       %%%  Preliminaries

	   1) working scala compiler ($fjbg.jar, $scala.jar and $tools.jar)

	   if you want to use the latest CVS one, type 

       make jar target=LIBRARY
       make jar target=TOOLS

	   and set the variables to the places in your projectoutputdir

	   2) working pizza compiler ($jaco.jar)

    (*3) for Java, and pico, files are only recompiled if the source file is
    newer than the class file. This would work for scala, but mixin
    composition sometimes needs additional source files. These can
    be unavailable for some reason.
