# Vorbiscomment from Filename
# usage: vcfromfilename [options] <files>
# options:
# -n: Only set the track number
# -0: Leading 0s in track number are preserved
# -T: Tag names (not tag content) written to the metadata in all caps
#
# Adds Vorbiscomment data to ogg vorbis and flac files based on the filename.
# Files should be in Anna's arbitrary file name standard, which is:
# artist/album/artist-tracknum-title.(ogg|flac|mp3)
#
# The top-level directory (artist) is optional. Filenames should contain no
# spaces; underscores in the filename are converted to spaces in the resulting
# metadata
#
# Requires vorbiscomment and metaflac
