Yes, maybe it's best to not introduce the tutorial as an "integral part"
of the manual -- but rather as a seperate item, which may be referred to
or linked to in the manual.  what do you think?

I also have this impression, unfortunately.  But if you see a "good" way
to do the visualization instead of forking gnuplot, I'm happy to adapt
the tutorial.

Well, *that* looks really cool!  I have to give it a try soon :D  Do you
have a suggestion for how to integrate this with the manual?  It seems
to me that with such a small project it does not make sense to do both
registering procedures from C and using the FFI.  But maybe we could
just call some libc function at one place?  Although I have no idea so far.

Yours,
Daniel
