    --build=NAME [cvd] -b NAME             Build a CVD file
    --max-bad-sigs=NUMBER                  Maximum number of mismatched signatures
                                           When building a CVD. Default: 3000
    --flevel=FLEVEL                        Specify a custom flevel.
                                           Default: 169
    --cvd-version=NUMBER                   Specify the version number to use for
                                           the build. Default is to use the value+1
                                           from the current CVD in --datadir.
                                           If no datafile is found the default
                                           behaviour is to prompt for a version
                                           number, this switch will prevent the
                                           prompt.  NOTE: If a CVD is found in the
                                           --datadir its version+1 is used and
                                           this value is ignored.
