[LLat. obfuscare, to darken : ob(intensive) +		Lat. fuscare, to darken < fuscus, dark.] -obfuscation n.		obfuscatory adj.GOALS OF THE CONTEST:    * To write the most Obscure/Obfuscated C program under the rules below.    * To show the importance of programming style, in an ironic way.    * To stress C compilers with unusual code.    * To illustrate some of the subtleties of the C language.    * To provide a safe forum for poor C code.  :-)NOTE: Changes from the 1993 draft are noted by change bars.  --->	      |RULES:    To help us with the volume of entries, we ask that you follow these rules:    1) Your entry must be a complete program.    2) Your entry must be <= 3217 bytes in length.  The number of characters       excluding whitespace (tab, space, newline), and excluding any ; { or }       followed by either whitespace or end of file, must be <= 1536.    3) Your entry must be submitted in the following format:---entry---rule:	1993fix:	y or n   (n => this is a new entry, y => this replaces an older entry)title:	title of entry  		    (see comments below)entry:	Entry number from 0 to 7 inclusive  (your 1st entry should by 0)date:	Date/time of submission in UTC	    (see comments below)host:	Machine(s) and OS(s) under which your entry was tested	Use tab indented lines if needed---remark---    Place remarks about this entry in this section.  It would be helpful if    you were to indent your remarks with 4 spaces, though it is not a    requirement.  Also, if possible, try to avoid going beyond the 79th    column.  Blank lines are permitted.---author---name:	your nameorg:	School/Company/Organizationaddr:	postal address	use tab indented lines to continue	don't forget to include the countryemail:  Email address from a well known site or registered domain.        If you give several forms, list them on separate tab indented lines.anon:	y or n   (y => remain anonymous, n => ok to publish this info)---info---If your program needs an info file, place a uuencoded copy of it inthis section.  In the case of multiple info files, use multiple infosections.  If your entry does not need a info file, skip this section.---build---Place a uuencoded copy of the command(s) used to compile/build your programin this section.  It must uudecode into a file named 'build'.  The resultingfile must be 255 bytes or less.---program---Place a uuencoded copy of your program in this section.  It must uudecodeinto a file named is 'prog.c'.  The resulting file must follow rule #2.---end---      Regarding the above format:	* The title must match the expression: [a-zA-Z0-9_=][a-zA-Z0-9_=+-]*	  and must be 1 to 12 characters in length.	  It is suggested, but not required, that the title should	  incorporate your username; in the case of multiple authors,	  consider using parts of the usernames of the authors.	* The date in the ---entry--- section should be given with respect	  to UTC.  The format of the date should be as returned by asctime()	  using the C locale.  (see guidelines for more info)	* You may correct/revise a previously submitted entry by sending	  it to the contest email address.  Be sure to set 'fix' in the	  ---entry--- section to 'n'.  The corrected entry must use the same	  title and entry number as submittion that is being corrected.  Be	  sure that you note the resubmittion in the ---remark--- as well.	* With the exception of the header, all text outside of the above	  format may be ignored by the judges.  If you need tell the judges	  something, put it in the ---remark--- section, or send a separate	  Email message to the judges.	* Information from the ---author--- section will be published unless	  'y' was given to the respective author's 'anon' line.	* To credit multiple authors, include an ---author--- section for	  each author.  Each should start with ---author--- line, and	  should be found between the ---entry--- and ---build--- sections.	* The entry's remarks should include:	    - what this program does	    - how to run the program (sample args or input)	    - special compile or execution instructions, if any	    - special filename requirements (see rule 4 and 5)	    - information about any ---data--- files	    - why you think the program is obfuscated	    - note if this entry is a re-submission of a previous entry.	    - any other remarks (humorous or otherwise)	* Do not rot13 your entry's remarks.  You may suggest that certain	  portions of your remarks be rot13ed if your entry wins an award.        * Info files should be used only to supplement your entry.  They	  should not be required to exist.	  If your entry does not need an info file, skip the ---info---	  section.  If your entry needs multiple info files, use multiple	  ---info--- sections, one per info file.  You should describe	  each info file in the ---remark--- section.    4) If your entry is selected as a winner, it will be modified as follows:	   'build' is incorporated into a makefile, and 'build' is removed	   'prog.c' is renamed to your entry's title, followed by an optional	       digit, followed by '.c'	   your entry is compiled into a file with the name of your entry's	       title, possibly followed by a digit       If your entry requires that a build file exist, state so in your       entry's remark section.  The makefile will be arranged to execute a       build shell script containing the 'build' information.  The name of       this build shell script will be your entry's title, possibly followed       by a digit, followed by '.sh'.       If needed, your entry's remarks should indicate how your entry must       be changed in order to deal with the new filenames.    5) The build file, the source and the resulting executable should be       treated as read-only files.  If your entry needs to modify these files,       it should make and modify a copy of the appropriate file.  If this       occurs, state so in your entry's remarks.    6) Entries that cannot be compiled by an ANSI C compiler will be rejected.       Use of common C (K&R + extensions) is permitted, as long as it does not       cause compile errors for ANSI C compilers.    7) The program must be of original work.  All programs must be in the       public domain.  All copyrighted programs will be rejected.    8) Entries must be received prior to 07-May-93 0:00 UTC.  (UTC is       essentially equivalent to Greenwich Mean Time)  Email your entries to:		...!{apple,pyramid,sun,uunet}!hoptoad!obfuscate		obfuscate@toad.com       We request that your message use the subject 'ioccc entry'.       If possible, we request that you hold off on Emailing your entries       until 1-Mar-93 0:00 UTC.  Early entries will be accepted, however.       We will attempt to email a confirmation to the the first author for       all entries received after 1-Mar-93 0:00 UTC.    9) Each person may submit up to 8 entries per contest year.  Each entry       must be sent in a separate Email letter.   10) Entries requiring human interaction to be built are not allowed.       Compiling an entry (must) produce a file (or files) which may 	      |       be executed.							      |   11) Programs that require special privileges (setuid, setgid, super-user,       special owner or group) are not allowed.FOR MORE INFORMATION:    The Judging will be done by Landon Noll and Larry Bassel.
