+//! <h1>Ethernet Weather Application (enet_weather)</h1>
+//!
+//! This example application demonstrates the operation of the Tiva C series
+//! evaluation kit as a weather reporting application.
+//!
+//! The application supports updating weather information from Open Weather Map
+//! weather provider(http://openweathermap.org/). The application uses the
+//! lwIP stack to obtain an address through DNS, resolve the address of the
+//! Open Weather Map site and then build and handle all of the requests
+//! necessary to access the weather information. The application can also use
+//! a web proxy, allows for a custom city to be added to the list of cities and
+//! toggles temperature units from Celsius to Fahrenheit. The application
+//! scrolls through the city list at a fixed interval when there is a valid
+//! IP address and displays this information over the UART.
+//!
+//! The application will print the city name, status, humidity, current temp
+//! and the high/low. In addition the application will display what city it
+//! is currently updating. Once the app has scrolled through the cities a
+//! a defined amount of times, it will attempt to update the information.
+//!
+//! UART0, connected to the Virtual Serial Port and running at 115,200, 8-N-1,
+//! is used to display messages from this application.
+//!
+//!/ For additional details about Open Weather Map refer to their web page at:
+//! http://openweathermap.org/
+//!
+//! For additional details on lwIP, refer to the lwIP web page at:
+//! http://savannah.nongnu.org/projects/lwip/

+
+This example application demonstrates the operation of the Tiva C series
+evaluation kit as a weather reporting application.
+
+The application supports updating weather information from Open Weather Map
+weather provider(http://openweathermap.org/). The application uses the
+lwIP stack to obtain an address through DNS, resolve the address of the
+Open Weather Map site and then build and handle all of the requests
+necessary to access the weather information. The application can also use
+a web proxy, allows for a custom city to be added to the list of cities and
+toggles temperature units from Celsius to Fahrenheit. The application
+scrolls through the city list at a fixed interval when there is a valid
+IP address and displays this information over the UART.
+
+The application will print the city name, status, humidity, current temp
+and the high/low. In addition the application will display what city it
+is currently updating. Once the app has scrolled through the cities a
+a defined amount of times, it will attempt to update the information.
+
+UART0, connected to the Virtual Serial Port and running at 115,200, 8-N-1,
+is used to display messages from this application.
+
+/ For additional details about Open Weather Map refer to their web page at:
