;; @item B1 @tab B2 @tab B3
;; @item C1 @tab C2 @tab C3

;;
;; Long lines of text are filled within columns.
;;
;; Using the Emacs Lisp formatter, texinfmt.el,

;;
;; @multitableparskip,
;; @multitableparindent,
;; @multitablecolmargin,
;; @multitablelinespace.
;; How @multitable works.
;; =====================
;;
;; `texinfo-multitable' reads the @multitable line and determines from it
;; how wide each column should be.
;;
;; Also, it pushes this information, along with an identifying symbol,
;; onto the `texinfo-stack'. At the @end multitable command, the stack
;; is checked for its matching @multitable command, and then popped, or
;; else an error is signaled. Also, this command pushes the location of
;; the start of the table onto the stack.
;;
;; `texinfo-end-multitable' checks the `texinfo-stack' that the @end
;; multitable truly is ending a corresponding beginning, and if it is,
;; pops the stack.
;;
;; `texinfo-multitable-widths' is called by `texinfo-multitable'.
;; The function returns a list of the widths of each column in a
;; multi-column table, based on the information supplied by the arguments
;; to the @multitable command (by arguments, I mean the text on the rest
;; of the @multitable line, not the remainder of the multi-column table
;; environment).
;;
;; `texinfo-multitable-item' formats a row within a multicolumn table.
;; This command is executed when texinfmt sees @item inside @multitable.
;; Cells in row are separated by `@tab's. Widths of cells are specified
;; by the arguments in the @multitable line. Cells are filled. All cells
;; are made to be the same height by padding their bottoms, as needed,
;; with blanks.
;;
;; `texinfo-multitable-extract-row' is called by `texinfo-multitable-item'.
;; This function returns the text in a multitable row, as a string.
;; The start of a row is marked by an @item and the end of row is the
;; beginning of next @item or beginning of the @end multitable line.
;; Cells within a row are separated by @tab.
;;
;; Note that @tab, the cell separators, are not treated as independent
;; Texinfo commands.

;; A `@definfoenclose' command may be used to define a highlighting
;; command for Info, but not for TeX. A command defined using
;; `@definfoenclose' marks text by enclosing it in strings that precede
;; and follow the text.
;;
;; Presumably, if you define a command with `@definfoenclose` for Info,
;; you will also define the same command in the TeX definitions file,
;; `texinfo.tex' in a manner appropriate for typesetting.
;;
;; Write a `@definfoenclose' command on a line and follow it with three
;; arguments separated by commas (commas are used as separators in an
;; `@node' line in the same way). The first argument to
;; `@definfoenclose' is the @-command name \(without the `@'\); the
;; second argument is the Info start delimiter string; and the third
;; argument is the Info end delimiter string. The latter two arguments
;; enclose the highlighted text in the Info file. A delimiter string
;; may contain spaces. Neither the start nor end delimiter is
;; required. However, if you do not provide a start delimiter, you
;; must follow the command name with two commas in a row; otherwise,
;; the Info formatting commands will misinterpret the end delimiter
;; string as a start delimiter string.
;;
;; If you do a @definfoenclose{} on the name of a pre-defined macro (such
;; as @emph{}, @strong{}, @tt{}, or @i{}) the enclosure definition will
;; override the built-in definition.
;;
;; An enclosure command defined this way takes one argument in braces.
;;
;; For example, you can write:
;;
;; @ifinfo
;; @definfoenclose phoo, //, \\
;; @end ifinfo
;;
;; near the beginning of a Texinfo file at the beginning of the lines
;; to define `@phoo' as an Info formatting command that inserts `//'
;; before and `\\' after the argument to `@phoo'. You can then write
;; `@phoo{bar}' wherever you want `//bar\\' highlighted in Info.
;;
;; Also, for TeX formatting, you could write
;;
;; @iftex
;; @global@let@phoo=@i
;; @end iftex
;;
;; to define `@phoo' as a command that causes TeX to typeset
;; the argument to `@phoo' in italics.
;;
;; Note that each definition applies to its own formatter: one for TeX,
;; the other for texinfo-format-buffer or texinfo-format-region.
;;
;; Here is another example: write
;;
;; @definfoenclose headword, , :
;;
;; near the beginning of the file, to define `@headword' as an Info
;; formatting command that inserts nothing before and a colon after the
;; argument to `@headword'.
