   % Please try the latest version of texinfo.tex before submitting bug
   % reports; you can get the latest version from:
   %   ftp://ftp.gnu.org/pub/gnu/texinfo.tex
   %   (and all GNU mirrors, see http://www.gnu.org/order/ftp.html)
   %   ftp://tug.org/tex/texinfo.tex
   %   ftp://ctan.org/macros/texinfo/texinfo.tex
   %   (and all CTAN mirrors, finger ctan@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.
   % There is a small home page for Texinfo 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/.
