;;
;; in an org-mode buffer then switch to the buffer to see the HTML
;; export. See contrib/lisp/org-export.el for more details on how

;; It introduces three new buffer keywords: "LATEX_CLASS",

"Alist of HTML classes and associated header and structure.
If #+HTML_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
HTML 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-export-latex-default-packages-alist' and
`org-export-latex-packages-alist'. Thus, your header
definitions should avoid to also request these packages.
- Lines specified via \"#+HTML_HEADER:\"
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 #+HTML_HEADER
[NO-EXTRA] do not include #+HTML_HEADER stuff
[BEAMER-HEADER-EXTRA] the beamer extra headers
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
#+HTML_HEADER lines, then have a call to \\providecommand, and
then place \\usepackage commands based on the content of
`org-export-latex-packages-alist'.
If your header, `org-export-latex-default-packages-alist' or
`org-export-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-e-html-inputenc-alist' for a way to influence this
mechanism.
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 HTML 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
