Dear all,
Thank you for all your remarks concerning the tutorial.
For a little while, I have started again to rewrite the manual.
It is almost done but I will take your comments into account.
But for the moment, we have to finish the Cormas 2005 version...
The new tutorial should be available with the new Cormas release.
All the best,
Pierre
