+% @multitable macros
+% Amy Hendrickson, 8/18/94
+%
+% @multitable ... @endmultitable 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 @percentofhsize .2 .3 .5
+% @item ...
+%
+% Numbers following @percentofhsize 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, @multicolumn or @endmulticolumn 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.
+% @endmultitable
+
+% Default dimensions may be reset by user.
+% @intableparskip will set vertical space between paragraphs in table.
+% @intableparindent will set paragraph indent in table.
+% @spacebetweencols will set horizontal space to be left between columns.
+% @spacebetweenlines will set vertical space to be left between lines.
