This can be worked around if you have code sections that don't change
at all, put them in a separate file and import them into the "main"
LaTeX document using '\input'. Then use the Makefile to specify the
dependencies between the LaTeX files. That way, when you run make the
first time, everything will run, but on subsequent calls to make,
Sweave will not be called as long as the code in the separate file
hasn't changed.

I don't think I've used postscript in about 8 years.
