Well done, Francesco! The plots are indeed good looking, and I'm glad
that you avoided the old Gnuplot mess.
Being lazy and overworked, I took the easy way out, tried out the
Windows binaries. To get the plot demos working, I had to open a
command shell in the examples directory, run ..\gsl-shell and then use
Does not work directly, but does if you put 'io.read()' as the last
line to prevent the process from just dying.
PS the more I play with things like |x| x*(x-1), I wish that this
