Hi,

Thanks for bringing this up again. The Scala scripting engine for Sling 
evolved somewhat since it was copied over to clerezza: Sling 
dependencies have been removed and factored out. AFIK the current 
version used in clerezza does not fulfill some of the requirements of 
the Sling scripting engine (configurability, abstraction of file 
system). However, since I wont be able to contribute much in the coming 
weeks, I think the version of clerezza might well serve as a starting 
point. I'd be happy to merge the changes required by Sling into it later 
on.

However, I think the Scala incubator [1] might be a better place for the 
Scala scripting engine. That way there is the chance for it making it 
into the Scala distro some time in the future.

Michael
