unknown option: -headless
Usage: [<option>...] [<imageName> [<argument>...]]
       [<option>...] -- [<argument>...]

Common <option>s:
  --help                 print this help message, then exit
  --memory <size>[mk]    use fixed heap size (added to image size)
  --headless             run in headless (no window) mode (default: false)
  --nohandlers           disable sigsegv & sigusr1 handlers

  <imageName> defaults to `Pharo.image'.
  If `--memory' is not specified then the heap will grow dynamically.
  <argument>s are ignored, but are processed by the Squeak image.
  The first <argument> normally names a Squeak `script' to execute.
  Precede <arguments> by `--' to use default image.
