Qrucible

Contents
Qrucible is a utility targeted at the original trilogy of Quake games from id Software. It provides a friendly compiler front end to make map compilation simple, but it also offers a robust Plugin (via Python) and Prefab (via .MAP files) system to make the act of constructing maps easier and faster.
All is explained below in the documentation so have a look around and hopefully you can find a spot for Qrucible in your mapping workflow.
