+          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.
