[Bug-apl] ⎕GTK

[Juergen Sauermann]

Hi,

I have added a new system function ⎕GTK to GNU APL.

⎕GTK is based on libgtk+ version 3 and provides a simple (and
therefore somewhat restricted) way of creating and  managing GUIs
from an APL program.

Think of it as a replacement for ⎕ and ⍞ as to create more intuitive
user interfaces to APL programs.

⎕GTK is described in HOWTOs/Quad-GTK.html.

Enjoy,
