+description: """
+Coinductive predicates are greatest fixpoints of monotone functions.
+The `companion' makes it possible to enhance the associated coinduction scheme.
+This library provides a formalisation on enhancements based on the companion, as well as tactics in making it straightforward to perform proofs by enhanced coinduction.
