PURPOSE
L2BABYLON supports custom feature delivery through ext.jar where the module has been prepared for plugin loading.
USE CASES
A custom system such as an Auction House or another isolated extension can be packaged separately when supported by the current source.
INSTALLATION
1. Stop GameServer.
2. Back up the current ext.jar.
3. Copy the new ext.jar to the configured extension/library location used by the project.
4. Keep any matching config/data files in their required server directories.
5. Start GameServer and inspect the console for module-loading errors.
IMPORTANT
A jar alone is not enough when the module also requires HTML, XML, SQL, spawn or config files. Always install the complete patch for that module.
