+ (description
+ "The R @code{XNAString} package allows for description of base sequences
+and associated chemical modifications in a single object. XNAString is able to
+capture single stranded, as well as double stranded molecules. Chemical
+modifications are represented as independent strings associated with different
+features of the molecules (base sequence, sugar sequence, backbone sequence,
+modifications) and can be read or written to a @dfn{Hierarchical Editing
+Language for Macromolecules} (HELM) notation. It also enables secondary
+structure prediction using RNAfold from ViennaRNA. XNAString is designed to be
+efficient representation of nucleic-acid based therapeutics, therefore it
+stores information about target sequences and provides interface for matching
+and alignment functions from Biostrings package.")
