+<H2>ex--Miscellaneous Examples</H2>
+
+<P>This directory presents a number of small examples, illustrating various
+features of Isabelle/HOL.
+
+<UL>
+<LI>Files <KBD>cla.ML</KBD> demonstrates the
+power of Isabelle's classical reasoner.
+
+<LI>Files <KBD>meson.ML</KBD> and <KBD>mesontest.ML</KBD> present an
+implementation of the Model Elimination (ME) proof procedure, which is even
+more powerful than the classical reasoner but not generic.
+
+<LI><KBD>InSort</KBD> and <KBD>Qsort</KBD> are correctness proofs for sorting
+functions.
+
+<LI><KBD>Primes</KBD> is a theory of the <EM>divides</EM> relation, the
+greatest common divisor and Euclid's algorithm.
+
+<LI><KBD>NatSum</KBD> demonstrates the power of permutative rewriting.
+Well-known identities about summations are proved using just induction and
+rewriting.
+
+<LI><KBD>MT</KBD> is a preliminary version of Jacob Frost's coinduction
+example. The full version is on the directory <KBD>ZF/Coind</KBD>.
