Best self-modifying program: <sequent!fubar> Jay Vosburgh	Jay Vosburgh        Sequent Computer Systems, Inc        15450 SW Koll Parkway        Beaverton, OR        97006        USAJudges notes:	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 xSelected notes from the author:	In a nutshell, this is probably the slowest and most	obnoxious factorial program ever written.  Unfortunately, 	the name of the C source must be "ouroboros.c"; the name is 	hard-coded into the program.  	The source is a legal shell script and a legal C program.  	The shell script compiles itself, and then executes the	resulting binary, giving the source as input.  The program 	works by successively modifying #define lines each pass through.	Both "indent" and "cb" will damage the program, "indent" 	much more so.
