I would like to activate the logback internal devbug mode (to get more information during the logback setup).
I know how to do this in xml file (using a debug="true" in the configuration declaration). I discovered that it could be possible to force the flag using a system property (but I didn't achieved that)
OK I've seen this comment in the GafferConfigurator.groovy :
// For now, Groovy/Gaffer configuration DSL does not support "debug" attribute. But in order to keep
// the conditional logic identical to that in XML/Joran, we have this empty block.
So we can conclude it's not yet implemented...
