+MAMEBench
+=========
+This is a set of shell scripts which make it simple to run parallel benchmarks on all roms in a directory.
+
+Usage: ./mamebench.sh <romdir> <benchfile> [-t <benchtime>] [-j <threads>] [-p <pattern>]
+
+
+Examples:
+
+# Benchmark all roms in /data/roms for 45 seconds each, using 4 threads
+$ ./mamebench.sh /data/roms benchmark-20150519.tsv -t 45 -j 4
+
+# Benchmark all sf2 variants in /data/roms for 90 seconds each, using 6 threads
+$ ./mamebench.sh /data/roms benchmark-20150519.tsv -t 90 -j 6 -p sf2*
