Dear Wolfgang,

I am extremely thankful to you for your message this morning 
and the so valuable differential-equations-related information
brought to my attention, which I have been unaware. I have 
already downloaded some of the related files (following your
instructions) and I plan to study them in some detail before 
being able to experiment with them. (My experience with
Maxima, you know, is still very low.)

I tool also into account your comment that

> `Of course, those packages were written for the commercial 
> Macsyma . . .'

which is, to be sincere, disappointing for me since it forbids me
to distribute these files to my students, since they belong to the
commercial Macsyma. I have also been able to verify in some
of them not only the Copyright sign by the authors prohibiting
reproduction, but also the additional sign.

MACSYMA copyright and trademark: Macsyma, Inc.,
Arlington, Ma, USA

Therefore, I am afraid, the best that can be done with these
files is personal, unofficial use and by no means distribution.

In spite of this situation, I am sure, studying the content
of these files, I will learn a lot about the possibilities of 
Maxima around differential equations and this will be 
very helpful to me in my tasks at the University of Patras.

Please, accept again my gratitude for your help. This is
greatly appreciated.

Best regards from Patras,

Nikos
