The program was written originally by

Lars Pensj|, April 1990 (lars@cd.chalmers.se).


Other credits:

The regexp package was made by Henry Spencer.

The ed package was not done by me. See the file ed.c for information.

Bit manipulations was implemented by pell@lysator.liu.se who also found
several bugs that had eluded me for months.

Valuable help and hints from: Mark Nagel, James Seidman, Moonchilde and more.

Mike McGaughey told me how important it was to collect the program for objects
in a sequential area. This reduced the working set for the game by 50 %.
He also implemented typeahead for players, guaranteed response time
and hashed object names. He also discovered numerous space leaks.

Roland Dunkerley III fixed for-loops, do-while and the operators ++ and --.

Sean T Barrett made smalloc.c.
