To illustrate various SWIG features, the following examples involve
building an interface to a small, but somewhat useful graphics library
for creating 2D and 3D images in the form of GIF files. The Perl,
Python, and Tcl directories contain various examples specific to those
languages.
Python, Tcl, and Ruby directories contain various examples specific to

This library was originally developed as part of the SPaSM molecular
dynamics project at Los Alamos National Laboratory. However, due to

This example runs the entire gifplot.h header file through SWIG without
any changes. The script 'runme.rb' does something a little more
interesting. You'll have to go look at the header file to get a complete
listing of the functions.

This is a very minimalistic example in which just a few functions
and constants from library are wrapped and used to draw some simple
shapes. The script 'runme.rb' runs the example.
