>I'm currently building an application in which I needed to embed WebWare in
>a DLL. This Dll serves multiple purposes: it exposes the object model of
>the application so that PSP scripts can call into it (done as a built-in
>Python extension module), it acts as an adapter redirecting the web server
>requests to the app server and it embeds a Python interpreter used to
>launch and control the WebWare app server.
