Managing edits to sys files across many projects & platforms

[tod]

What I would ideally like to see is something like Roland suggested where I can ask for project specific optimization and then I would be responsible for modifying a file that configures the library build. This file could be a .h,.cpp, .xml whatever is easiest for NB. The system build then causes a rebuild of the system libs using the custom file in my project and the new lib files would be built in the /lib directory of my project. The standard lib files would be left untouched. That way I have both the actual libs and a document that shows me what I modified. This all assumes that a simple XML file can configure 80% of the most common things developers need to change. I would think at this point we might be able to identify those. Although for most platforms the idea of runtime adaptability is very appealing, after my recent experience with the SBL2e, I would be leery of any approach that increases code size by even a little for the developer that doesn't need modified system files.
