+% Texinfo macros (with @macro) are *not* supported by texinfo.tex. You
+% have to run makeinfo -E to expand macros first; the texi2dvi script
+% does this.
+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution. For simple
+% manuals, you can get away with:
+% tex foo.texi
+% texindex foo.??
+% tex foo.texi
+% tex foo.texi
+% dvips foo.dvi -o # or whatever, to process the dvi file.
+% The extra runs of TeX get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
