+//config:	  NILFS is a New Implementation of a Log-Structured File System (LFS)
+//config:	  that supports continuous snapshots. This provides features like
+//config:	  versioning of the entire filesystem, restoration of files that
+//config:	  were deleted a few minutes ago. NILFS keeps consistency like
+//config:	  conventional LFS, so it provides quick recovery after system crashes.
+//config:
+//config:	  The possible use of NILFS includes versioning, tamper detection,
+//config:	  SOX compliance logging, and so forth. It can serve as an alternative
+//config:	  filesystem for Linux desktop environment, or as a basis of advanced
+//config:	  storage appliances.
