                           creates v1.1 tag, providing a total forces v2.0).

    --genre-list    print alphabetically sorted ID3 genre list and exit
    --ignore-tag-errors  ignore errors in values passed for tags

    Note: A version 2 tag will NOT be added unless one of the input fields
    won't fit in a version 1 tag (e.g. the title string is longer than 30
    characters), or the '--add-id3v2' or '--id3v2-only' options are used,
    or output is redirected to stdout.


MS-Windows-specific options:
    --priority <type>  sets the process priority:
                         0,1 = Low priority (IDLE_PRIORITY_CLASS)
                         2 = normal priority (NORMAL_PRIORITY_CLASS, default)
                         3,4 = High priority (HIGH_PRIORITY_CLASS))
    Note: Calling '--priority' without a parameter will select priority 0.

Misc:
    --license       print License information



  Platform specific:
    --noasm <instructions> disable assembly optimizations for mmx/3dnow/sse
