UsageLine: "create <name> from mirror <mirror-name> | create <name> empty",

Short: "creates immutable snapshot of mirror contents",
|
|
Long: `
|
|
Command create .. 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 .. 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.

$ aptly snapshot create wheezy-main-today from mirror wheezy-main
