Hi Rainer,

You are very close, the problem is that the code block whose header
argument initiates the tangling should not itself be tangled, otherwise
you will wind up with the infinite recursion error you've noticed.

A setup like the following should work...

Works perfectly - I especially like the summary of the tangling via wc $= TANGLED - very nice side effect.

Thanks a lot,

Rainer
