Yup. But it's tricky. 'rcpp.package.skeleton()' also works without modules,
and existed before modules were added, so this may be the best compromise.

Suggestions (patches even !!) for clearer documentations are always appreciated.

Yes, that was something John Chambers changed in the R (and then the Rcpp
guts) not quite year ago.  It is better now, but it required a change.

:)

There are some limites to modules (no load/save across sessions as we can't
ensure the memory location, no multiple inheritance) but for many things it
is indeed pretty peachy.

Glad it is all working for you.
