Hi Wolfgang,

I appreciate your solution, but it would be much more useful if the 
solution would be accompanied with a step-by-step explanation of what is 
going on behind the scenes.

A collection of such elegant solutions (together with explanations) 
would be an invaluable source of knowledge for those of us who want to 
learn the TeX programming.
