Here is a patch to add Appstream metainfo XML announcing the hardware
handled by this package.

Including this information in the package will ensure programs mapping
hardware to packages using Appstream information, like the isenkram
package, will know that this package is useful on machines where the
hardware is discovered.

The appstream metadata file can be checked using this command after
package build:

  appstreamcli validate-tree  --no-net --explain debian/gpsbabel-gui

Hi Petter,

this sounds like upstream should maintain it so could you please send it
to them, if you did not already?

Also gpsbabel supports a lot of hardware devices so the list should
probably be longer.

Cheers Jochen

I agree that upstream is probably a good actor to maintain this, and
perhaps even know better than me which hardware should be listed.  I did
not send it to upstream, and is unlikely to give it priority before I am
done submitting patches to Debian for the remaining 40 packages I need
to go through with appstream modalias provide fixes.

I've send a slightly modified patch upstream.
