[rtcweb] Document mechanics for JSEP

[Ted Hardie <[e-mail]>]

Howdy,

In order to increase the velocity of our work, the chairs would like to
make some changes to how we approach the document editing for JSEP.  First,
we have asked Eric Rescorla to act as an editor of the document.  Cullen
and Justin will, of course, continue to be listed as authors, but the
day-to-day editorial work will be done by ekr.  Second, we would like to
work using github as the repository of the working copy, with pull requests
for specific text changes there.  The repository is at:

https://github.com/rtcweb-wg/jsep

Note that issues can be raised there, but that non-editorial issues must
then be submitted to the mailing list, and  substantive discussion of those
issues should remain on the mailing list.

This approach has worked well in the HTTP and TLS working groups, and we
hope it can help us deliver in a timely way.

Let us know if there are questions or concerns,

thanks,

Ted and Sean (Cullen recused)
