> Currently the whirr infrastructure leverages log4j for system level logging and stdout/stderr for user level. The former is configured via the 'conf/log4j-cli.xml', the latter via the '--quiet' command line paramater.
> It is suggested that the default shipped log4j-cli.xml tune down (or preferable off) its console logging, but remain logging to whirr.log.
> It is also suggested the '--quiet' command paramater be exposed to Handlers as well as Commands, so that they can leverage it.
> In this way, user and system level logging can be delineated (ie console for user logging, whirr.log for system) without each polluting the other.
