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