Project main page (with Wiki links and description): http://dev.bukkit.org/server-mods/commandsex
This page is simply a proof-of-concept for a modular CraftBukkit plugin creation.
It uses built-in PHP functions to build a Java JAR file crafted per request, containing only the functions that you choose.
Usage: simply tick all the checkboxes next to commands you want to have in your CommandsEX build and click the "Generate" button at the end of page!
