% 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.

% Amy Hendrickson, 8/18/94, 3/6/96
|
|
%
|
|
% @multitable ... @end multitable will make as many columns as desired.
|
|
% Contents of each column will wrap at width given in preamble. Width
|
|
% can be specified either with sample text given in a template line,
|
|
% or in percent of \hsize, the current width of text on page.
|
|
|
|
% Table can continue over pages but will only break between lines.
|
|
|
|
% To make preamble:
|
|
%
|
|
% Either define widths of columns in terms of percent of \hsize:
|
|
% @multitable @columnfractions .25 .3 .45
|
|
% @item ...
|
|
%
|
|
% Numbers following @columnfractions are the percent of the total
|
|
% current hsize to be used for each column. You may use as many
|
|
% columns as desired.
|
|
|
|
|
|
% Or use a template:
|
|
% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
|
|
% @item ...
|
|
% using the widest term desired in each column.
|
|
|
|
% Each new table line starts with @item, each subsequent new column
|
|
% starts with @tab. Empty columns may be produced by supplying @tab's
|
|
% with nothing between them for as many times as empty columns are needed,
|
|
% ie, @tab@tab@tab will produce two empty columns.
|
|
|
|
% @item, @tab do not need to be on their own lines, but it will not hurt
|
|
% if they are.
|
|
|
|
% Sample multitable:
|
|
|
|
% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
|
|
% @item first col stuff @tab second col stuff @tab third col
|
|
% @item
|
|
% first col stuff
|
|
% @tab
|
|
% second col stuff
|
|
% @tab
|
|
% third col
|
|
% @item first col stuff @tab second col stuff
|
|
% @tab Many paragraphs of text may be used in any column.
|
|
%
|
|
% They will wrap at the width determined by the template.
|
|
% @item@tab@tab This will be in third column.
|
|
% @end multitable
|
|
|
|
% Default dimensions may be reset by user.
|
|
% @multitableparskip is vertical space between paragraphs in table.
|
|
% @multitableparindent is paragraph indent in table.
|
|
% @multitablecolmargin is horizontal space to be left between columns.
|
|
% @multitablelinespace is space to leave between table items, baseline
