- HOL: Higher-Order Logic
-
-This directory contains the Standard ML sources of the Isabelle system for
-Higher-Order Logic. 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 -- subdirectory containing examples. To execute them, enter an ML image
-containing HOL and type: use "ex/ROOT.ML";
-
-Subst -- subdirectory defining a theory of substitution and unification.
-
