Usage:
   shocked-client --path=<datadir>... [--autosave=<sec>] [--scale=<scale>] [--invertedSliderScroll]
   shocked-client -h | --help
   shocked-client --version

Options:
   -h --help               Show this screen.
   --version               Show version.
   --path=<datadir>        A path to data directory for inplace modifications. Repeat option for multiple directories.
   --autosave=<sec>        A duration, in seconds (1..1800), after which changed files are automatically saved. Default: 5.
   --scale=<scale>         A factor for scaling the UI (0.5 .. 1.0). 1080p displays should use default. 4K most likely 2.0. Default: 1.0.
   --invertedSliderScroll  Specify to have sliders go "down" if scrolling "up" (= old behaviour)
