.BR abcde
is designed to automate this. It will take an entire CD and convert it into
a compressed audio format - Ogg/Vorbis, MPEG Audio Layer III, Free Lossless
-Audio Codec (FLAC), Ogg/Speex, MPP/MP+(Musepack) and/or M4A (AAC) format(s).
+Audio Codec (FLAC), Ogg/Speex, MPP/MP+(Musepack), M4A (AAC) or Opus format(s).
With one command, it will:

.B \-o [filetype][:filetypeoptions]
Select output type. Can be "vorbis" (or "ogg"), "mp3", "flac", "spx", "mpc",
-"m4a" or "wav". Specify a comma-delimited list of output types to obtain all
-specified types. See the OUTPUTTYPE configuration variable. One can pass
+"m4a", "wav" or "opus". Specify a comma-delimited list of output types to obtain
+all specified types. See the OUTPUTTYPE configuration variable. One can pass
options to the encoder for a specific filetype on the command line separating
them with a colon. The options must be escaped with double-quotes.
.TP
will process the entire CD. Accepts ranges of track numbers -
"abcde 1-5 7 9" will process tracks 1, 2, 3, 4, 5, 7, and 9.
.SH OUTPUT
-Each track is, by default, placed in a separate file named after the track
-in a subdirectory named after the artist under the current directory.
-This can be modified using the OUTPUTFORMAT and VAOUTPUTFORMAT
-variables in your \fIabcde.conf\fR. Each file is given an extension identifying
-its compression format, 'vorbis' for '.ogg', '.mp3', '.flac', '.spx', '.mpc', '.aac' or '.wav'.

.SH CONFIGURATION
\fBabcde\fR sources two configuration files on startup - \fI/etc/abcde.conf\fR and
\fI$HOME/.abcde.conf\fR, in that order.
Specifies the style of encoder to use for M4A (AAC) encoder. We support \'faac\'
as \'default\' but support is there for neroAacEnc as well.
.TP
+.B OPUSENCODERSYNTAX
+Specifies the style of encoder to use for the Opus encoder. At this point only
+\'opusenc\' is available for Opus encoding.
+.TP
.B NORMALIZERSYNTAX
Specifies the style of normalizer to use. Valid options are \'default\'
and \'normalize'\ (and both run \'normalize-audio\'), since we only support it,
.B PATHNAMES
The following configuration file options specify the pathnames of their
respective utilities: LAME, TOOLAME, GOGO, BLADEENC, L3ENC, XINGMP3ENC, MP3ENC,
-VORBIZE, OGGENC, FLAC, SPEEXENC, MPCENC, AACENC, ID3, EYED3, METAFLAC,
+VORBIZE, OGGENC, FLAC, SPEEXENC, MPCENC, AACENC, OPUSENC, ID3, EYED3, METAFLAC,
CDPARANOIA, CDDA2WAV, CDDAFS, CDDISCID, CDDBTOOL, EJECT, MD5SUM, DISTMP3,
VORBISCOMMENT, NORMALIZE, CDSPEED, MP3GAIN, VORBISGAIN, MPPGAIN, MKCUE, MKTOC,
CUE2DISCID (see option "\-X"), DIFF and HTTPGET.
If you wish to specify command-line options to any of the programs \fBabcde\fR uses,
set the following configuration file options: LAMEOPTS, TOOLAMEOPTS, GOGOOPTS,
BLADEENCOPTS, L3ENCOPTS, XINGMP3ENCOPTS, MP3ENCOPTS, VORBIZEOPTS, OGGENCOPTS,
-FLACOPTS, SPEEXENCOPTS, MPCENCOPTS, AACENCOPTS, ID3OPTS, EYED3OPTS, MP3GAINOPTS,
-CDPARANOIAOPTS, CDDA2WAVOPTS, CDDAFSOPTS, CDDBTOOLOPTS, EJECTOPTS, DISTMP3OPTS,
-NORMALIZEOPTS, CDSPEEDOPTS, MKCUEOPTS, VORBISCOMMMENTOPTS, METAFLACOPTS,
+FLACOPTS, SPEEXENCOPTS, MPCENCOPTS, AACENCOPTS, OPUSENCOPTS, ID3OPTS, EYED3OPTS,

+DISTMP3OPTS, NORMALIZEOPTS, CDSPEEDOPTS, MKCUEOPTS, VORBISCOMMMENTOPTS, METAFLACOPTS,
DIFFOPTS, FLACGAINOPTS, VORBISGAINOPTS and HTTPGETOPTS.
.TP
.B CDSPEEDVALUE
Specifies the encoding format to output, as well as the default extension and
encoder. Defaults to "vorbis". Valid settings are "vorbis" (or "ogg")
(Ogg/Vorbis), "mp3" (MPEG-1 Audio Layer III), "flac" (Free Lossless Audio
-Codec), "spx" (Ogg/Speex), "mpc" (MPP/MP+ (Musepack)), "m4a" (for M4A (AAC)) or
-"wav" (Microsoft Waveform). Values like "vorbis,mp3" encode the tracks in both
-Ogg/Vorbis and MP3 formats. For example
+Codec), "spx" (Ogg/Speex), "mpc" (MPP/MP+ (Musepack)), "m4a" (for M4A (AAC)),
+"wav" (Microsoft Waveform) or "opus" (Opus Interactive Audio Codec). Values
+like "vorbis,mp3" encode the tracks in both Ogg/Vorbis and MP3 formats. For example
