-netconfig
-^^^^^^^^^
-This alternative configuration file, netconfig, may be used
-instead of the default configuration (defconfig). This
-configuration enables networking using the c5471's built-in
-Ethernet interface.  It uses examples/nettest to excercise

-^^^^^^^^^
-This configuration file builds NSH (examples/nsh) using the
-TELNET server front end
+Where <subdir> is one of the following.
+
+By default, all configurations assume the NuttX Buildroot toolchain under
+Linux (should work under Windows with Cygwin as well).

+nettest
+-------
+
+  This configuration enables networking using the c5471's built-in Ethernet
+  interface.  It uses examples/nettest to exercise the TCP/IP network.

-^^^^^^^^^^
-This configuration exercises the DHCP client of netutils/dhcpc
-using examples/uip.

-These alternative configurations can be selected by (using

-	(Seleted the default configuration as show above)
-	cp config/c5471evm/uiponfig .config
