Split2flac splits one big APE/FLAC/WV/WAV audio image (or a collection of
such files, recursively) with CUE sheet into FLAC/M4A/MP3/OGG_VORBIS/WAV
tracks with tagging, renaming, charset conversion of cue sheet, album cover
images. It also uses configuration file, so no need to pass a lot of
arguments every time, only an input file. Should work in any
POSIX-compliant shell.
