+% Please try the latest version of texinfo.tex before submitting bug
+% reports; you can get the latest version from:
+% ftp://ftp.gnu.org/gnu/texinfo.tex
+% (and all GNU mirrors, see http://www.gnu.org/order/ftp.html)
+% ftp://texinfo.org/tex/texinfo.tex
+% ftp://us.ctan.org/macros/texinfo/texinfo.tex
+% (and all CTAN mirrors, finger ctan@us.ctan.org for a list).
+% /home/gd/gnu/doc/texinfo.tex on the GNU machines.
+% The texinfo.tex in any given Texinfo distribution could well be out
+% of date, so if that's what you're using, please check.
+% Texinfo has a small home page at http://texinfo.org/.
+%
+% Send bug reports to bug-texinfo@gnu.org. Please include including a
+% complete document in each bug report with which we can reproduce the
+% problem. Patches are, of course, greatly appreciated.
+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution. For a simple
+% manual foo.texi, however, you can get away with this:
+% tex foo.texi
+% texindex foo.??
+% tex foo.texi
+% tex foo.texi
+% dvips foo.dvi -o # or whatever, to process the dvi file; this makes foo.ps.
+% 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.
+%
+% It is possible to adapt texinfo.tex for other languages. You can get
+% the existing language-specific files from ftp://ftp.gnu.org/gnu/texinfo/.
