The nux logging defaults to warning. The UNITY_LOG_SEVERITY environment
variable is something that is handled in the initialisation of unity
itself to configure the logging.

By default, I think the logging goes to stderr. Any capturing of the
logging is handled by something wrapping the executable.

The logging code itself does handle multiple log writers IIRC.

/me goes to glance at the code...

http://bazaar.launchpad.net/~unity-team/nux/trunk/view/head:/NuxCore/Logger.h#L100

The comment there mentions this to configure logging:

nux::logging::configure_logging(::getenv("MY_APP_LOGGING_CONFIG"));

Please read the header file to work out how to use it.

The comments there do, I think, give reasonable examples on how to use it.

Good luck.
