This is the options Quick Reference

Note: the options BLIND and SAFE has changed syntax since v1.1.

<Distance> The distance is the number of sectors between two sectors
   Counted in a strange way. For instance if you want the monsters in
   a sector to be totally blind use 'BLIND <Sector> 0'. If you want them
   to be able to see their own sector use 'BLIND <Sector> 1',
   for neighbours use 2 and so on.

<Euclidian distance> is the distance in 1/10 th of meters (intuitively)
   that monsters can see.

<Line no> Is the number of a TWO SIDED line. This line number can be found
   using almost every WAD builder. (DEU5.21 recommended)

<Sector> is the number of a sector. can also be found
   by the same WAD builder.

<Sector list> Is a list of sector numbers terminated by end of line
   example: 1 2 5 7 9 
   Is a list of the sectors 1, 2, 5, 7 and 9.

a brief explanation: (sorted alphabetically)

*  BLIND     Specifies the distance a monster can see (near sighted)
   BLOCK     Monsters can't look through BOTH 2s lines (One is ok)
   DISTANCE  The maximum distance a monster can see.
   EXC       Excludes view from 1st sector to 2nd. (Overrides all other opt)
   INC       Includes LOS from 1st sector to 2nd. (Overrides all other opt)
*  INV BLIND Specifies that monsters can only see outside the distance.
*  INV SAFE  Monsters can't see this sector(s) inside the distance.
   LEFT      Makes a 2s line that can only be looked through left to right.
   LENGTH    Specifies the max # of sectors any monster can see.
   LINE      Makes a 2s line impossible to look through for monsters.
   NOMAP     Removes the graphical look, and prints only ASCII
   ONE       Same as block, but only stops LOS one way.
   PERFECT   Generates a perfect reject map.
   REPORT    Reports all detected distances >=<distance> to <wad file>.RPT
   RIGHT     Makes a 2s line that can only be looked through right to left.
*  SAFE      Monsters can't see this sector(s) outside the distance.

Options marked by * indicates that BLIND and SAFE gets
special meanings when combined with INV BLIND and INV SAFE (respectively)
for the same sector.
