=head1 NAME
B<flac2mp3> - transcode FLAC file to MP3 files
=head1 SYNOPSIS
-B<flac2mp3> [B<--lame-options> I<lame-options>] [B<-j> I<jobs>] [B<-q>] [B<-v>] I<file> [...]
+B<flac2mp3> [B<--lame-options> I<lame-options>] [B<-q>] [B<-v>] I<file> [...]
=head1 DESCRIPTION
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
+
=head1 OPTIONS
=over 4
shell, so feel free to take advantage of that. You'll almost
certainly have to put I<lame-options> in single quotes.
-=item B<-j> [B<--jobs>] I<jobs>
-
-Run up to I<jobs> jobs instead of the default 1.
-
=item B<-q> [B<--quiet>]
Suppress status information. This option is passed along to B<flac>
