+universally unique identifiers (UUIDs) according to \rfc{4122}. The
+RFC defines several different UUID versions that are generated from a

+\function{uuid3()}, \function{uuid4()}, and
+\function{uuid5()} to generate different versions of UUID. (Version 2 UUIDs
+are not specified in \rfc{4122} and are not supported by this module.)
