This is SWIG 1.1 (Simplified Wrapper and Interface Generator)
packaged for Debian GNU/Linux.

This package is compiled with support for Tcl, Tcl8.0, Python,
Perl5 and Guile. The package also contains the runtime libraries
needed for larger packages.

I added a patch submitted by Drake Diedrich <Drake.Diedrich@anu.edu.au> 
to support polymorphic return types for C++/Perl bindings. It was applied 
upstream to the development version but there is no new stable release 
yet. If you installed the swig-examples package you can find his example 
applications in /usr/doc/swig/examples/perl5/polymorph.
