+ I see sumone may be making a GUI program to help make maps...so if that happens and if it is ok I will provide a url to that program via my site as well...of course it all depends on the creator of that software...
If I do get around to actually writing it, you'll almost certainly be welcome to redistribute it. It'll probably end up GPL anyway - I'm using flex and bison to parse the map files (Probably overkill, but I have to learn them anyway. Also, I've already written a flex token-definition file for them).
