+management.  Apart from the obvious creation and deletion of snapshots, 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.
+
+The features include:
+
+@itemize
+@item Manually create snapshots.
+@item Automatically create snapshots.
+@item Automatically create timeline of snapshots.
+@item Show and revert changes between snapshots.
+@item Works with btrfs, ext4 and thin-provisioned LVM volumes.
+@item Supports Access Control Lists and Extended Attributes.
+@item Automatic cleanup of old snapshots.
+@item Command line interface.
+@item D-Bus interface.
+@item PAM module to create snapshots during login and logout.
