+/** @file
+  SMM Fault Tolerant Write protocol is related to EDK II-specific implementation of FTW,
+  provides boot-time service for fault tolerant write capability for block devices in
+  EFI SMM environment.  The protocol provides for non-volatile storage of the intermediate
+  data and private information a caller would need to recover from a critical fault,
+  such as a power failure.
