"""
 | 
						|
A simple bench runner which delegates to the ./dotest.py test driver to run the
 | 
						|
benchmarks defined in the list named 'benches'.
 | 
						|
 | 
						|
You need to hand edit 'benches' to modify/change the command lines passed to the
 | 
						|
test driver.
 | 
						|
 | 
						|
Use the following to get only the benchmark results in your terminal output:
 | 
						|
 | 
						|
    ./bench.py -e /Volumes/data/lldb/svn/regression/build/Debug/lldb -x '-F Driver::MainLoop()' 2>&1 | grep -P '^lldb.*benchmark:'
