1882 ;; =====================
1884 ;; `texinfo-multitable' reads the @multitable line and determines from it
1885 ;; how wide each column should be.
1887 ;; Also, it pushes this information, along with an identifying symbol,
1888 ;; onto the `texinfo-stack'. At the @end multitable command, the stack
1889 ;; is checked for its matching @multitable command, and then popped, or
1890 ;; else an error is signaled. Also, this command pushes the location of
1891 ;; the start of the table onto the stack.
1893 ;; `texinfo-end-multitable' checks the `texinfo-stack' that the @end
1894 ;; multitable truly is ending a corresponding beginning, and if it is,
1897 ;; `texinfo-multitable-widths' is called by `texinfo-multitable'.
1898 ;; The function returns a list of the widths of each column in a
1899 ;; multi-column table, based on the information supplied by the arguments
1900 ;; to the @multitable command (by arguments, I mean the text on the rest
1901 ;; of the @multitable line, not the remainder of the multi-column table
1904 ;; `texinfo-multitable-item' formats a row within a multicolumn table.
1905 ;; This command is executed when texinfmt sees @item inside @multitable.
1906 ;; Cells in row are separated by `@tab's. Widths of cells are specified
1907 ;; by the arguments in the @multitable line. Cells are filled. All cells
1908 ;; are made to be the same height by padding their bottoms, as needed,
1911 ;; `texinfo-multitable-extract-row' is called by `texinfo-multitable-item'.
1912 ;; This function returns the text in a multitable row, as a string.
1913 ;; The start of a row is marked by an @item and the end of row is the
1914 ;; beginning of next @item or beginning of the @end multitable line.
1915 ;; Cells within a row are separated by @tab.
1917 ;; Note that @tab, the cell separators, are not treated as independent

2332 ;; and follow the text.
2334 ;; Presumably, if you define a command with `@definfoenclose` for Info,
2335 ;; you will also define the same command in the TeX definitions file,
2336 ;; `texinfo.tex' in a manner appropriate for typesetting.
2338 ;; Write a `@definfoenclose' command on a line and follow it with three
2339 ;; arguments separated by commas (commas are used as separators in an
2340 ;; `@node' line in the same way). The first argument to
2341 ;; `@definfoenclose' is the @-command name \(without the `@'\); the
2342 ;; second argument is the Info start delimiter string; and the third
2343 ;; argument is the Info end delimiter string. The latter two arguments
2344 ;; enclose the highlighted text in the Info file. A delimiter string
2345 ;; may contain spaces. Neither the start nor end delimiter is
2346 ;; required. However, if you do not provide a start delimiter, you
2347 ;; must follow the command name with two commas in a row; otherwise,
2348 ;; the Info formatting commands will misinterpret the end delimiter
2349 ;; string as a start delimiter string.
2351 ;; If you do a @definfoenclose{} on the name of a pre-defined macro (such
2352 ;; as @emph{}, @strong{}, @tt{}, or @i{}) the enclosure definition will
2353 ;; override the built-in definition.
2355 ;; An enclosure command defined this way takes one argument in braces.
2357 ;; For example, you can write:
2360 ;; @definfoenclose phoo, //, \\
2363 ;; near the beginning of a Texinfo file at the beginning of the lines
2364 ;; to define `@phoo' as an Info formatting command that inserts `//'
2365 ;; before and `\\' after the argument to `@phoo'. You can then write
2366 ;; `@phoo{bar}' wherever you want `//bar\\' highlighted in Info.

2371 ;; @global@let@phoo=@i
2374 ;; to define `@phoo' as a command that causes TeX to typeset
2375 ;; the argument to `@phoo' in italics.
2377 ;; Note that each definition applies to its own formatter: one for TeX,
2378 ;; the other for texinfo-format-buffer or texinfo-format-region.
2380 ;; Here is another example: write

4088 ;; In the original version, include files were ignored by Info but
4089 ;; incorporated in to the printed manual. To make references to the
4090 ;; included file, the Texinfo source file has to refer to the included
4091 ;; files using the `(filename)nodename' format for referring to other
4092 ;; Info files. Also, the included files had to be formatted on their
4093 ;; own. It was just like they were another file.
4095 ;; Currently, include files are inserted into the buffer that is
4096 ;; formatted for Info. If large, the resulting info file is split and
4097 ;; tagified. For current include files to work, the master menu must
4098 ;; refer to all the nodes, and the highest level nodes in the include
4099 ;; files must have the correct next, prev, and up pointers.
4101 ;; The included file may have an @setfilename and even an @settitle,
4102 ;; but not an `\input texinfo' line.
4104 ;; Updated 24 March 1993
4105 ;; In order for @raisesections and @lowersections to work, included
4106 ;; files must be inserted into the buffer holding the outer file
4107 ;; before other Info formatting takes place. So @include is no longer
4108 ;; is treated like other @-commands.
