ToDo:
  19.12.01: Add all (or some of) the new id3tags since v3 of id3tag.library

1.2 [09.02.02]
  New: New arg: REQ/S, if specified the infos are display in a requester (OK)
       I use a MUI requester here, but if MUI isn't installed a standard req
       should be used.
  New: New arg: ALF/S, to append a linefeed at the end, so you don't have put
       a "\n" in your lformat.

1.1 [19.12.01]
  New: New arguments: T=Title/K, Ar=Artist/K, Al=Album/K, Y=Year/K,
       C=Comment/K, G=Genre/K, Track/K.
       These args are used to WRITE these tags to the file!
       Then no output will be written!
  Chg: the LF=LFORMAT argument is now a '/K' argument, which means you have
       to specify the argument-keyword (LFORMAT or LF) if you use it.
  Chg: Changed the format of the 'ALL' option
  New: added '%V' for the ID3 Version
  New: The date of the mp3-file will be set to the date before writing
       the id3tags!
  Chg: Removed the filename-option from the default format.
  Chg: Changed the help-page a little bit

1.0 [20.03.01]
  first version, only reading of id3tags are supported
