For details about packaging see https://wiki.debian.org/Cinnamon/Packaging

Upstream is split across two repositories:

  * https://github.com/linuxmint/iso-country-flags-svg-collection
    The actual SVG sources we ship. It carries no tags or releases.

  * https://github.com/linuxmint/flags
    Only generated icons (a single format), but this is where upstream
    publishes the versioned releases (tags 1.0.x).

The package version follows the "flags" release tags, while the upstream
tarball is built manually from the matching commit of
iso-country-flags-svg-collection. debian/watch points at "flags" only to
let the Debian QA infrastructure report new upstream versions; do not run
uscan to download or import the source, as the "flags" tarball is the wrong
content.
