  * basic demo.  Generic functions, such FreeRTOS hook functions, and functions\r

  ******************************************************************************\r
+ *\r
+ * The lwIP example can be configured to use either a static or dynamic IP\r
+ * address:\r
+ *    + To use a dynamically allocated IP address set LWIP_DHCP to 1 in\r
+ *      lwipopts.h and connect the target to a network that includes a DHCP\r
+ *      server.  The obtained IP address is printed to the UART console.\r
+ *    + To use a static IP address set LWIP_DHCP to 0 in lwipopts.h and set\r
+ *      the static IP address using the configIP_ADDR0 to configIP_ADDR3\r
+ *      constants at the bottom of FreeRTOSConfig.h.  Constants used to define\r
+ *      a netmask are also located at the bottom of FreeRTOSConfig.h.\r
+ *\r
+ * When connected correctly the demo uses the lwIP sockets API to create\r
+ * a FreeRTOS+CLI command console, and the lwIP raw API to create a create a\r
+ * basic HTTP web server with server side includes that generate dynamic run\r
+ * time web pages.  See http://www.freertos.org/RTOS-Xilinx-Zynq.html for more\r
+ * information.\r
