+# Simple benchmark for Capstone by disassembling random code. By Nguyen Anh Quynh, 2014
+# Syntax:
+# ./suite/benchmark.py --> Benchmark all archs
+# ./suite/benchmark.py x86 --> Benchmark all X86 (all 16bit, 32bit, 64bit)
+# ./suite/benchmark.py x86-32 --> Benchmark X86-32 arch only
+# ./suite/benchmark.py arm --> Benchmark all ARM (arm, thumb)
+# ./suite/benchmark.py aarch64 --> Benchmark ARM-64
+# ./suite/benchmark.py mips --> Benchmark all Mips (32bit, 64bit)
+# ./suite/benchmark.py ppc --> Benchmark PPC
