The header string
-----------------
The header string is inserted in the header of the generated
document, right after \"@setfilename\" and \"@settitle\"
commands.
If it contains the special string
\"@documentencoding AUTO\"
\"AUTO\" will be replaced with an appropriate coding system. See
`org-texinfo-coding-system' for more information. Likewise, if
the string contains the special string
\"@documentlanguage AUTO\"
\"AUTO\" will be replaced with the language defined in the
buffer, through #+LANGUAGE keyword, or globally, with
`org-export-default-language', which see.
The sectioning structure
------------------------
The sectioning structure of the class is given by the elements
following the header string. For each sectioning level, a number
of strings is specified. A %s formatter is mandatory in each
section string and will be replaced by the title of the section.
Instead of a list of sectioning commands, you can also specify
a function name. That function will be called with two
parameters, the reduced) level of the headline, and a predicate
non-nil when the headline should be numbered. It must return
a format string in which the section title will be added."
