-      btrfs-auto-snapshot is a Bash script designed to bring as much of the
-      functionality of the wonderful ZFS snapshot tool zfs-auto-snapshot to
-      BTRFS as possible. Designed to run from cron (using
-      /etc/cron.{daily,hourly,weekly}) it automatically creates a snapshot of
-      the specified BTRFS filesystem (or, optionally, all of them) and then
-      automatically purges the oldest snapshots of that type (hourly, daily, et
-      al) based on a user-defined retention policy.
-
-      Snapshots are stored in a '.btrfs' directory at the root of the BTRFS
-      filesystem being snapped and are read-only by default.
