Notes

On Ubuntu 17.10 the SciLab GUI gave error:

Cannot find this look and feel:
[GTK look and feel - com.sun.java.swing.plaf.gtk.GTKLookAndFeel] not supported on this platform
Segmentation fault (core dumped)

This error is experienced on Gentoo and Ubuntu 17.10 among other platforms. The Scilab bug tracker says to compile Scilab yourself.
