+
+;; 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
