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
dofile 'plot.lua'.

..\gsl_shell plot.lua

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
syntax was supported in vanilla Lua. A very convenient bit of
syntactical sugar if you are fond of the functional style.
