1991 marked the "The Eighth International Obfuscated C Code Contest"Copyright (c) 1991, Landon Curt Noll & Larry Bassel.All Rights Reserved.  Permission for personal, education or non-profit use isgranted provided this this copyright and notice are included in its entiretyand remains unaltered.  All other uses must receive prior permission in writingfrom both Landon Curt Noll and Larry Bassel.Instructions for use: Run make to compile entries.  It is possible thaton BSD or non-unix systems the makefile needs to be changed.Look at the source and try to figure out what the programs do, and runthem with various inputs.  If you want to, look at the hints files for(minor) spoilers.This year, we did not single out an entry that was better than all ofthe rest.  We selected 3 entries that were, in our opinion, went beyond all of the other entries this year:	Grand Prize			by Brian Westley	Most Well Rounded		by Diomidis Spinellis	Best Of Show    		by Daniel J. BernsteinName and address information are separated from the actual programprior to judging.  This eliminates any chance that we would bias ourjudging for/against any person or group.  In the end, we are surprisedas you are to see who as won.  Even so, it is worth noting thatBrian Westley has submitted a winning entry for the past 5 years!A few notes regarding possible changes to the contest:We did not give awards to some traditional contest categories such as"Best Layout" or "Worst Abuse of the Rules".  We felt that to do sowould deny awards to more deserving entries.  These categories have notbeen eliminated, and will likely be considered in future years.A number of entries made use of the following C pre-processor feature:	#define X define	#X foo barThis is not permitted under ANSI C.  Some ANSI C compilers do allowthis.  In the future, we do not want programs to use this feature.Because this request was not stated in the 1991 rules, we did notreject entries of this type.  However we provided more portableversions so that more people could compile these programs.This year we received entries that made use of the X Window System.This functionality is now available on many systems, we feel that programs that use these are now portable enough to be valid entries.  We may allow programs to make use of the X Window System libs and include files, provided that they can operate with a system running at the level of at least X11r4.  Requiring the use of imake, a specific window manager,specific display hardware, or a specific user interface (Openl**k, M*tif, ...) is likely not to be allowed.  We will provide a more detailed explanation of our viewpoint in next year's rules.In order to encourage more 'normal' looking C programs, we are considering the following change to the maximum size rule:    Your source, not counting any <space>, <tab>, and a <newline> character,    and not counting any ';', '{' and '}' character followed by a <newline>    character, must be 1536 bytes or less.  The entire source, counting all    characters, be 4096 bytes or less.Some thought has been given to adding some c++ categories, however thisis not likely to happen soon.  We are waiting until c++ compilers becomecommon place on a wide number of systems.  We also need time to braceourselves for what obfuscation c++ could wield!Be sure to wait until the 1992 rules are posted before submitting entries.  We may fine tune the rules to reflect the some ideas above.Please send us comments and suggestions what we have expressed above.Also include anything else that you would like to see in future contests.Send such email to:	...!{sun,pacbell,uunet,pyramid}!hoptoad!judges	judges@toad.comCredits:We would like to thank Barbara Frezza for her role as official chef of the contest.  Landon Noll appreciated the opportunity to serveas assistant pizza chef.  Larry Bassel was official taste tester. Yummo!
