The script ./bench.sh <directory> <options...> uses faust2bench to measure the performances of the .dsp files of the folder dsp/ according to various compilation options.
For example ./bench.sh test1dir -lang cpp compiles all the files of dsp/ using the options -lang cpp and places the resulting binaries into the folder test1dir. Then it runs all the binaries of test1dir.
The binaries can be re-executed (without recompilation) using the command ./run.sh test1dir.
