This directory contains the Standard ML sources of the Isabelle system for
First-Order Logic (constructive and classical versions).  For a classical
sequent calculus, see LK.  Important files include

<DD>loads all source files.  Enter an ML image containing Pure
Isabelle and type: use "ROOT.ML";<P>
