To give youa feeling for the accuracy of these numbers, it comesout something like this:  If you were to measure thedistance from Los Angeles to New York to this accuracy,it would be exact to the thickness of a human hair.That's how delicately quantum electrodynamics has, in thepast fifty years, been checked -- both theoretically andexperimentally.EOFdiff snefru256Output correctSnefru256Outputif [ $? -eq 0 ] ;  then	/bin/echo Test Passedelse	/bin/echo Test Failedfi
