+     "Circular layout is an efficient way for the visualization of huge
+amounts of information.  This package provides an implementation of circular
+layout generation in R as well as an enhancement of available software.  The
+flexibility of the package is based on the usage of low-level graphics
+functions such that self-defined high-level graphics can be easily implemented
+by users for specific purposes.  Together with the seamless connection between
+the powerful computational and visual environment in R, it gives users more
+convenience and freedom to design figures for better understanding complex
+patterns behind multiple dimensional data.")
