Other options: --benchmark test search performance --benchmark-single test search performance --benchmark-more arg (=0) number of problems for benchmark --sleep-at-exit arg (=0) seconds of sleeping at exit --health-check test whether data files are properly placed -h [ --help ] produce help message -v [ --verbose ] produce verbose output --version show version info
