Short: "creates snapshot of mirror (local repository) contents",
Long: `
Command create <name> from mirror makes persistent immutable snapshot of remote
repository mirror. Snapshot could be published or further modified using
merge, pull and other aptly features.
Command create <name> from repo makes persistent immutable snapshot of local
repository. Snapshot could be processed as mirror snapshots, and mixed with
snapshots of remote mirrors.
Command create <name> empty creates empty snapshot that could be used as a
basis for snapshot pull operations, for example. As snapshots are immutable,
creating one empty snapshot should be enough.
Example:
$ aptly snapshot create wheezy-main-today from mirror wheezy-main
