------------------------------------- D! 2.0 beta (build 06) upgrade patch. ------------------------------------- This patch will upgrade D! version 1.5 to the new D! 2.0 public beta (build 06). If you do not have D! 1.5, this will install a public beta of the D! 2.0 DEMO version (some slight crippling of the features). D! - The ultimate front-end for DOOM, Ultimate DOOM, DOOM 2, and HERETIC. Nothing else, even comes close.
