"Welcome to dunnet (2.01), by Ron Schnell (ronnie@driver-aces.com).
Here is some useful information (read carefully because there are one
or more clues in here):
- If you have a key that can open a door, you do not need to explicitly
  open it.  You may just use 'in' or walk in the direction of the door.

- If you have a lamp, it is always lit.

- You will not get any points until you manage to get treasures to a certain
  place.  Simply finding the treasures is not good enough.  There is more
  than one way to get a treasure to the special place.  It is also
  important that the objects get to the special place *unharmed* and
  *untarnished*.  You can tell if you have successfully transported the
  object by looking at your score, as it changes immediately.  Note that
  an object can become harmed even after you have received points for it.
  If this happens, your score will decrease, and in many cases you can never
  get credit for it again.

- You can save your game with the 'save' command, and use restore it
  with the 'restore' command.

- There are no limits on lengths of object names.

- Directions are: north,south,east,west,northeast,southeast,northwest,
                  southwest,up,down,in,out.

- These can be abbreviated: n,s,e,w,ne,se,nw,sw,u,d,in,out.

- If you go down a hole in the floor without an aid such as a ladder,
  you probably won't be able to get back up the way you came, if at all.

- To run this game in batch mode (no Emacs window), use:
     emacs -batch -l dunnet
NOTE: This game *should* be run in batch mode!
