IIRC, the old tutorial used plain X -- I'm not sure about the licensing 
conditions, but at least this is also not a GNU package, right?  And 
you're right that the license does not really sound very "free", now 
that I read it in detail; thanks for pointing this out!

However, I did not know what a good alternative would have been -- but 
if you have one, I will be happy to adapt the tutorial when I find time 
to do so.

I think this may really be a good idea, provided that there is some kind 
of prominent notice it is not only "old" but also uses deprecated API -- 
thus not only "old" in the sense that something "newer" is available but 
also that new users really should not learn the stuff using that one.  I 
hope you understand what I mean here.
