+fs/binfs README
+================
+
+  This is the binfs file system that allows "fake" execution of NSH built-
+  in applications via the file system.  The binfs fs file system can be
+  built into the system by enabling:
+
+    CONFIG_BUILTIN=y
+    CONFIG_FS_BINFS=y
+
+  It can then be mounted from the NSH command like like:
+
+   mount -t binfs /bin
+
+Example
+=======
+
+  NuttShell (NSH) NuttX-6.31
+  nsh> hello
+  nsh: hello: command not found
+
+  nsh> mount -t binfs /bin
+  nsh> ls /bin
+  ls /bin
+  /bin:
+   hello
+
+  nsh> /bin/hello
+  Hello, World!!
