% 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.

% or in percent of \hsize, the current width of text on page.

%
|

% Either define widths of columns in terms of percent of \hsize:
|
||
% @multitable @columnfractions .25 .3 .45
|
||
% @item ...

||
% Or use a template:
|

% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
|

% @item ...
|
||
% using the widest term desired in each column.
|

% starts with @tab. Empty columns may be produced by supplying @tab's
|

% ie, @tab@tab@tab will produce two empty columns.

ERROR: A sorted index file in an obsolete format was skipped.
|

To fix this problem, please upgrade your version of 'texi2dvi'
|
||
or 'texi2pdf' to that at <https://ftp.gnu.org/gnu/texinfo>.
|
||
If you are using an old version of 'texindex' (part of the Texinfo
|

distribution), you may also need to upgrade to a newer version (at least 6.0).
|
||
You may be able to typeset the index if you run
|
||
'texindex \jobname.\indexname' yourself.
|
||
You could also try setting the 'txiindexescapeisbackslash' flag by
|
||
running a command like
|
||
'texi2dvi -t "@set txiindexescapeisbackslash" \jobname.texi'. If you do
|
||
this, Texinfo will try to use index files in the old format.
|

If you continue to have problems, deleting the index files and starting again
|

might help (with 'rm \jobname.?? \jobname.??s')%
