Install, configure, refresh and remove snap packages. Snaps are
'universal' packages that work across many different Linux systems,
enabling secure distribution of the latest apps and utilities for
cloud, servers, desktops and the internet of things.
This is the CLI for snapd, a background service that takes care of
snaps on the system. Start with 'snap list' to see installed snaps.
