+     "This package provides facilities for reading various formats used to
+store snapshots, group catalogues and merger trees in Virgo Consortium
+simulations, including older binary formats which can otherwise be difficult
+to deal with.
+
+It also provides a collection of MPI parallel algorithms which can be useful
+for dealing with particle data and a few related utility functions.")
