+     "@dfn{AS} (alternative splicing) is a common mechanism of
+post-transcriptional gene regulation in eukaryotic organisms that expands the
+functional and regulatory diversity of a single gene by generating multiple
+mRNA isoforms that encode structurally and functionally distinct proteins.
+ASpli is an integrative pipeline and user-friendly R package that facilitates
+the analysis of changes in both annotated and novel AS events.  ASpli
+integrates several independent signals in order to deal with the complexity
+that might arise in splicing patterns.")
