-         NILFS2 is a log-structured file system (LFS) supporting continuous
-         snapshotting.  In addition to versioning capability of the entire
-         file system, users can even restore files mistakenly overwritten or
-         destroyed just a few seconds ago.  Since this file system can keep
-         consistency like conventional LFS, it achieves quick recovery after
-         system crashes.
-
-         NILFS2 creates a number of checkpoints every few seconds or per
-         synchronous write basis (unless there is no change).  Users can
-         select significant versions among continuously created checkpoints,
-         and can change them into snapshots which will be preserved for long
-         periods until they are changed back to checkpoints.  Each
-         snapshot is mountable as a read-only file system concurrently with
-         its writable mount, and this feature is convenient for online backup.
-
-         Some features including atime, extended attributes, and POSIX ACLs,
-         are not supported yet.
-
-         To compile this file system support as a module, choose M here: the
-         module will be called nilfs2.  If unsure, say N.
