While we are on the subject of terminology, it is important to remember
that Rcpp is a C++ library, and this is often confused with Rcpp the
package. I changed the package name to limit confusion on this
point, but the package name was changed back to Rcpp for the "fork" (or
"branch", not sure what else to call it). The one constant in all of
this is Rcpp the C++ library.
