     3 This directory contains the Standard ML sources of the Isabelle system for
       
     4 the Lambda-Cube.  Important files include
       
     5 
       
     6 ROOT.ML -- loads all source files.  Enter an ML image containing Pure
       
     7 Isabelle and type: use "ROOT.ML";
       
     8 
       
     9 Makefile -- compiles the files under Poly/ML or SML of New Jersey
       
    10 
       
    11 ex.ML -- examples file.  To execute them, enter an ML image
       
    12 containing Cube and type:    use "ex.ML";

    14 NB: the formalization is not completely sound!  It does not enforce
       
    15 distinctness of variable names in contexts!
