Well this is my first attempt at fighting the Spider Demon on Nitemare
mode and to me it looks like a pretty good FIRST try!

  This LMP requires that you have Doom 1.5b w/1.2 REGISTERED wad AND 151.wad.
to do this all you need to do is copy your 1.2 registered wad to the same
directory as your 1.5b EXE.  If that is too hard to comprehend here's an
example:

  Say you registered Doom version 1.2 and recently downloaded Doom 1.5b (the
shareware only version).  You feel like you wanna play Doom 1.5 REGISTERED so
you copy the doom.wad from 1.2 into the 1.5 directory.  In order to get this
to work...oh hell!  If you don't understand this then give up DOOM(tm) and 
play Blake Stone a nice little game from Apogee.

  Just make sure you have 15regwad.zip from infant2.sphs.indiana.edu (where
you got this from)

  If you don't know DOS then just type "spider" from the directory that your
Doom 1.5b w/151.wad and Reg 1.2 doom.wad and hit ENTER (duh!)!  

  If you happen to be one of those gifted people who know DOS then run doom
loading 151.wad (came with 15regwad.zip) and playdemo spider...

  I'm not even gonna bother putting my name on this...Not like anybody's 
reading this :)  You can do whatever the hell you want to do with this lmp!
I don't care!  Mutilate it all you want!  I DON'T CARE!  I was so bored 
that I made spider.bat longer then the whole demo!  

  last second update...I've included the 15regwad.zip with this, and I'm too 
lazy to re-write this :) 

  Uh...Oh yeah!  I'd like to thank the little people who helped make this
possible (Namly, iD), And my mother, father, brother, sister (in law), uncle,
cousins, 2nd cousins, great grandma, grandpa, the other grandma, what's her 
name, uh...Dog's, Chinchilla (No, not a small DOG!), fish (one of them is 13
years old!  And he's a $.25 goldfish!)...who else....<Your Name Here> (for 
actually reading this whole thing!)
