This is the simplestreams ubuntu packaging branch.  It comes from:
 git clone https://git.launchpad.net/simplestreams

The upstream (master) branch does not include debian/changelog but it
can built with ./tools/build-deb.

simplestreams maintains debian packaging for ubuntu in a branch
named 'ubuntu/devel'.  It uses a tool called 'new-upstream-snapshot' [1]
(also used by cloud-init) to create new upstream snapshots for release
to ubuntu.
