 \description{
-  \code{LdFlags} and \code{RcppLdFlags} return the required flags and
-  options for the system linker. This allows portable use of
-  \pkg{Rcpp} as package location as well as operating-system specific
-  details are abstracted away behind the interface of this function.
-
-  \code{LdFlags} is commonly called from the files \code{Makevars} (or
-  \code{Makevars.win}) rather than in an interactive session.
+  In previous versions of Rcpp, \code{LdFlags} and \code{RcppLdFlags}  
+  were used to return the required flags and options for the system linker to 
+  link to the Rcpp user library. Since we no longer build or ship a 
+  user library, these functions now return an empty string.
 }
 \usage{

-}
-\details{
-  Thee functions are not meant to used interactively, and are intended
-  solely for use by the build tools.
+  An empty string.
