ZDBSP  is  a nodes builder specially designed to be used with OpenGL-based DOOM game engines.  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 for an OpenGL DOOM engine to compute the polygons needed for drawing the levels.
