To apply this patch make sure PATCH.COM and DOOM.EXE are present in the
directory, and type the following:

   patch doom.exe doom-p.exe

A new executable (DOOM-P.EXE) will appear. Place it in your DOOM (or
DOOM II) directory to play levels that exceed Doom's standard limits.

This patch produces the same binary offered in the 6th Doom-plus release
by e6y. The changes implemented are the following:

-------------------------------------------------------
limit                         : old    * k   = new
-------------------------------------------------------
visplanes[MAXVISPLANES]       : 128    * 8   = 1024
drawsegs[MAXDRAWSEGS]         : 256    * 8   = 2048
SAVEGAMESIZE                  : 180224 * 16  = 2883584
activeplats[MAXPLATS]         : 30     * 256 = 7680
vissprites[MAXVISSPRITE]      : 128    * 8   = 1024
linespeciallist[MAXLINEANIMS] : 64     * 256 = 16384
openings[MAXOPENINGS]         : 16384  * 4   = 65536
