+
+[classref boost::hash] is an implementation of the __hash-function__ object
+specified by the __tr1-full__ (TR1). It is the default hash function for
+__unordered__, __intrusive__'s unordered associative containers, and
+__multi-index-short__'s hash indicies and __bimap__'s `unordered_set_of`.
+
+As it is compliant with __tr1__, it will work with:
+
+* integers
+* floats
+* pointers
+* strings
+
+It also implements the extension proposed by Peter Dimov in issue 6.18 of the
+__issues__ (page 63), this adds support for:
+
+* arrays
+* `std::pair`
+* the standard containers.
+* extending [classref boost::hash] for custom types.
+
+[note
+This hash function is designed to be used in containers based on
+the STL and is not suitable as a general purpose hash function.
+For more details see the [link hash.rationale rationale].
