+
+Description:
+-----------
+
+ $ourname is a "frontend" to the process of ripping audio (cdda) CDs
+ to a hard disk and encoding the audio tracks to either MP3 format or
+ Ogg Vorbis format.
+
+ File names are auto-generated from track titles, with illegal
+ characters removed and spaces converted to underscores.
+
+ Track title, artist, and album names are added to the ID3 tags or
+ Vorbis comments header.
+
+Options:
+-------
+
+ -a ALBUM
+ --album=ALBUM
+ Specify the ALBUM name. Argument ALBUM is _NOT_ optional.
+ Whitespace and punctuation is permitted, but you must protect
+ them from the shell. If this option is omitted, the album
+ name will be prompted for.
+
+ -d DIR
+ --dir=DIR
+ Save encoded files to the directory, DIR. If flac encoding
+ is also requested, see '--flac_copy' option below, the flac
+ files will be saved to DIR/flac. If this option is omitted,
+ it defaults to 'PWD/ARTIST/ALBUM' the album name is first
+ converted to a sane filename.
+
+ -e FILE
+ --edit_rcfile=FILE
+ Edit/create rcfile, FILE, in an editor. If the environment
+ variable EDITOR is not set, vi is used. This implicitly sets
+ rcfile, see '--rcfile' option below.
+
+ -f
+ --flac_copy
+ In addition to encoding the CD audio tracks to MP3 or Ogg
+ Vorbis, create a FLAC audio file for archival purposes.
+
+ -h
+ --help
+ Display this help text and exit.
+
+ -i
+ --interactive
+ Prompt for track titles and artist names.
+
+ -m
+ --mp3
+ Specify MP3 encoding.
+
+ -o
+ --ogg
+ Specify Ogg Vorbis encoding.
+
+ -O
+ --online
+ Attempt to grab the track info from freedb.freedb.org.
+
+ -r FILE
+ --rcfile=FILE
+ Get track titles and artist names from FILE. Argument FILE
+ is _NOT_ optional. The format of FILE is:
+
+ Artist Name|Track Title
+
+ One "record" per line. Whitespace and punctuation is permitted,
+ blank lines are not. And there is no "comment" lines.
+
+ -s ARTIST
+ --sameartist=ARTIST
+ All tracks on the album are by the same ARTIST. Argument
+ ARTIST is _NOT_ optional.
+
+ -t ENCODING_TYPE
+ --type=ENCODING_TYPE
+ This is an alternative to using the -m or -o options.
+ Use ENCODING_TYPE to encode the audio. Valid values for
+ ENCODING_TYPE are "mp3", "ogg".
+
+ -V
+ --version
+ Display version info and exit.
+
+Requirements:
+------------
+
+ zsh http://www.zsh.org/ (mandatory)
+
+ cdparanoia http://www.xiph.org/paranoia/
+ For ripping the audio tracks from CD. (mandatory)
+
+ lame http://www.mp3dev.org/
+ For encoding to MP3 format. (optional if encoding to
+ Ogg Vorbis)
+
+ oggenc http://www.xiph.org/
+ For encoding to Ogg Vorbis format (optional if encoding
+ to MP3)
+
+ flac http://flac.sourceforge.net/
+ For additionally storing audio tracks in FLAC format.
+ (optional)
+
+Files:
+-----
+
+ ${TMPPREFIX}/$ourname.log
+ A log of the incoming TCP traffic from the CDDB server.
+ This will be kept if debugging is turned on, otherwise
+ it is deleted upon successful exit.
+
+ $zdebug
+ Some extra debugging info is logged here.
+
+ rcfile
+ Where $ourname gets track info from. It can be
+ specified on the command line (see -r above) when
+ not using an online CDDB server, otherwise it is
+ created automatically by $ourname.
+
+Environment Variables:
+---------------------
+
+ Some aspects of $ourname can be tweaked by setting the following
+ environment variables.
+
+ DEBUG Set to a non-nil string to turn on debugging.
+
+ zcddb CDDB server to use (default: freedb.freedb.org).
+
+ zuser Name used to log into CDDB server (default: $USER).
+
+ zhost Host used to log into CDDB server (default: $HOST).
+
+ zedit Set to a non-nil string to force $ourname to invoke an
+ editor to create a rcfile.
+
+ zcomment Extra comment field/value to add to ID3 tags/Vorbis
+ comments (default: "Encoded with $ourname").
+
+ Occasionally, the CDDB entries for a given CD are either wrong or
+ have not been formatted correctly. In an attempt to compensate for
+ these types of quirks you can set the following environment variables
+ with $ourname invocation to override the madness...
+
+ ARTIST Override the artist field.
+
+ ALBUM Override the album name.
+
+ YEAR Override year.
+
+ GENRE Override genre.
+
+Example Usage:
+-------------
+
+ Probably the most common usage would be to encode to Ogg/Vorbis
+ format using track info obtained from freedb.freedb.org. Like
+ this...
+
+ \$ $ourname -oO
+
+ Encode to MP3 format, prompting for album name, year, genre, artist,
+ and track titles...
+
+ \$ $ourname -mi
+
+ Encode to Ogg/Vorbis, set album name on the command line, taking
+ track title info from a file, and make a FLAC format backup copy of
+ each track...
+
+ \$ $ourname -a "The Album Name" -o -f -r /path/to/rcfile
+
+ Encode to Ogg/Vorbis, taking track info from a online CDDB server,
+ and override the genre for the album...
+
+ \$ GENRE=alternate $ourname -oO
+
+Exit Status:
+-----------
+
+ $ourname will return the following status codes on exit:
+
+ 0 -- Clean exit (no errors)
+ 2 -- Command line option error
+ 3 -- Missing external command
+ 4 -- CDDB error
+
+Debugging:
+---------
+
+ If you call $ourname with the environment variable DEBUG set to a
+ non nil value, for example: DEBUG=yes $ourname <opts>, $ourname will
+ be called with "set -x".
+
+ "set -x" spams your stdout with a _LOT_ of messages, it would most
+ likely pay you to redirect stdout/stderr to a file.
