=head1 NAME

dr_cdrip - rip audio cd's to ogg

=head1 SYNOPSIS

B<dr_cdrip> B<[>I<args>B<]> < I<id3-tag-file>

=head1 DESCIPTION

dr_cdrip sets up a cdparanoia(1) - oggenc(1) pipe for each track on your 
audio cd, so that the audio on your cd will be stored as .ogg files on your 
harddisk. I<args> will get passed to each songs' oggenc(1) invocation.

I<id3-tag-file> could look like this:

 Jaffa - Star 67
 Think of one - Den Antwaarpse Shabi
 Klute - Angry Woman
 Electrotwist - The Smurfer

Evil characters are discarded from the file, we don't want
them to appear in filenames. If a line lacks a ' - ', the
line is assumed to be a title. 

Defauls setting of oggenc(1)'s --quality level is 7, override by
setting the CDRIP_QUALITY environment variable.

Note: mp3's id3 tags seem to be called "comments" in the .ogg world.

=head1 EXAMPLE

 dj@gelfand ~$ export CDRIP_QUALITY=9
 dj@gelfand /h.../The_New_York_Contemporary_Five$ dr_cdrip \
  -l "The New York Contemporary Five" -a "Archie Shepp" \
  -c "description=Don Cherry: crnt, Archie Shepp: ts, Don \
  Moore: b, JC Moses:d" -c "genre=Jazz" -c "date=1963" \
  -c "location=Copenhagen" \
  -c "copyright=1991 Storyville Records" -c "license=All Rights Reserved" \
  -c "organization=Storyville" \
  -c "contact=http://www.storyville-records.com/" \
  -c "diskid=bd10c70d" < /tmp/songlist 

See DISCID HOWTO on
http://freedb.org/modules.php?name=Sections&sop=viewarticle&artid=6 for info on
disk id.  Beware!  A diskid comment is _not_ mentioned in the xiph.org
suggestions!

(oggenc's -t will be used by dr_cdrip. -a might be.)

supported extra comments are (see ogg123.c) 

 VERSION=, TRACKNUMBER=, ISRC=

ARTIST is -a, ALBUM is -l TITLE is -t.

VERSION is e.g. 'Biosphere Foo Mix'.  Multipe ARTIST tags can occur; this use
is encouraged if applicable.  -c foo will be displayed by ogg123 as 'Comment:
foo'.

Run something like:

 cdcd tracks | sed 's/^.*\]\ *//' | sed 's/\ $//'

to extract a songlist from a cddb database.

=head1 BUGS

The format of the songinfo input file is non-standard.  Support for cddb is
lacking.
