+# perl-Tie-RefHash
+
+This module provides the ability to use references as hash keys if you first
+"tie" the hash variable to this module. Normally, only the keys of the tied
+hash itself are preserved as references; to use references as keys in
+hashes-of-hashes, use Tie::RefHash::Nestable, included as part of
+Tie::RefHash.
