The author has worked again and again with and on this fantastic product since the beginnings of LEDA at the end of the eighties. These days, he is working as a freelance software developer, IT-instructor and author.
One motivation for writing this tutorial was to create a course material with which LEDA trainings can be held. For such trainings, the author is available any time (and of course also for trainings in other IT topics, for project work with and without use of LEDA, simply for everything really groovy); one can hire him.
