+What a Texinfo File Must Have
+=============================
+
+ By convention, the names of Texinfo files end with one of the
+extensions `.texinfo', `.texi', or `.tex'. The longer extension is
+preferred since it describes more clearly to a human reader the nature
+of the file. The shorter extensions are for operating systems that
+cannot handle long file names.
+
+ In order to be made into a printed manual and an Info file, a Texinfo
+file *must* begin with lines like this:
+
+ \input texinfo
+ @setfilename INFO-FILE-NAME
+ @settitle NAME-OF-MANUAL
+
+The contents of the file follow this beginning, and then you *must* end
+a Texinfo file with a line like this:
+
+ @bye
+
+The `\input texinfo' line tells TeX to use the `texinfo.tex' file,
+which tells TeX how to translate the Texinfo @-commands into TeX
+typesetting commands. (Note the use of the backslash, `\'; this is
+correct for TeX.) The `@setfilename' line provides a name for the Info
+file and tells TeX to open auxiliary files. The `@settitle' line
+specifies a title for the page headers (or footers) of the printed
+manual.
+
+ The `@bye' line at the end of the file on a line of its own tells the
+formatters that the file is ended and to stop formatting.
+
+ Usually, you will not use quite such a spare format, but will include
+mode setting and start-of-header and end-of-header lines at the
+beginning of a Texinfo file, like this:
+
+ \input texinfo @c -*-texinfo-*-
+ @c %**start of header
+ @setfilename INFO-FILE-NAME
+ @settitle NAME-OF-MANUAL
+ @c %**end of header
+
+In the first line, `-*-texinfo-*-' causes Emacs to switch into Texinfo
+mode when you edit the file.
+
+ The `@c' lines which surround the `@setfilename' and `@settitle'
+lines are optional, but you need them in order to run TeX or Info on
+just part of the file. (*Note Start of Header::, for more information.)
+
+ Furthermore, you will usually provide a Texinfo file with a title
+page, indices, and the like. But the minimum, which can be useful for
+short documents, is just the three lines at the beginning and the one
+line at the end.

+Six Parts of a Texinfo File
+===========================
+
+ Generally, a Texinfo file contains more than the minimal beginning
+and end--it usually contains six parts:
+
+1. Header
+ The "Header" names the file, tells TeX which definitions' file to
+ use, and performs other "housekeeping" tasks.
+
+2. Summary Description and Copyright
+ The "Summary Description and Copyright" segment describes the
+ document and contains the copyright notice and copying permissions
+ for the Info file. The segment must be enclosed between `@ifinfo'
+ and `@end ifinfo' commands so that the formatters place it only in
+ the Info file.
+
+3. Title and Copyright
+ The "Title and Copyright" segment contains the title and copyright
+ pages and copying permissions for the printed manual. The segment
+ must be enclosed between `@titlepage' and `@end titlepage'
+ commands. The title and copyright page appear only in the printed
+ manual.
+
+4. `Top' Node and Master Menu
+ The "Master Menu" contains a complete menu of all the nodes in the
+ whole Info file. It appears only in the Info file, in the `Top'
+ node.
+
+5. Body
+ The "Body" of the document may be structured like a traditional
+ book or encyclopedia or it may be free form.
+
+6. End
+ The "End" contains commands for printing indices and generating
+ the table of contents, and the `@bye' command on a line of its own.
+
