  22.  * Well, this is a more elaborate example how to create a neat little page
  23.  * with fetching data from weather.com and putting it into a design.
  24.  * I'm not too proud of my design-skills, most of the stuff here is taken
  25.  * from the weather-block which can be found within the Horde Framework,
  26.  * courtesy of Rick Emery - creative pixelshoving isn't my domain :-P
  27.  * I've used a Firefox for checking the design, so don't be too
  28.  * disappointed, if the page looks shabby with the IE, not that I care
  29.  * very much anyway ;-)
  30.  * If you want to know where you can obtain the icons, please register at
  31.  * http://www.weather.com/services/xmloap.html and you'll receive an eMail
  32.  * containing the partner id, the license key and a link pointing to the
  33.  * SDK. Put the 32x32 and the logos folders into the images/ directory.
  34.  * The design should adhere to the conventions defined by the weather.com
  35.  * SDK-guide, though I won't give any legal certainty for this (of course).
  36.  * Have fun!
