+     "SIP is a tool to create Python bindings for C and C++ libraries.  It
+was originally developed to create PyQt, the Python bindings for the Qt
+toolkit, but can be used to create bindings for any C or C++ library.
+
+SIP comprises a code generator and a Python module.  The code generator
+processes a set of specification files and generates C or C++ code, which
+is then compiled to create the bindings extension module.  The SIP Python
+module provides support functions to the automatically generated code.")
