"Alist of LaTeX classes and associated header and structure.
If #+LATEX_CLASS is set in the buffer, use its value and the
associated information. Here is the structure of each cell:
\(class-name
header-string
\(numbered-section . unnumbered-section)
...)
The header string
-----------------
The HEADER-STRING is the header that will be inserted into the
LaTeX file. It should contain the \\documentclass macro, and
anything else that is needed for this setup. To this header, the
following commands will be added:
- Calls to \\usepackage for all packages mentioned in the
variables `org-latex-default-packages-alist' and
`org-latex-packages-alist'. Thus, your header definitions
should avoid to also request these packages.
- Lines specified via \"#+LATEX_HEADER:\" and
\"#+LATEX_HEADER_EXTRA:\" keywords.
If you need more control about the sequence in which the header
is built up, or if you want to exclude one of these building
blocks for a particular class, you can use the following
macro-like placeholders.
[DEFAULT-PACKAGES] \\usepackage statements for default packages
[NO-DEFAULT-PACKAGES] do not include any of the default packages
[PACKAGES] \\usepackage statements for packages
[NO-PACKAGES] do not include the packages
[EXTRA] the stuff from #+LATEX_HEADER(_EXTRA)
[NO-EXTRA] do not include #+LATEX_HEADER(_EXTRA) stuff
So a header like
\\documentclass{article}
[NO-DEFAULT-PACKAGES]
[EXTRA]
\\providecommand{\\alert}[1]{\\textbf{#1}}
[PACKAGES]
will omit the default packages, and will include the
#+LATEX_HEADER and #+LATEX_HEADER_EXTRA lines, then have a call
to \\providecommand, and then place \\usepackage commands based
on the content of `org-latex-packages-alist'.
If your header, `org-latex-default-packages-alist' or
`org-latex-packages-alist' inserts \"\\usepackage[AUTO]{inputenc}\",
AUTO will automatically be replaced with a coding system derived
from `buffer-file-coding-system'. See also the variable
`org-latex-inputenc-alist' for a way to influence this mechanism.
Likewise, if your header contains \"\\usepackage[AUTO]{babel}\",
AUTO will be replaced with the language related to the language
code specified by `org-export-default-language', which see. Note
that constructions such as \"\\usepackage[french,AUTO,english]{babel}\"
are permitted.
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 cons cell (numbered . unnumbered), you can also
provide a list of 2 or 4 elements,
\(numbered-open numbered-close)
or
\(numbered-open numbered-close unnumbered-open unnumbered-close)
providing opening and closing strings for a LaTeX environment
that should represent the document section. The opening clause
should have a %s to represent the section title.
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."

The reason why this is a list is that it usually takes several
runs of `pdflatex', maybe mixed with a call to `bibtex'. Org
does not have a clever mechanism to detect which of these
commands have to be run to get to a stable result, and it also
does not do any error checking.
By default, Org uses 3 runs of `pdflatex' to do the processing.

the infamous egrep/locale bug:
http://lists.gnu.org/archive/html/bug-texinfo/2010-03/msg00031.html
then `texi2dvi' is the superior choice as it automates the LaTeX
build process by calling the \"correct\" combinations of
auxiliary programs. Org does offer `texi2dvi' as one of the
customize options. Alternatively, `rubber' and `latexmk' also
provide similar functionality. The latter supports `biber' out
of the box.
Alternatively, this may be a Lisp function that does the
processing, so you could use this to apply the machinery of
AUCTeX or the Emacs LaTeX mode. This function should accept the
file name as its single argument."
