+      The ``short'' version number of the documented software, as
+      specified using the \macro{setshortversion} macro in the

+      the first three characters of the \code{sys.version} value.  For
+      example, versions 2.0b1 and 2.0.1 both have a short version of
+      2.0.  This may not apply for all packages; if
+      \macro{setshortversion} is not used, this produces an empty
