This is currently maintained by Mouse, . The original version bore a copyright license I no longer have an exact copy of. See the paragraph before my signature, below; I am including the license mentioned there because I believe this is required, even though it is quite out of date - see the embedded note I wrote in February 1993. Any intellectual property interest I (Mouse) may have in this work I hereby explicitly release into the public domain (meaning, in particular, that my claim of copyright quoted below is no longer accurate). In jurisdictions where this is not possible, I instead intend the closest available approximation, probably something like "you have an unlimited, perpetual, sublicensable right to use (the affected intellectual property) in any way you see fit". All of this is, of course, subject, for portions that are derived works within the meaning of applicable law, to the below-quoted license for the base work. Everything after the following signature (ie, the stuff beginning "Copyright 1989...") is the copyright notice I found in my copy. It is my modification, presumably in 1993, of the original, apparently done without taking care to obey clause 1. I have not attempted to undo my modifications, on the grounds that piling changes on changes only muddies the waters further; to the best of my current recollection, my changes include only the "Portions copyright..." sentence at the top, the parenthesis in clause 2 (which was badly worded; I intended to indicate that I did not request copies of changes, not that I (believed I) had no need to obey clause 2), and the note after clause 5. -- Mouse, , 2009-03-28. Wording slightly touched up 2011-01-29; no substantive changes. Copyright 1989, 1990 by David Applegate, James Aspnes, Timothy Freeman, Bennet Yee, and Na Choon Piaw (lachesis).

Note by der Mouse, February 1993: this appears to be out of date. What contact info I have been able to obtain places Bennet Yee at bsy+@cs.cmu.edu, James Aspnes at asp+@cs.cmu.edu, Timothy Freeman at tsf+@cs.cmu.edu, and David Applegate at david@research.att.com. I have no contact info for Na Choon Piaw. I have exchanged mail with Bennet Yee, and in <9302232147.AA08197@Lightning.McRCIM.McGill.EDU>, dated "Tue, 23 Feb 93 16:46:52 EST", was told "I don't have any interest in picking up changes now -- haven't played in years and am not even in contact with anybody actively playing these days.". I have also exchanged mail with David Applegate, and in <9302232333.AA09444@Lightning.McRCIM.McGill.EDU>, dated "Tue, 23 Feb 93 18:29 EST", was told "I don't care about changes, either. I would appreciate it if a note was added indicating that I don't want the changes.". The other email addresses are completely unverified; Howard, apparently the current DaemonMUCK maintainer, tells me that none of them are interested in changes any longer, something I have not been able to check except as listed above.
