This is an independent reimplementation of the DOOM
engine. It shares no code with id Software's release. The game data it
loads is Freedoom, a free and open replacement asset
set distributed under a BSD licence — not id's DOOM, whose
data this project neither contains nor requires.

It is a personal project, unaffiliated with the author's employer, and nothing here represents anyone's views but the author's.
