Tagging Options
---------------
Generic tagging options like --tag, --tag-from-file, --long-tag allows you
to set arbitrary tags.
Available tags and their fcc (four char code) for --tag and --tag-from-file
can be found at http://code.google.com/p/mp4v2/wiki/iTunesMetadata
For tags such as Artist where first char of fcc is copyright sign,
you can skip first char and just say like --tag="ART:Foo Bar" or
--tag-from-file=lyr:/path/to/your/lyrics.txt
