Why do you think this is the case? It's not. If a transformer creates 
code that requires a particular header, it has to declare so by calling 
the require_header() method on the corresponding code manager object.

Could you provide an explanation using the following example scenario:

A user implements a custom code creator in his generation script. The 
code creator can be parameterized and can produce slightly different 
code depending on those parameters. Each code variation has its own set 
of required header files, some of which are written by the user, some 
are part of the project he's creating wrappers for and some might be 
from the Py++ code repository.
After the Py++ code creator tree has been built, the user adds several 
of his custom creators at appropriate places into the tree.

Now the question is, what else has to be done to include the required 
header files and who's actually including them? And where do the 
decl_wrapper classes come into play here?
