GS - the Erlang Graphic System
As most of you know, GS is an incomplete interface to tcl/tk. It does not provide a visual GUI builder that generates code. To use it, you have to code all the objects that go on the page, including relative positions and sizes, together with all the various options that a visual object of that type can have (colors, fonts, etc.).
I have taken the GS User's Guide apart and put the pieces back together in a way that should be very helpful to someone who is trying to learn or trying to use GS.
