*** REPLACE THIS LINE WITH YOUR LIFE HISTORY ***

After grabbing the bgrep distribution off of mod.sources recently
I decided to try a quick test of the various grep's on one our system
V release 2 ports:

	Trial 1:	*grep FOOBARBLETCH /etc/termcap
	Trial 2:	*grep BARF /etc/termcap
	Trial 3:	*grep MI /etc/termcap
	
	/etc/termcap approx 50kb
	
	
		trial 1			trial 2			trial 3
	real	user	sys	real	user	sys	real	user	sys
	----	----	---	----	----	---	----	----	---

grep	1.9	1.1	0.6	1.8	1.1	0.6	1.8	1.1	0.6
bgrep	2.7	1.9	0.7	2.3	1.4	0.7	4.9	3.9	0.7
egrep	3.5	2.6	0.7	3.6	2.8	0.6	3.5	2.7	0.6
fgrep	9.6	8.8	0.7	9.7	9.0	0.6	9.8	8.9	0.7


Notice that plain old grep is the fastest of all, and fgrep is the slowest!
