This example demonstrates how Pyrex-generated code can be called directly from a main program written in C. In this example, the module's initialisation function (called "initembedded", since the module is called "embedded") is called explicitly. This is necessary because the module is not being imported using the normal Python import mechanism. The Windows makefiles were contributed by Duncan Booth <Duncan.Booth@SuttonCourtenay.org.uk>.
