[C++-sig] Problem with current pyste and inheritance

[Gideon May]

Hi,

I've got a C++ class hierarchy which looks like this:

Base
  ^
  |
Derived
  ^
  |
Sub

and I want to use pyste to generate python bindings.
I've got it working except for the fact that the bindings
for Derived are being defined twice by pyste.
I've attached the include files and pyste files. I generate
the code with the following command:
  pyste --module=double Base.pyste Derived.pyste Sub.pyste

Any suggestions ?

Thanks,

Gideon
