Ack, thanks for that! It was
debug.inc.sqf and
macros.inc.sqf originally, but I merged the two include files into one a while ago
I'll fix it when I move the last bits of the readme onto the
Core wiki.
I'm terrible at keeping my readme's consistent with code changes and most people don't point out these sort of things (and I imagine most people use the addon versions anyway, where there isn't a need to mess about so much).
