Usage: bv_maker [global options] testref

    Executes tests in the testref mode (used to generate reference files).

Options:
  -h, --help            show this help message and exit
  --only-if-default     only perform this step if it is a default step, or
                        specified in the "default_steps" option of
                        bv_maker.cfg config file. Default steps are normally
                        "sources" for source sections, and "configure build"
                        for build sections
  -m MAKE_OPTIONS, --make_options=MAKE_OPTIONS
                        options passed to make (ex: "-j8") during test
                        reference generation. Same as the configuration option
                        make_options but specified at runtime. The commandline
                        option here overrides the bv_maker.cfg options.
