L2J Server

Who can give a link to the documentation for the core and datapak l2j

http://www.l2jserver.com/wiki/L2j_Wiki:Community_Portal

Unfortunately, there's no really complete & detailed documentation for L2J out there.
So most likely, you'll have to familiarize yourself with it by reading core-code (and the comments inside it), dp-scripts, xml's, browsing through the database and so on...

thats a javadoc smartass, not a documentation.
