B<flac2mp3> - transcode FLAC file to MP3 files
contains a cue sheet, one TITLE tag per track listed therein, and
ARTIST, ALBUM, and DATE tags.
+Note that lame is retarded, and parses B<LANG> directly itself! So, in order
+for it to transcode textual tags, you must specify the encoding in LANG, e.g.
+LANG=en_US.utf-8
