/*
* Well, this is a more elaborate example how to create a neat little page
* with fetching data from weather.com and putting it into a design.
* I'm not too proud of my design-skills, most of the stuff here is taken
* from the weather-block which can be found withing the Horde Framework,
* courtesy of Rick Emery - creative pixelshoving isn't my domain :-P
* I've used a Firefox for checking the design, so don't be too
* disappointed, if the page looks shabby with with the IE, not that I care
* very much anyway ;-)
* If you want to know where you can obtain the icons, please register at
* http://www.weather.com/services/xmloap.html you'll recive an eMail
* containing the partner id, the license key and a link pointing to the
* SDK. Put the 32x32 and the logos folders into the images/ directory.
* Have fun!
