wxPython is a GUI toolkit for the Python programming language.  It allows
Python programmers to create programs with a robust, highly functional
graphical user interface simply and easily.  It is implemented as a Python
extension module (native code) that wraps the popular wxWidgets cross
platform GUI library which is written in C++.

If you want support for gnomeprint pass GNOMEPRINT=yes to the script. This
will require libgnomeprint and libgnomeprintui, both available from
SlackBuilds.org.

Another optional dependency is libmspack, which is used by the CHM help
viewer.

wxPython is a port of wxWidgets and as such compatible to other ports like
wxGTK and wxX11.
