Err.. Mark means from within Python. That's not to say you can't build a
type library using an IDL file and MIDL.

Here's an example for the Python.Interperter COM server that exists in
win32com\servers\interp.py.

Unfortuantely, Python.Interpreter needs a slight change inorder to write an
IDL file.
Replace the  _public_methods_ line with:
	_dispid_to_func = { 1 : Eval, 2 : Exec }
A matching IDL that should work is attached below:
(As an added bonus, this should actually work)
The only GUID from interp.py is the coclass one. Every other GUID was just
generated.
Hope the below helps.... The MIDL docs in MSDN are certainly less than
useful. :(

// System idl include nonsense
import "oaidl.idl";
import "ocidl.idl";

dispinterface IPythonInterpreter
{ properties: 
methods:
	[id(1)] HRESULT Eval([in] BSTR bstrExpression, [out, retval] VARIANT
pvarReturnValue);
	[id(2)] HRESULT Exec([in] BSTR bstrExpression);
};

	coclass PythonInterpreter

		[default] dispinterface IPythonInterpreter;
	};
