38 % problem. Patches are, of course, greatly appreciated.
40 % To process a Texinfo manual with TeX, it's most reliable to use the
41 % texi2dvi shell script that comes with the distribution. For a simple
42 % manual foo.texi, however, you can get away with this:
47 % dvips foo.dvi -o # or whatever; this makes foo.ps.
48 % The extra TeX runs get the cross-reference information correct.
49 % Sometimes one run after texindex suffices, and sometimes you need more
50 % than two; texi2dvi does it as many times as necessary.
52 % It is possible to adapt texinfo.tex for other languages, to some
53 % extent. You can get the existing language-specific files from the
54 % full Texinfo distribution.

5450 ERROR: A sorted index file in an obsolete format was skipped.
5451 To fix this problem, please upgrade your version of 'texi2dvi'
5452 or 'texi2pdf' to that at <https://ftp.gnu.org/gnu/texinfo>.
5453 If you are using an old version of 'texindex' (part of the Texinfo
5454 distribution), you may also need to upgrade to a newer version (at least
6.0).
5455 You may be able to typeset the index if you run
5456 'texindex
\jobname.
\indexname' yourself.
5457 You could also try setting the 'txiindexescapeisbackslash' flag by
5458 running a command like
5459 'texi2dvi -t "@set txiindexescapeisbackslash"
\jobname.texi'. If you do
5460 this, Texinfo will try to use index files in the old format.
5461 If you continue to have problems, deleting the index files and starting again
5462 might help (with 'rm
