[vorbis-dev] Reading OGG tags, without libvorbis?

  I've written a simple combined HTTP/MP3/OGG server for streaming audio 
 to clients, which is working well.

  It parses the tag information contained in MP3 files so that it can 
 display files in a more descriptive fashion than 'filename.mp3', and
 now I'd like to do the same for OGG files.

  So that I don't need to impose a dependency I'd like to implement 
 the parsing of the file myself - I don't want to use "vorbis_comment",
 or libvorbis at all.

  I've grabbed a copy of vorbis-tools to look at how 'vorbiscomment'
 works - but I'm confused as to the OGG header + comment formats.

  Is there a simple description of the format of the header, and the
 fields?

  The closest that I've seen is the following document, but it doesn't
 contain enough of a description to allow me to write code:

   http://www.xiph.org/ogg/vorbis/doc/v-comment.html

  Any pointers would be much appreciated.

Steve
