Managing snaps
Interacting with the Gallery
snap gallery list will retrieve all the snaps in the gallery:

snap gallery get {snapname} will get the description of a snap. The snap definition
language is a YAML syntax documented elsewhere.

snap snaps fork {snapname} will fork a public snap into the user's account.
Managing your own snaps
snap snaps list will list all snaps in the user's account.
snap snaps get {snapname} will get the description of a snap in the YAML syntax.
snap snaps delete {snapname} will delete a snap from the user's account.
snap snaps publish/unpublish {snapname} will make a snap public (discoverable) or switch it back to private.
