+ (description "UCONS is a Common Lisp library providing unique conses.
+Unique conses are different from regular conses in that, in addition to their
+@code{car} and @code{cdr}, they maintain a table of past users. Also, the
+@code{cdr} of each ucons is restricted to other uconses or @code{nil}.
+Uconses are meant for those situations where even reusing regular conses (to
+avoid consing) is too computationally expensive.")
