#    RunBenchmarks.sh
#    
#    This is a sample script for how to run benchmarks on Unix-like system.
#    
#    It requires the user to set CORECLR_ROOT to the root directory
#    of the enlistment(repo).  It also requires that CoreCLR has been built, 
#    and that all CoreCLR tests have been built.
#    
#    The preformance harness "RunBenchmarks.exe" is built as a test case
#    as are all the performance tests it runs.
#    
#    For the ByteMark tests, it must copy the command scripts to the 
#    binary directory for the tests.
#
#    By default, the performance harness is run on top of CoreCLR.  There
#    is a commented out section that can be used to run on top of DesktopCLR.
#    
#    A standard benchmark run is done with one warmup run, and five iterations
#    of the benchmark.
