+mapped back and forth to C++ equivalents which facilitates both writing of new
+code as well as easier integration of third-party libraries.  Documentation
+about Rcpp is provided by several vignettes included in this package, via the
+'Rcpp Gallery' site at <http://gallery.rcpp.org>, the paper by Eddelbuettel
+and Francois (2011, JSS), and the book by Eddelbuettel (2013, Springer); see
+'citation(\"Rcpp\")' for details on these last two.")
