+## Judges' comments
 
 	Run this with a single digit argument (or wait a long time).
 
-	There are 2 versions of this program, the one that was entered,
-	and one that was changed by the judges to be more portable. The
-	makefile runs the latter version by default.
-
 	The blank line at the beginning of the source is mandatory.
 	Do you know why?
 
-	The shell script run by the makefile joins lines that may be
-	cut up by mailers.  The file "fubar.orig.c", for example, needs
-	the 6th and 7th lines joined together (with a space between
-	them) to recreate the original entry.  If you fix the file, you
-	will need to change the last 8 linnes of "fubar.orig.sh" to read:
-
-		cp fubar.orig.c ouroboros.c
-		chmod +x ouroboros.c
-		csh ouroboros.c $1
-		rm -f ouroboros.c x1 x
-
-	The more portable version, "fubar.c", can be fixed by joining the
-	7th and 8th lines in the same way.  As well, if you fix "fubar.c"
-	you will need to also change the last 8 lines to "fubar.sh" to read:
-
-		cp fubar.c ouroboros.c
-		chmod +x ouroboros.c
-		csh ouroboros.c $1
-		rm -f ouroboros.c x1 x
