[logback-user] What support is needed to run with logback.groovy configuration?

Thanks, Robert, now we are getting somewhere.

Indeed, my logback.groovy contains the line
	def logdir = ${files.root}/logdir

This came from a translation of my logback.xml by ceki's handy converter 
webpage.  Logback.xml had
	<property name="logdir" value = "${files.root}/logdir" />

where files.root is the name of a System property.

So the question is, is there a way to express a system property name in 
groovy and what is it?

Consequently you don't get compile time indicators as to whether you are getting the syntax of the DSL right; instead it fails at runtime, complaining that a property was not present.
