EventScripts

EventScripts is a free game scripting plugin for Valve Corporation's Source engine. Aimed at first-time scripters, EventScripts has grown to be one of the most popular Source scripting engines, running on over 8700 dedicated game servers worldwide as of June 2007. 1

Overview

As of version 1.5, the scripting engine of EventScripts is not unlike a command-line shell (like bash) built on top of the Source engine's console. It was designed to be simple to use for administrators since experienced coders have access to creating Source plugins via Valve's Source SDK in C++.
