Title: GTK+2.0 Tutorial
Author: Tony Gale and Ian Main
Abstract: GTK+ (GIMP Toolkit) is a library for creating graphical user
interfaces. It is licensed using the LGPL license, so you can develop
open software, free software, or even commercial non-free software
using GTK+ without having to spend anything for licenses or royalties.
This tutorial is an attempt to document as much as possible of GTK+,
but it is by no means complete. This tutorial assumes a good
understanding of C, and how to create C programs. It would be a great
benefit for the reader to have previous X programming experience, but
it shouldn't be necessary.
