.pyd is just a naming convention. It was probably introduced to prevent
name clashes with unrelated DLLs.

I think you can configure the output file name in the project properties.

Assuming your module is called _cmd:
- add a function init_cmd_d to the extension module (init_cmd_d simply
- import cmd_d in your Python script
I must admit I haven't tried this, it is based on my understanding of
how Python loads extension modules.
