+// Example of HTTPServer with additional features:
+// * Link status indication (LED4)
+// * Local file system (create index.htm page on MBED!)
+// * RPC-able class (myrpc, allows remote function call that blinks LED1 N times)
+//
+// Instructions:
+// 1  Plug MBED into BoB2 (or other ETH connector breakout)
+// 2  Plug ETH connector into your network (needs DHCP to get IP address)
+// 3  Power up MBED using USB cable
+// 4  Install MBED serial driver (http://mbed.org/handbook/SerialPC)
+// 5  Copy compiled .bin to your MBED (make sure target device selected in the compiler is correct)
+// 6  Open terminal on the mbed serial port
+// 7  Push MBED reset button
+// 8  Terminal will display info message with mac address, followed by IP address (if connection succeeds)
+// 9  Open browser and enter the following URL, inserting your MBED's IP address:
+//    http://10.0.0.321/rpc/myrpc1/blink,10 (instead of 10.0.0.321 use MBED IP address from terminal)
+// 10 MBED will blink the LED 10 times
+//
+// Notes: there are still some bugs in HTTPServer code. 
+// To help fight some of them, copy a valid favicon.ico (a 16x16 icon) file to MBED.
