ifacetool provides tooling to work with snap interfaces, in
particular their policies as realized via snap-declarations.
One central feature of ifacetool is simulating what snapd will
do in terms of auto-connections for a group of snaps given snap
metadata and snap-declaration content.
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
