+=head1 DESCRIPTION
+
+B<fa-rip> creates a temporary directory for storage of its
+intermediate files, runs C<mkcue(1)> to create the "cue" file, uses
+MusicBrainz to generate candidate tags files, and runs
+C<cdparanoia(1)> to rip the CD to the "wav" file.
+
+In order for this CD to be processed by B<fa-flacd>, you must create a
+"tags" file.  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<-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<-t> [B<--tracks>] I<track-count>
+
+Archive only the first I<track-count> tracks.  This is handy for
+ignoring data tracks.

+
+=head1 ENVIRONMENT
+
+=over 4
+
+=item CDDEV
+
+B<fa-rip> uses this to rip audio and save the cuesheet for a CD.  It
+makes some effort to check some common device names for FreeBSD,
+Linux, and NetBSD by default.
