If there's no complete author tag, we need to add an opening
quote character manually. See the EBU entry.

The normative reference is now the channel configurations
give directly in the draft.

Previous markup was invalid.

I've done some editing for clarity, but more needs to be done.
The language needs clean-up, we should forward-reference the LPC
Extrapolation section, and we need a reference for actually
computing linear prediction coefficients.

More recent versions of draft-sheffer-running-code suggest referring
to a wiki. We'd like to try maintaining the implementation status
separately.

The channel mapping family nested lists were hard to read.
Promoting each family description to a subsection makes it
more clear where one is in the document.

Also add suggested downmix matricies. These are what we're
currently using in opus-tools, opusfile, and Firefox.
Ascii-art matrices in 69 columns is hard.

With xml2rfc 2.3.9, I was getting the 'audio/ogg; codecs=opus'
figure hoisted out of the the containing paragraph, which was
very confusing.

I've tried to improve this by moving the surrounding paragraph
into the figure using the <preamble> and <postamble> tags, as
in the example in draft-mrose-writting-rfcs.

Unfortunately this still isn't perfect. Since the surrounding
paragraph is part of the figure we can't set align="center" on
the figure itself, and the processor seems to ignore it on the
artwork element. I've compensated by adding some leading
whitespace.

Mostly just being more verbose.

This clarifies the meaning in surround configurations and better
distinguishes it from 'rear center'.

Add sections on VLC, foobar200, and Rockbox.
Be more complete about listing which features of the format are
 actually supported by each implementation.
Still need to do more testing for Chrome, FFmpeg, and libav.

We mean to make .opus only for degenerate--not concurrently
multiplexed or grouped--but optionally sequentially multiplexed
or chained physical Ogg streams.

However, we don't mean to say you can't use this draft with
such streams.

Also, replace the reference to RFC3534 with RFC5334, which
obsoletes the previous reference by defining video/ogg and
audio/ogg.

This is based on the experiment described in
http://tools.ietf.org/html/draft-sheffer-running-code-01

I've listed several major implementations. Their formatting
could probably be better. More obviously, this really demonstrates
the need for a good test suite to evaluate converage and compliance
with all these different implementations.

This is true, but not important to understanding the limitation.

The command line has changed, for the better, but we need to
update the way we call it. Also adds an install hint if it's
not found on the path.

NB I tried to detect and fallback to the old syntax for the
version 1 (TCL) implementation but this is hard because it
doesn't support any switches (like --version) and it no
longer parses our remote entities.

Made RFC6716 a normative reference, removed non-sensical constraints,
updated contact info, ...

Thanks to Randell Jesup for the feedback.

This allows the sender parameters sprop-maxcapturerate and
 sprop-stereo to be specified on a per-SSRC basis, instead of just
 per m-line.

Makefile.draft got renamed to Makefile.unix in e91dfa0f, but
 build_draft.sh was not updated.
