[Rcpp-devel] How to manage testing code for Rcpp based project?

The development version of devtools now attempts to compile C, C++ and
fortran code in your src/ directory, and then dynamically link into
your running R session (thanks to hard work by Winston Chang).  It's
unlikely to be perfect (or to work for large, complicated projects),
but it's a step forward, and should be useful if you only have a few
c++ files.

(Note that this of course doesn't reduce the time needed to compile
the files, but it does substantially reduce the amount of time needed
to install the package)
