The accompanying file, between "BODY" and "ENDBODY" (which you may receive in several separate email messages), is a plain TeX file. When TeX-ed, it automatically unfolds 6 postscript files containing figures. Then when the dvi file is printed, these postscript files are "included". In other words one can print this file in the manner usual for a plain TeX file. If you have difficulty with this file please contact either author (radin@math.utexas.edu or sadun@math.utexas.edu) to obtain separately the plain TeX text and postscript figure files. BODY
