+     "This package provides a graph implementation that can be thought of as
+two tidy data frames describing node and edge data respectively.  It provides
+an approach to manipulate these two virtual data frames using the API defined
+in the @code{dplyr} package, and it also provides tidy interfaces to a lot of
+common graph algorithms.")
