zdbsp - 1.19+20181027+dfsg.1-2+b1 main

zdbsp is a node builder specially designed to be used with OpenGL ports of
the DOOM game engine. It adheres to the "GL-Friendly Nodes" specification,
which means it adds some new special nodes to a WAD file that makes it very
easy (and fast!) for an OpenGL DOOM engine to compute the polygons needed
for drawing the levels.
