Yes I had noticed it is a large package. Is the number of files in the libbsd.py
module the concern? There is a point of view that says explicit listing of files
is better because you do not accidentally pick up files you should not where
glob'ing a tree in builder.py or libbsd.py could do that.
The include lists in builder.py was something I knew would come back and bite
me. There was only so much I could do at the time and this fell of the end. I
thought the list might grow but could not see a real use case. I can fix this
once the patch is merged.

Not at the moment. Lets get this work in and then I can take a look. It will be
simpler and also clearer to see what is happening.
I could look at making libbsd.py into libbsd/__init__.py with a file per module
and the top level just sees the imports. I still see no need for us to have
module build control, we always build all modules.
