26 % a Texinfo source document, you may use the result without
27 % restriction. (This has been our intent since Texinfo was invented.)
29 % Please try the latest version of texinfo.tex before submitting bug
30 % reports; you can get the latest version from:
31 % http://www.gnu.org/software/texinfo/ (the Texinfo home page), or
32 % ftp://tug.org/tex/texinfo.tex
33 % (and all CTAN mirrors, see http://www.ctan.org).
34 % The texinfo.tex in any given distribution could well be out
35 % of date, so if that's what you're using, please check.
37 % Send bug reports to bug-texinfo@gnu.org. Please include including a
38 % complete document in each bug report with which we can reproduce the
39 % problem. Patches are, of course, greatly appreciated.
41 % To process a Texinfo manual with TeX, it's most reliable to use the
42 % texi2dvi shell script that comes with the distribution. For a simple
43 % manual foo.texi, however, you can get away with this:
44 % tex foo.texi
45 % texindex foo.??
46 % tex foo.texi
47 % tex foo.texi
48 % dvips foo.dvi -o # or whatever; this makes foo.ps.
49 % The extra TeX runs get the cross-reference information correct.
50 % Sometimes one run after texindex suffices, and sometimes you need more
51 % than two; texi2dvi does it as many times as necessary.
53 % It is possible to adapt texinfo.tex for other languages, to some
54 % extent. You can get the existing language-specific files from the
55 % full Texinfo distribution.
57 % The GNU Texinfo home page is http://www.gnu.org/software/texinfo.

3328 % @multitable ... @end multitable will make as many columns as desired.
3329 % Contents of each column will wrap at width given in preamble. Width
3330 % can be specified either with sample text given in a template line,
3331 % or in percent of \hsize, the current width of text on page.
3333 % Table can continue over pages but will only break between lines.
3335 % To make preamble:
3337 % Either define widths of columns in terms of percent of \hsize:
3338 % @multitable @columnfractions .25 .3 .45
3339 % @item ...
3341 % Numbers following @columnfractions are the percent of the total
3342 % current hsize to be used for each column. You may use as many
3343 % columns as desired.
3346 % Or use a template:
3347 % @multitable {Column 1 template} {Column 2 template} {Column 3 template}
3348 % @item ...
3349 % using the widest term desired in each column.
3351 % Each new table line starts with @item, each subsequent new column
3352 % starts with @tab. Empty columns may be produced by supplying @tab's
3353 % with nothing between them for as many times as empty columns are needed,
3354 % ie, @tab@tab@tab will produce two empty columns.
3356 % @item, @tab do not need to be on their own lines, but it will not hurt
3357 % if they are.

3361 % @multitable {Column 1 template} {Column 2 template} {Column 3 template}

3365 % @tab
3366 % second col stuff
3367 % @tab
3368 % third col
3369 % @item first col stuff @tab second col stuff
3370 % @tab Many paragraphs of text may be used in any column.

3373 % @item@tab@tab This will be in third column.
3374 % @end multitable
