+     "This is a package for graphical and statistical analyses of
+environmental data, with a focus on analyzing chemical concentrations and
+physical parameters, usually in the context of mandated environmental
+monitoring.  It provides major environmental statistical methods found in the
+literature and regulatory guidance documents, with extensive help that
+explains what these methods do, how to use them, and where to find them in the
+literature.  It comes with numerous built-in data sets from regulatory
+guidance documents and environmental statistics literature.  It includes
+scripts reproducing analyses presented in the book \"EnvStats: An R Package
+for Environmental Statistics\" (Millard, 2013, Springer, ISBN
