[HECnet] PyDECnet setup

[Paul Koning]

Well, it's in doc/config.txt.  And actually it says something I had forgotten.  If you don't specify a cert it defaults to decnet.pem.  So it has a cert name either way.

I assume that file decnet.pem doesn't actually exist.  So you should get an error message, and "cert decnet.pem doesn't exist" would be a lot clearer.

Meanwhile, the configuration file details are described pretty carefully in doc/config.txt; reviewing that can be useful.

On the subject of the qmax spec, yes, for the moment that's a good idea.  I need to implement congestion control one of these days, the algorithms are documented but I haven't gotten around to that yet.
