    .. code:: yoscrypt

        read_liberty [filename]

    ::

        Read cells from liberty file as modules into current design.


    .. code:: yoscrypt

        -lib

    ::

            only create empty blackbox modules


    .. code:: yoscrypt

        -wb

    ::

            mark imported cells as whiteboxes


    .. code:: yoscrypt

        -nooverwrite

    ::

            ignore re-definitions of modules. (the default behavior is to
            create an error message if the existing module is not a blackbox
            module, and overwrite the existing module if it is  a blackbox module.)


    .. code:: yoscrypt

        -overwrite

    ::

            overwrite existing modules with the same name


    .. code:: yoscrypt

        -ignore_miss_func

    ::

            ignore cells with missing function specification of outputs


    .. code:: yoscrypt

        -ignore_miss_dir

    ::

            ignore cells with a missing or invalid direction
            specification on a pin


    .. code:: yoscrypt

        -ignore_miss_data_latch

    ::

            ignore latches with missing data and/or enable pins


    .. code:: yoscrypt

        -setattr <attribute_name>

    ::

            set the specified attribute (to the value 1) on all loaded modules
