[Flac] metaflac

[Dat Head]

i put this in a script and called it metaflac-showall since that was
more intuitive to me,
but here is how to dump all tags and then you can check the output for the
specific one you want:

    metaflac --export-tags-to=-

but i guess that returns more info than you want (the tag names and their
values)
