Gambas graphical toolkit selector

 Gambas is a free development environment based on a Basic interpreter
 with object extensions, like Visual Basic(tm) (but it is NOT a clone!).
 .
 This package just loads gb.gtk3 or gb.qt5.
 It will make your application more desktop-friendly!
 If the GB_GUI environment variable is set, then gb.gui will load the
 component specified by its contents.
