| 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. |
