But this is a matter of how you do the installation. If you install
directly from the development directory and don't clean the object
R CMD INSTALL ~/Rpkgs/myPackage
then only the changed source files will be recompiled. I prefer not
to do this because I don't want object files left lying around but
then I don't have 100 source files in any of my packages.
