There are no plans in this area but we are certainly open for 
suggestions. Generating IDE project files is definitely something we 
want to support. We just haven't gotten to it yet.

The removal of ALL_SRC_DIRS was for code simplification in the makefiles 
and because javac has changed the way it wants the source roots 
specified in jake. I did not realize there was an external dependency on 
this construct.
