      A graphical user interface for the tool snapper for Linux filesystem
      snapshot management. It can compare snapshots and revert differences between snapshots.
      In simple terms, this allows root and non-root users to view older versions of files
      and revert changes. Currently works with btrfs, ext4 and thin-provisioned LVM volumes.
