This example was created to show the use of tcluno for in an article for
the german computer magazin [http:www.LinuxMagazin.de|LinuxMagazin]. Variables are therefore in german,
but I hope the example is usefull for non german speakers as well.

It show the usage of the itcluno extension found at [http://tcluno.sourceforge.net|tcluno]
using the pure scripting solution tclurtp. 

The example creates a spreadsheet with the water level at Hamburg-Harburg, Germany
including a simple chart.

Besides installing itcluno it requires that you start OpenOffice with 
network support. This could be done by starting OpenOffice using

ooffice \"-accept=socket,host=localhost,port=2002;urp;
