-    This entry confuses some C-preprocessors and some C-beautifiers.
-    We found one cpp that processed this source differently when

-    If you liked what you saw from the above program, and happen to

-## Author's comments
 
-    Description:
-	The following short program implements the "Yet Another" algorithm for
-	generating prime numbers.  It will generate all primes up to 33554432,
-	displaying them to the standard output as it churns along.  As 33554432
-	is rather large on most machines, this code may take quite some time to
-	run to completion, so as an added feature, it will cease execution upon
-	reception of a signal (any will do equally well), as well as in the
-	event of a system shutdown or reboot.
-	
-    Bugs:
-	The alternative version (weisberg.alt) has never actually run
-	to completion. After running for close to a week it had reached
-	somewhere around 250e6, when it became necessary to test the
-	reboot feature (which worked remarkably well) As there are
-	quite a lot of primes to be found before reaching MAXINT, the
-	output produced can be quite overwhelming, it recommended to
-	pipe the output through your favorite pager (more or less), and not 
-	output to a paper output device (unless you have *LOTS* of paper).
+## Judges' comments:
 
-    Technical:
-	The original "Yet Another Prime Program" algorithm used here was
-	developed as a Computer Architecture course micro-programing exercise,
-	and was designed to take full advantage of the UR300
-	micro-architecture to achieve blindingly fast speed. It was ported to
-	C specifically for the IOCCC. In the conversion/obfuscation step some
-	of (much of) the blazing speed was lost, but as a bonus, the
-	understandability of the code was reduced to zero.
