Cube: Barendregt's Lambda-Cube
This directory contains the Standard ML sources of the Isabelle system for
the Lambda-Cube. Important files include
ROOT.ML -- loads all source files. Enter an ML image containing Pure
Isabelle and type: use "ROOT.ML";
Makefile -- compiles the files under Poly/ML or SML of New Jersey
ex.ML -- examples file. To execute them, enter an ML image
containing Cube and type: use "ex.ML";
NB: the formalization is not completely sound! It does not enforce
distinctness of variable names in contexts!
