+    (description
+     "The Structstrings package implements the widely used dot bracket
+annotation for storing base pairing information in structured
+RNA. Structstrings uses the infrastructure provided by the Biostrings package
+and derives the @code{DotBracketString} and related classes from the BString
+class.  From these, base pair tables can be produced for in depth analysis.
+In addition, the loop indices of the base pairs can be retrieved as well.  For
+better efficiency, information conversion is implemented in C, inspired to a
+large extend by the @code{ViennaRNA} package.")
