is:
#  - download the "official" binary from https://github.com/hlandau/acme/releases
#  - run `$dir/bin/acmetool --version|sed -n 's/^git //p'|column -t`
#  - paste that into the _source table below
#  - move the `github.com/hlandau/acme` line to the top, change the git-describe to `v$pkgver`
#  - insert/update the license info for each
