[Rd] executable files R package

[William Dunlap]

If you put your prebuilt.exe into a directory under the
'source' package's inst directory, say yourPkg/inst/executables/win32,
then the installed package will have them in in
yourPkg/executables/win32 and the user (via code you
write, presumably) can get the full path to the executable
in the installed package with
  system.file(package="yourPkg", "executables", "win32", "prebuilt.exe").
Paste the output of that into the command given to system().
