pipenv run python example.py --help
usage: example.py [options]
We have some defaults depending on --mode. {'square': {'amplitude': 0.03, 'frequency': 0.1}, 'sine': {'amplitude': 0.3, 'frequency': 0.04}, 'triangle': {'amplitude': 0.05, 'frequency': 1.8}, 'bump': {'amplitude': 0.05, 'frequency': 1.8}}

optional arguments:
  -h, --help            show this help message and exit
  --mode {flat,sine,square,triangle,bump}, -m {flat,sine,square,triangle,bump}
                        Road profile mode: (default: sine)
  --amplitude AMPLITUDE, -a AMPLITUDE
                        Amplitude (in meters) for given '--mode'
  --frequency FREQUENCY, -f FREQUENCY
                        Frequency for given '--mode'
  --time-step TIME_STEP, -t TIME_STEP
                        Simulation time step in seconds (default: 0.0005)
  --interval INTERVAL, -i INTERVAL
                        Draw animation frame every <interval> time steps
                        (default: 100)
  --write, -w           Write resulting animation to a video file
