-		The BINFS file system is current just a toy.  The BINFS may, for example,
-		be mount at /bin.  Then all of the built-in applications will appear as
-		executable file in /bin if you list them from NSH like:
-
-		nsh> ls -l /bin
-
-		At present, the BINFS supports nothing more than that.  It is planned,
-		however, to support execution of the builtin applications from BINFS as
-		well (via a binfmt/ loader).  However, that is down the road.
