-@item -O box[@var{line-type}]=@var{box-chars}
-Sets the characters used for lines in tables.  @var{line-type} is a
-4-digit number that indicates the type of line to change, in the order
-`right', `bottom', `left', `top'.  Each digit is 0 for ``no line'', 1
-for a single line, and 2 for a double line.  @var{box-chars} is the
-character or string of characters to use for this type of line.
-
-For example, @code{box[0101]="|"} sets @samp{|} as the character to
-use for a single-width vertical line, and @code{box[1100]="\xda"} sets
-@samp{"\xda"}, which on MS-DOS is suitable for the top-left corner of
-a box, as the character for the intersection of two single-width
-lines, one each from the right and bottom.
-
-The defaults use @samp{-}, @samp{|}, and @samp{+} for single-width
-lines and @samp{=} and @samp{#} for double-width lines.
