plot
+in publication quality.  @code{ggVennDiagram} plot Venn using well-defined 
geometry
+dataset and @code{ggplot2}.  The shapes of 2-4 sets Venn use circles and 
ellipses,
+while the shapes of 4-7 sets Venn use irregular polygons (4 has both forms), 
which
+are developed and imported from another package @code{venn}.  We provide 
internal
+functions to integrate shape data with user provided sets data, and calculated
+the geometry of every regions/intersections of them, then separately plot Venn
+in three components: set edges, set labels, and regions.  From version 1.0, it
+is possible to customize these components as you demand in ordinary 
@code{ggplot2}
+grammar.")
