That is actually a good question Sheldon, I wish I had the answer.
That is one area that I think the folks that make the PBP compiler could help out. I think that is one area where the Arduino community shines. They are able to share "Libraries" with each other. Now granted the Arduino is limited to just a few versions so there is not a lot of variety to adapt the libraries to. Where as the literally dozens of PIC's with each of their different pin assignments, PWM, comparators, etc. presents much more of a challenge to the concept of "modules" or "libraries".

Someone more knowledgeable than me might jump in here to give some guidance.

I do think that is an area that the PBP folks could help the users learn how to at least do easier and understand better the use of include files.

I know that Darrell Taylor and others have mastered the concept of "Include" files.

I really think Melabs could make an effort to keep this excellent PBP compiler community alive and vibrant and growing (and to attract some of the other microcontroller users over to the PBP compiler.)
