This is an application framework called "ggl" or GunGame League.
It's based directly from GunGame AMXX 2.00B3
The framework is nearly finished but I don't have the motivation to finish it. Last time I played with it, there was a funky bug within the menumanager.
The framework provides the following functionality:
Application Domain - using SID verification
Security using a GUID and SID (global unique id and session id)
Menu wrapper.
Messaging system with Priority Queues HML
SQL Priority Queue Pumps: High, Medium, Low
HTTP reader/writer - interfaces the application with ggl.php on a webserver
There is absolutley NO SUPPORT for this and I offer absolutley NO GUARANTEE that it wont completley destroy your server(s) I am posting it because I feel it has some sort of value and I don't have the motivation to continue working on it.
