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.
