=head1 DESCRIPTION
=over 4
+=item B<--artist> I<artist> B<--title> I<title>
+
+Write candidate-tags files based on I<artist> and album I<title>.
+Useful if you've already ripped wav files with some other program and
+just need to set things up for B<fa-flacd>.
+
=item B<-d> [B<--device>] I<device>
Use I<device> as the CD-ROM device, instead of the default
"/dev/cdrom" or the environment variable CDDEV.
+=item B<-m> [B<--no-musicbrainz>]
+
+Don't connect to MusicBrainz, just write candidate-tags-0.
+
=item B<-p> [B<--post-processor>] I<post-processor>
Create a "post-processor" file in the temporary directory containing
the line 'I<post-processor> "$@"'. See B<fa-flacd>'s man page for
information about this hook.
+=item B<-s> [B<--single-file>]
+
+Rip whole disc to one wav file and configure B<fa-flacd> to encode it
+to one FLAC file with embedded cuesheet.
+
=item B<-t> [B<--tracks>] I<track-count>
Archive only the first I<track-count> tracks. This is handy for
