As much as I like your way and as much as I would like to understand it
better, I would prefer a more general C or even better C++ tutorial.
Making the work easier with XML and Perl might be too off-topic in the
tutorial I am thinking of. It simply a next step, that should come
in Tutorial Pt. II. But to anyone already familiar with Part I, your
tutorial would be great, of course
(The makestub.pl indeed needs a cleanup. I found myself constantly
cleaning up my Perl code, so I am now happily learning and coding in
Python, but that shall not start a Perl-Python discussion, please.)

I looked into analogueosc source now, and you're simply right.
