1886 ;; onto the `texinfo-stack'. At the @end multitable command, the stack
1887 ;; is checked for its matching @multitable command, and then popped, or
1888 ;; else an error is signaled. Also, this command pushes the location of
1889 ;; the start of the table onto the stack.
1891 ;; `texinfo-end-multitable' checks the `texinfo-stack' that the @end
1892 ;; multitable truly is ending a corresponding beginning, and if it is,
1893 ;; pops the stack.
1895 ;; `texinfo-multitable-widths' is called by `texinfo-multitable'.
1896 ;; The function returns a list of the widths of each column in a
1897 ;; multi-column table, based on the information supplied by the arguments
1898 ;; to the @multitable command (by arguments, I mean the text on the rest
1899 ;; of the @multitable line, not the remainder of the multi-column table
1900 ;; environment).
1902 ;; `texinfo-multitable-item' formats a row within a multicolumn table.
1903 ;; This command is executed when texinfmt sees @item inside @multitable.
1904 ;; Cells in row are separated by `@tab's. Widths of cells are specified
1905 ;; by the arguments in the @multitable line. Cells are filled. All cells
1906 ;; are made to be the same height by padding their bottoms, as needed,
1907 ;; with blanks.
1909 ;; `texinfo-multitable-extract-row' is called by `texinfo-multitable-item'.

2327 ;; A `@definfoenclose' command may be used to define a highlighting
2328 ;; command for Info, but not for TeX. A command defined using
2329 ;; `@definfoenclose' marks text by enclosing it in strings that precede
2330 ;; and follow the text.
2332 ;; Presumably, if you define a command with `@definfoenclose` for Info,
2333 ;; you will also define the same command in the TeX definitions file,
2334 ;; `texinfo.tex' in a manner appropriate for typesetting.
2336 ;; Write a `@definfoenclose' command on a line and follow it with three
2337 ;; arguments separated by commas (commas are used as separators in an
2338 ;; `@node' line in the same way). The first argument to
2339 ;; `@definfoenclose' is the @-command name (without the `@'); the
2340 ;; second argument is the Info start delimiter string; and the third
2341 ;; argument is the Info end delimiter string. The latter two arguments
2342 ;; enclose the highlighted text in the Info file. A delimiter string
2343 ;; may contain spaces. Neither the start nor end delimiter is
2344 ;; required. However, if you do not provide a start delimiter, you
2345 ;; must follow the command name with two commas in a row; otherwise,
2346 ;; the Info formatting commands will misinterpret the end delimiter
2347 ;; string as a start delimiter string.
2349 ;; If you do a @definfoenclose{} on the name of a pre-defined macro (such
2350 ;; as @emph{}, @strong{}, @tt{}, or @i{}) the enclosure definition will
2351 ;; override the built-in definition.
2353 ;; An enclosure command defined this way takes one argument in braces.
2355 ;; For example, you can write:
2357 ;; @ifinfo
2358 ;; @definfoenclose phoo, //, \\
2359 ;; @end ifinfo
2361 ;; near the beginning of a Texinfo file at the beginning of the lines
2362 ;; to define `@phoo' as an Info formatting command that inserts `//'
2363 ;; before and `\\' after the argument to `@phoo'. You can then write
2364 ;; `@phoo{bar}' wherever you want `//bar\\' highlighted in Info.
2366 ;; Also, for TeX formatting, you could write
2368 ;; @iftex
2369 ;; @global@let@phoo=@i
2370 ;; @end iftex
2372 ;; to define `@phoo' as a command that causes TeX to typeset
2373 ;; the argument to `@phoo' in italics.
2375 ;; Note that each definition applies to its own formatter: one for TeX,
2376 ;; the other for texinfo-format-buffer or texinfo-format-region.
2378 ;; Here is another example: write
2380 ;; @definfoenclose headword, , :
2382 ;; near the beginning of the file, to define `@headword' as an Info
2383 ;; formatting command that inserts nothing before and a colon after the

4087 ;; incorporated in to the printed manual. To make references to the
4088 ;; included file, the Texinfo source file has to refer to the included
4089 ;; files using the `(filename)nodename' format for referring to other
4090 ;; Info files. Also, the included files had to be formatted on their
4091 ;; own. It was just like they were another file.
4093 ;; Currently, include files are inserted into the buffer that is
4094 ;; formatted for Info. If large, the resulting info file is split and
4095 ;; tagified. For current include files to work, the master menu must
4096 ;; refer to all the nodes, and the highest level nodes in the include
4097 ;; files must have the correct next, prev, and up pointers.
4099 ;; The included file may have an @setfilename and even an @settitle,
4100 ;; but not an `\input texinfo' line.
4102 ;; Updated 24 March 1993
4103 ;; In order for @raisesections and @lowersections to work, included
4104 ;; files must be inserted into the buffer holding the outer file
4105 ;; before other Info formatting takes place. So @include is no longer
