SIP is a tool for generating bindings for C++ classes so that they can be accessed as normal Python
classes. SIP takes many of its ideas from SWIG but, because it is specifically designed for C++ and
Python, is able to generate tighter bindings. SIP is so called because it is a small SWIG.
SIP was originally designed to generate Python bindings for KDE and so has explicit support for the
signal slot mechanism used by the Qt/KDE class libraries. However, SIP can be used to generate
Python bindings for any C++ class library.
