Latex files created by the noweave command will contain the line
usepackage{noweb}, which in turn will try to load the file
noweb.sty. A copy of this file needs to be either in the local
directory or on the search path used by Latex.
This data set is a copy of the file; create a disk copy for Latex by
using write(noweb.sty, file="noweb.sty").
