;; process included files: `@include' command
;; Updated 19 October 1990
;; In the original version, include files were ignored by Info but
;; incorporated in to the printed manual. To make references to the
;; included file, the Texinfo source file has to refer to the included
;; files using the `(filename)nodename' format for refering to other
;; Info files. Also, the included files had to be formatted on their
;; own. It was just like they were another file.
;; Currently, include files are inserted into the buffer that is
;; formatted for Info. If large, the resulting info file is split and
;; tagified. For current include files to work, the master menu must
;; refer to all the nodes, and the highest level nodes in the include
;; files must have the correct next, prev, and up pointers.
;; The included file may have an @setfilename and even an @settitle,
;; but not an /input texinfo
