    If -o (output-file) argument is given, the font
    list is then saved to the output file, either as
    a single font, if there is only one font, or as
    a collection otherwise.

    If -y (font-number) argument is given, only the
    specified font from collections is opened.

    The above allow extracting a single font from a
    collection, or combining multiple fonts into a
    collection.

    to the TTFont() or TTCollection() constructors.
