--%
--% Please try the latest version of texinfo.tex before submitting bug

--% 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.

--% @multitable macros
--% 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 at 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 at 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
--%                                                            to baseline.
