+<h3>HOLCF: A higher-order version of LCF based on Isabelle/HOL</h3>
+
+HOLCF is the definitional extension of Church's Higher-Order Logic with
+Scott's Logic for Computable Functions that has been implemented in the
+theorem prover Isabelle. This results in a flexible setup for reasoning
+about functional programs. HOLCF supports standard domain theory (in particular
+fixpoint reasoning and recursive domain equations) but also coinductive
+arguments about lazy datatypes.
