PHP Code Generation

[t.rakowski]

I'm trying to generate code from the following code Class Model

+ System
   + Test
       System_Test_Subclass
 System_Main

It almost works for me. The output I get is:

System/Test/System_Test_Subclass.php
System/System_Main.php

And the output I need is:

System/Test/Subclass.php
System/Main.php

Is there a way to change that so it works the way I need it ?
Is there an option or a file that controls the way it is all generated ?

Thanks,
