Ok! I'll continue to give this a shot

Includes.

I guess we need acknex.h for doing anything at all.
But what about mtlfx.c? Do its lines/size count, or are they "free"?

Anything that comes with a default installation of GS is "free".

Lets say I've written a script interpreter, do the scripts it interprets count against the limit?

All the code (including the scripts) is counted.

Out of curiosity (I'm not participating since I already have A8 Pro and enough work to do, but I really like the look of this contest), what if the scripts are not included, but are instead read from a server using the http_ functions?

EDIT: A program that interprets and executes scripts could well be a contender for those qualities alone, as long as it's judged as such and not by the actual game(s) scripts demonstrating it.

All the contest entries must run without needing an internet connection, so reading a script from a server is not encouraged. On the other hand, an interpreter would be a nice contest idea, provided that it and its examples obey the 5KB rule.

www-wait, the examples must be under 5KB,too?

I guess then I am out.

I thought the example that uses the 5kb script was not counted?

i am writing some snippet(s) and a demo that show how to use it. if demo is counted , then im also out too.

Well, in this case I'm out of the contest too =/
What a shame.
