12.11.2 Document preamble
-------------------------
When processing a document, ‘texinfo’ back-end generates a minimal file
header along with a title page, a copyright page, and a menu. You
control the latter through the structure of the document (Headings
and sectioning structure). Various keywords allow you to tweak the
other parts. It is also possible to give directions to install the
document in the ‘Top’ node.
File header
...........
Upon creating the header of a Texinfo file, the back-end guesses a name
for the Info file to be compiled. This may not be a sensible choice,
e.g., if you want to produce the final document in a different
directory. Specify an alternate path with ‘#+TEXINFO_FILENAME’ keyword
to override the default destination.
Along with the output file name, the header contains information
about the language (Export settings) and current encoding
used(1). Insert a ‘#+TEXINFO_HEADER’ keyword for each additional
command needed, e.g., @code{@synindex}.
If you happen to regularly install the same set of commands, it may
be easier to define your own class in ‘org-texinfo-classes’, which see.
Set ‘#+TEXINFO_CLASS’ keyword accordingly in your document to activate
it.
Title and copyright page
........................
The default template includes a title page for hard copy output. The
title and author displayed on this page are extracted from,
respectively, ‘#+TITLE’ and ‘#+AUTHOR’ keywords (Export
settings). It is also possible to print a different, more specific,
title with ‘#+TEXINFO_PRINTED_TITLE’ keyword, and add subtitles with
‘#+SUBTITLE’ keyword. Both expect raw Texinfo code in their value.
Likewise, information brought by ‘#+AUTHOR’ may not be enough. You
can include other authors with several ‘#+SUBAUTHOR’ keywords. Values
are also expected to be written in Texinfo code.
#+AUTHOR: Jane Smith
#+SUBAUTHOR: John Doe
#+TEXINFO_PRINTED_TITLE: This Long Title@inlinefmt{tex,@*} Is Broken in @TeX{}
Copying material is defined in a dedicated headline with a non-nil
‘:COPYING:’ property. The contents are inserted within a ‘@copying’
command at the beginning of the document whereas the heading itself does
not appear in the structure of the document.
Copyright information is printed on the back of the title page.

The Top node
............
You may ultimately want to install your new Info file to your system.
You can write an appropriate entry in the top level directory specifying
its category and title with, respectively, ‘#+TEXINFO_DIR_CATEGORY’ and
‘#+TEXINFO_DIR_TITLE’. Optionally, you can add a short description
using ‘#+TEXINFO_DIR_DESC’. The following example would write an entry
similar to Org’s in the ‘Top’ node.
#+TEXINFO_DIR_CATEGORY: Emacs
#+TEXINFO_DIR_TITLE: Org Mode: (org)
#+TEXINFO_DIR_DESC: Outline-based notes management and organizer
