-B<flac2mp3> transcodes the FLAC file I<file> to MP3 files. I<file> is
-the kind of FLAC file B<fa-flacd> generates. That is, it contains a
-cue sheet, one TITLE tag per track listed therein, and ARTIST, ALBUM,
-and DATE tags.
+B<flac2mp3> transcodes the FLAC files I<file> to MP3 files. I<file>
+may be the kind of FLAC file B<fa-flacd> generates. That is, it
+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
