In this directory you can find the stuff necessary for building RWEB, the REDUCE version of SPIDERY WEB. Along with these files you need a version of SPIDERY WEB, which can be obtained by anonymous ftp from princeton.edu (128.112.128.1). After you have installed SPIDERY WEB you know what it means to put the files contained in this directory into a new directory $(WEBROOT)/reduce. Do it. You might as well want to change the variable HOME in $(WEBROOT)/reduce/Makefile (which is in fact an adapted version of $(MASTER)/WebMakefile). In order to make RWEB, go to $(WEBROOT)/reduce and type 'make weave', 'make tangle' or 'make web', if you want to make rweave, rtangle or both. The documentation needed for using RWEB is $(WEBROOT)/doc/spiderwebman.tex. Have fun, Marcel Roelofs, University of Twente, Department of applied mathematics, P.O.
