[R] cacheSweave / pgfSweave driver for package vignette

[Romain Francois]

Hi,

I've been meaning to ask the same question before.

This is what we do in Rcpp to build our 7 vignettes (since we like to 
use the driver from highlight).

One thing to have in mind is that R needs the .Rnw file to be present in 
doc once the package is installed, so that the vignette function works, 
hence some trickery in Rcpp.

A way to control which sweave (and perhaps tangle) driver is to be used 
for a particular vignette would be very useful.
