	Umm. I now have a database whose md5sum i have verified, and I
 also have a md5sum binary I am sure of (since it is on the floppy
 with the keys and all); I verify md5sum and tripwire on my machine;
 run this known good tripwire and md5sum to test and see if this
 system has changed or not. 

	What am I missing here? What is the hard part?

The Gurus of Unix Meeting of Minds (GUMM) takes place Wednesday, April
1, 2076 (check THAT in your perpetual calendar program), 14 feet above
the ground directly in front of the Milpitas Gumps.  Members will grep
each other by the hand (after intro), yacc a lot, smoke filtered
chroots in pipes, chown with forks, use the wc (unless uuclean), fseek
nice zombie processes, strip, and sleep, but not, we hope, od.  Three
days will be devoted to discussion of the ramifications of whodo.  Two
seconds have been allotted for a complete rundown of all the user-
friendly features of Unix.  Seminars include "Everything You Know is
Wrong", led by Tom Kempson, "Batman or Cat:man?" led by Richie Dennis
"cc C?  Si!  Si!" led by Kerwin Bernighan, and "Document Unix, Are You
Kidding?" led by Jan Yeats.  No Reader Service No. is necessary
because all GUGUs (Gurus of Unix Group of Users) already know
everything we could tell them.  -- "Get GUMMed," Dr. Dobb's Journal,
