If you have multiple Rnw files producing pdfs, and you only want some
of them to be run, you do the following.  Say we have
  big.Rnw (takes a long time to run)
  small.Rnw (is quick)
You run yourself big.Rnw and produce big.pdf.  Then you put
  small.Rnw in /vignettes
  big.Rnw and big.pdf in inst/doc
That way, big.Rnw will not get run.  And the package installation will
contain both Rnw files and pdf files for both vignettes.

Note that this only works if you have both a quick and a long
vignette.  If you only have big.Rnw and big.pdf in inst/doc and
nothing in vignettes, R would still run Sweave on big.Rnw.

I agree the section on this in R-exts is a bit opaque: "By default R
CMD build will run Sweave on all files in Sweave format in vignettes,
or if that does not exist, inst/doc (but not in sub-directories)."
(R-exts 1.4)
