I'm maintaining this here now because I need it to continue working for current cube games. And others should be able reap the benefits of that too.

Cube Server Lister is an application to monitor Cubeengine based game servers, like Cube, AssaultCube, Sauerbraten, Red Eclipse, and Blood Frontier. The goal of this project is to provide a fast and useful cross-platform server monitor.

Currently it provides the basic functionality like update from masterserver, listing servers, and join servers directly. Furthermore it supports some useful features like chat / server filtering, playtime statistics and map previews.
