+Root file for pure Isabelle: all modules in proper order for loading
+Loads pure Isabelle into an empty database.

+To build system, use Makefile (Poly/ML) or Makefile.NJ (New Jersey ML)
+
+TO DO: 
+instantiation of theorems can lead to inconsistent sorting of type vars if
+'a::S is already present and 'a::T is introduced.
