The '*' lines contain comments.  The 'S' line is the last line of the section.

Every other command contains four numbers (three for the 'G' command).  The first number is ignored.  The next three (or two) numbers are interpreted as follows:

For the 'M' command, the second number is the vnum of a mobile to load.  The third number 
is the limit of how many of this mobile may be present in the world.  The fourth number is the 
vnum of the room where the mobile is loaded.

For the 'O', 'P', 'G', and 'E' commands, the second number is the vnum of an object to load.  
The third number is ignored.

For the 'O' command, the fourth number is the vnum of the room where the object is loaded.  
The object is not loaded if the target room already contains any objects with this vnum.  The 
object is also not loaded if any players are present in the area.

For the 'P' command, the fourth number is the vnum of a container object where the object 
will be loaded.  The actual container used is the most recently loaded object with the right 
vnum; for best results, there should be only one such container in the world.  The object is 
not loaded if no container object exists, or if someone is carrying it, or if it already contains 
one of the to-be-loaded object.

For the 'G' command, there is no fourth number.  If the most recent 'M' command succeeded 
(e.g. the mobile limit wasn't exceeded), the object is given to that mobile.  If the most recent 
'M' command failed (due to hitting mobile limit), then the object is not loaded.

For the 'E' command, the fourth number is an equipment location.  If the most recent 'M' 
command succeeded, that mobile is equipped with the object.  If the most recent 'M' 
command failed, then the object is not loaded.

For the 'D' command, the second number is the vnum of a room.  The third number is a 
door number from 0 to 5.  The fourth number indicates how to set the door: 0 for open 
and unlocked; 1 for closed and unlocked; 2 for closed and locked.

For the 'R' command, the second number is the vnum of a room.  The third number is a 
door number.  When this command, the doors from 0 to the indicated door number are 
shuffled.  The room will still have the same exits leading to the same other rooms as before, 
but the directions will be different.  Thus, a door number of 4 makes a two-dimensional 
maze room; a door number of 6 makes a three-dimensional maze room.

Use of both the 'D' and 'R' commands on the same room will yield unpredicatable results.

Any line (except an 'S' line) may have a comment at the end.
