Comment 3 for bug 1594794

Launchpad needs more dynamic snap support. Currently, it only builds snaps from branches with a static snapcraft.yaml file in the root. Instead, it needs to invoke a build script of some sort (Makefile, executable with a well known name). This script could, for example, extract version numbers from debian/changelog or setup.py, install build dependencies, generate a snapcraft.yaml, run snapcraft to build, run tests. It would even be possible, if Launchpad allows, to build several related snaps and, only if tests pass, upload them all to the store.
