I think my previous answer was not complete. pyplusplus has 2 custom
code creators:
custom_t and custom_text_t. If you need to write some text, any text,
anywhere you
can create instances of those code creators and put them in a right
place within extension
module code creators tree.

Right now there is no easy way to do it. I don't understand why it could be
a problem in future. I am sure I miss something.
This method works fine for boost.date_time and TnFOX.
Any way, when you need it, you need it. There is a way to do what you want.
file_writers package contains class multiple_files_t. This class is responsible
for writing\splitting extension module to multiple files. If you need
fine grained
control you can always derive from this class and implement your
custom behaviour.

Please, check whether you work with latest CVS version or not. Few
days ago TnFOX
has problem that main function was too big. This class has been improved a lot.
It better splits extension modules to files and has mush clear implementation.

Thanks for trying. I hope you will publish your experience and may be
source code.
I could learn a lot from seeing how you use pyplusplus
