test_description="Comparison of git-grep's regex engines
 | 
						|
 | 
						|
Set GIT_PERF_7820_GREP_OPTS in the environment to pass options to
 | 
						|
git-grep. Make sure to include a leading space,
 | 
						|
e.g. GIT_PERF_7820_GREP_OPTS=' -i'. Some options to try:
 | 
						|
 | 
						|
	-i
 | 
						|
	-w
 | 
						|
	-v
 | 
						|
	-vi
 | 
						|
	-vw
 | 
						|
	-viw
 | 
						|
 | 
						|
If GIT_PERF_GREP_THREADS is set to a list of threads (e.g. '1 4 8'
 | 
						|
etc.) we will test the patterns under those numbers of threads.
