=head1 DESCRIPTION
-B<fa-flacd>, B<fa-rip>, and B<fa-tags> together comprise
-B<flac-archive>, a system for archiving audio CDs to single FLAC
-files. B<fa-flacd> is the guts of the system. It runs in the
-directory where the audio archives are stored, scanning for new CDs to
-encode and rename; it never exits. B<fa-rip> generates the inputs for
-B<fa-flacd>: the ripped WAV file, Vorbis tags, and a cuesheet.
-B<fa-tags> is not meant to be run directly; B<fa-rip> uses it to
-generate the candidate Vorbis tags.
-
-All three programs expect to be run from the same directory. They use
-that directory to manage directories named by artist and by disc ID.
-Intermediate files are written to the disc ID directory. B<fa-flacd>
-processes the disc ID directories into per-album files in the artist
-directories.
-
-=head2 FA-FLACD
-
-B<fa-flacd> does not exit; it runs until the user kills it. Every 5
-seconds it scans its current directory for directories with a file
-called "tags" and creates a processing job for each one. The number
-of jobs B<fa-flacd> attempts to run is controlled by the B<-j> option
-and defaults to 4. B<fa-flacd> will print diagnostic output when the
-B<-v> option is given.
+B<fa-flacd> and B<fa-rip> together comprise B<flac-archive>, a system
+for archiving audio CDs to single FLAC files. B<fa-flacd> is the guts
+of the system. It runs in the directory where the audio archives are
+stored, scanning for new ripped CDs to encode and rename; it never
+exits. B<fa-rip> generates the inputs for B<fa-flacd>: the ripped WAV
+file, Vorbis tags, and a cuesheet.
+
+Both programs expect to be run from the same directory. They use that
+directory to manage directories named by artist. Intermediate files
+are written to temporary directories here. B<fa-flacd> processes the
+temporary directories into per-album files in the artist directories.
+
+Every 5 seconds, B<fa-flacd> scans its current directory for
+directories with a file called "tags" and creates a processing job for
+each one. The number of jobs B<fa-flacd> attempts to run is
+controlled by the B<-j> option and defaults to 4. B<fa-flacd> will
+print diagnostic output when the B<-v> option is given.
A processing job first renames the directory's "tags" file to
"using-tags" so that B<ra-flacd> will not try to start another job for
condition and renames "using-tags" back to "tags". Next, it encodes
the "wav" file to a FLAC file, using the "cue" file for the cuesheet
and "using-tags" for Vorbis tags. Any diagnostic output is saved in
-the "log" file. Finally, the "cue" and "log" files are moved to the
-artist directory (and named by album) and the ID directory is removed.
-
-=head2 FA-RIP
-
-B<fa-rip> uses C<cd-discid(1)> to retrieve the disc ID and track
-information. It creates a directory named by ID for storage of its
-intermediate files. It passes the C<cd-discid(1)> output as
-command-line arguments to B<fa-tags> in the background. It then uses
-C<cdrdao(1)> to create the "cue" file in the background. Finally, it
-execs C<cdparanoia(1)> to rip the CD to the "wav" file.
-
-In order for this CD to be processed by B<fa-flacd>, the user must
-create a "tags" file. This is usually done by renaming one of the
-candidate-tags files and deleting the others.
-
-=head2 FA-TAGS
-
-B<fa-tags> uses C<cddb-tool(1)> (from the B<abcde> package) to
-populate candidate-tags files. These are numbered in the order of
-entries read from CDDB, e.g. candidate-tags-1, candidate-tags-2, etc.
-B<fa-tags> also creates candidate-tags-0, which has the correct fields
-for this CD (including correct number of TITLE= lines), but with all
-fields blank.
-
-B<fa-tags> expects the output of C<cd-discid(1)> as command-line
-arguments. That is, the disc ID, number of tracks, list of track
-offsets, and total length of the CD in seconds.
-
-=head1 ENVIRONMENT
+the "log" file. Finally, B<fa-flacd> moves the "cue" and "log" files
+to the artist directory (named by album) and removes the temporary
+directory.
+
+If the temporary directory contains an executable file named
+"post-processor", B<fa-flacd> executes that file with the relative
+path to the output FLAC file as an argument. The output files are in
+their final location when "post-processor" starts. Possible uses are
+running B<flac2mp3>, moving the output files to a different location,
+removing the lock file, or adding to a database. The standard input,
+output, and error streams are inherited from B<fa-flacd>, so they may
+be connected to anything from a tty to /dev/null. This means that you
+may want to redirect these streams, if you want to save them or do any
+logging.

+=head1 OPTIONS
=over 4
-=item CDDBURL
+=item B<-j> [B<--jobs>] I<jobs>
-B<fa-tags> uses this to retrieve candidate Vorbis tags. Defaults to
-"http://freedb.freedb.org/~cddb/cddb.cgi".
+Run up to I<jobs> jobs instead of the default 4.
-=item CDDEV
+=item B<-v> [B<--verbose>]
-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.
+Print diagnostic information.
