It is indeed intended to streamline how package developers work. With
compileAttributes you only need to create cpp files that contain function
definitions marked with Rcpp::export attributes (you don't need to write
any explicit code in .h or .R files, this code is generated by
compileAttributes).

If you pull the latest Rpp from R-forge  you'll find:

(a) An expanded vignette which goes into more details about the whole
mechanism (especially as it relates to packages).

(b) An updated version of Rcpp.package.skeleton which you can optionally
pass a parameter of attributes = TRUE to see what hello, world using
attributes looks like.
