Name:                hashable

Version:             1.2.6.1

Synopsis:            A class for types that can be converted to a hash value

Description:         This package defines a class, 'Hashable', for types that

                     can be converted to a hash value.  This class

                     exists for the benefit of hashing-based data

                     structures.  The package provides instances for

                     basic types and a way to combine hash values.
