+ * UIPEthernet EchoServer example.
+ *
+ * UIPEthernet is a TCP/IP stack that can be used with a enc28j60 based
+ * Ethernet-shield.
+ *
+ * UIPEthernet uses the fine uIP stack by Adam Dunkels <adam@sics.se>
+ *
+ *      -----------------
+ *
+ * This Hello World example sets up a server at 192.168.1.6 on port 1000.
+ * Telnet here to access the service.  The uIP stack will also respond to
+ * pings to test if you have successfully established a TCP connection to
+ * the Arduino.
+ *
+ * This example was based upon uIP hello-world by Adam Dunkels <adam@sics.se>
+ * Ported to the Arduino IDE by Adam Nielsen <malvineous@shikadi.net>
+ * Adaption to Enc28J60 by Norbert Truchsess <norbert.truchsess@t-online.de>
