+# SRFI 128 - Comparators
+
+The `(srfi 128)` provides comparators, which bundle a type test predicate, an equality predicate, an ordering predicate, and a hash function into a single Scheme object. By packaging these procedures together, they can be treated as a single item for use in the implementation of data structures.
+
+See the [SRFI document](http://srfi.schemers.org/srfi-128/srfi-128.html) for more information.
