I'm done, Oberon, but must correct a biblical
legion of typos, which I will do tomorrow. So tomorrow it is, I think. So far I counted six words not having a typo in them, and all six consisted of one or two letters.
I really should have the Max Planck institute checking my typing technique. Somewhere in there there's a problem, it seems.
I'm not used to this kind of thing anymore, I really feel the lacking practice. Or I just become old.

Shouldn't have allowed the forum to civilize me.
