old plugins : professor, tablor

Hi,

I did a 2 hours training for young math teachers and will do some more
training for maths and physics teachers in my town. With the success
TeXmacs encounters, and for my next training I wanted to revive some old
but really useful plugins produce by Emmanuël Corcelle. Specifically, I'd
like to know if it is possible to make professor, tablor and figures work
again : I tried several tricks but without any success.

I join here the old plugins I saved on my HHD (and that I can't find on the
net any longer). The webpages explaining the plugins are :

Thanks for your help.
