+Create a skeleton for a new package depending on Rcpp

+\description{
+ \code{cpp.package.skeleton} automates the creation of
+ a new source package that intends to use features of Rcpp.
+
+ It is based on the \link[utils]{package.skeleton} function
+ which it executes first.
+}

+\details{
+ In addition to \link[utils]{package.skeleton} :
+
+ The \samp{DESCRIPTION} file gains a Depends line requesting that
+ the package depends on Rcpp
+
+ The \samp{NAMESPACE}, if any, gains a \code{useDynLib} directove
+
+ The \samp{src} directory is created if it does not exists and
+ a \samp{Makevars} file is added setting the environment variables
+ \samp{PKG_CXXFLAGS} and \samp{PKG_LIBS}
