UPnP BasicManagement / DLNA +DIAGE+
===================================

Rygel includes an optional BasicManagement:2[1] service implementation.
The implementation allows running diagnostic tools (Ping, NSLookup and
Traceroute) and querying their results remotely. Typically this service
would be running on a mediarenderer or mediaserver device that wants to
be compliant with the DLNA Diagnostics Guidelines[2].

The BasicManagement service is not started by default. To enable it for
a plugin add "diagnostics=true" in the configuration section for that
plugin in rygel.conf:
  [Playbin]
  diagnostics=true

The service implementation is portable in the sense of compiling on any
Posix platform but it does use system tools (ping, nslookup, traceroute)
and parses their output. It has only been tested with standard linux
implementations but is likely to not produce good results on other OSes,
even busybox may require additional work.
