                     43: % To process a Texinfo manual with TeX, it's most reliable to use the

                     45: % manual foo.texi, however, you can get away with this:
                     46: %   tex foo.texi

                     50: %   dvips foo.dvi -o  # or whatever; this makes foo.ps.
                     51: % The extra TeX runs get the cross-reference information correct.
                     52: % Sometimes one run after texindex suffices, and sometimes you need more
                     53: % than two; texi2dvi does it as many times as necessary.
