This is usually done by renaming one of the +candidate-tags files and deleting the others. Don't forget to fill in +the DATE tag in the selected candidate before renaming it. If +B<fa-rip> could not find any tag information from MusicBrainz, you'll +have to fill out the candidate-tags-0 template. + +=head1 OPTIONS + +=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> "$@"'.
