# Parametrisation to this script is as follows:
# * The first argument will be taken as suffix to the result folder
#   e.g. `./bench.sh _config0`
# * It is possible to make its output a bit more verbose by setting
#   the `VERBOSE` environment variable to '1', e.g. via
#   `VERBOSE=1 ./bench.sh` or to make it quiet by setting it to '0'
# * Per default we read from /dev/ttyUSB2, by setting the `WC_TTY`
#   environment variable this can adapted
#   e.g. `WC_TTY=/dev/ttyACM0 ./bench.sh`
