It is a regular expression that basically says "export all the things", meaning the functions provided by your package. I regard it as a placeholder to make things work temporarily, while you get yourself organized for more proactive management of NAMESPACE.

I don't feel like you'll ever see that combined with import directives (as you have below), once you really begin to use roxygen? 

You should put 
#' @export
directives in the roxygen header of every function that should be exported and they will appear in NAMESPACE individually after you roxygenize or run devtools::document().

Somewhere you will also need import directives corresponding to all those imports you want to do. They can go in any roxygen header.
