Subject: Feature: Enable config.h, config.c, and config.cpp support in package generation.
X-Git-Tag: 0.5.6~41
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=106c18c32131e72632761f8482ef66cf722c5fd0;p=fll

Feature: Enable config.h, config.c, and config.cpp support in package generation.

There is a common practice of having a config.h for local build time changes to be applied.
Provide a skeleton structure for this by default when building the FLL packages.
These files will be empty.

The user need only populate these files as needed.
This could be done manually, but doing this by default effectively documents the proof of concept with a working/functional example.

Perform some minor cleanup as well.
