mapper.xml wanting more info

[GenesisRage]

would like to get more info on how to exactly make my own maps, ive worked on making maps for websites, but never had to deal with the ZoneRect, multi-levels (how they auto-change), or large multi-part maps. i know its a bit ambitious, but i would like to redo many of the maps, basically so they are all the same look (i like uniformity)... and gives me something to do when im bored, or waiting on that rare spawn

also mapper.xml is this REALLY needed, or is it just for extracting the /loc's?
if it is needed, where can i get it from, the site is currently down
