|  | % 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; this makes foo.ps.
 | |||
|  | % The extra TeX runs 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, to some
 | |||
|  | % extent.  You can get the existing language-specific files from the
 | |||
|  | % full Texinfo distribution.
