  --board-index <index>              Same as '--board', but allows to specify
                                     boards by index instead of by name.
  --remove-other-boards              Remove all boards not specified with
                                     '--board[-index]' from the project before
                                     executing all the other actions. If
                                     '--board[-index]' is not passed, all boards
                                     will be removed. Pass '--save' to save the
                                     modified project to disk.
  --variant <name>                   The name of the assembly variant(s) to
                                     export. Can be given multiple times. If not

  --variant-index <index>            Same as '--variant', but allows to specify
                                     assembly variants by index instead of by
                                     name.
  --set-default-variant <name>       Move the specified assembly variant to the
                                     top before executing all the other actions.
                                     Pass '--save' to save the modified project
                                     to disk.
  --save                             Save project before closing it (useful to
                                     upgrade file format).
  --strict                           Fail if the project files are not strictly
                                     canonical, i.e. there would be changes when
                                     saving the project. Note that this option
                                     is not available for *.lppz files.

Arguments:
  open-project                       Open a project to execute project-related
                                     tasks.
  project                            Path to project file (*.lpp[z]).
