Options:
--path <dir> Where your music collection is found
--db <file> Prefix for output files. Defaults to tagcache.
--strip <path> Removes this string from the left of all file names
--add <path> Adds this string to the left of all file names
--dirisalbum Use dir name as album name if the album name is missing in the
tags
--littleendian Write out data as little endian (for simulator)
--verbose Shows more details while working
--help This text
