+    (description "This package offers a means to remove the limitation, of
+only two properties, that is inherent in the way LaTeX's reference system
+works.  The package implements an extensible referencing system, where
+properties may be defined and used in the course of a document.  It provides
+an interface for macro programmers to access the new reference scheme and some
+modules that use it.  Modules available are:
+@table @code
+@item zref-user
+use zref for traditional labels and references;
+@item zref-abspage
+retrieve absolute page numbers (physical pages, as opposed to the logical page
+number that is normally typeset when a page number is requested;
+@item zref-lastpage
+provide a zref-label for the last page of the document;
+@item zref-nextpage
+provide the page number of the next page of the document;
+@item zref-totpages
+provide the total number of pages in the document;
+@item zref-pagelayout
+provide the page layout parameters of a each page (which may then be printed
+at the end of the document);
+@item zref-perpage
+make a counter reset for each new page;
+@item zref-titleref
+make section title or caption text available through the reference system;
+@item zref-savepos
+make positions on a page available;
+@item zref-dotfill
+controlled dot-filling
+@item zref-env
+record the latest environment's name and the line it started on;
+@item zref-xr
+provide the facilities of the xr and xr-hyper packages.
