What
preprocessor do you use then, M4? I'm curious to find out how you use an
external preprocessor. In principle it's not a bad idea to use an
external one. I suggest we could also make it a bit more user friendly
by providing some hooks in fpmake. This way one should not nescesarily
create additional scripts to copy files to other locations. What do you
think?

Please demonstrate how you use macro's in your perticular case.
How do you adjust your build system.
