207 If #+LaTeX_CLASS is set in the buffer, use its value and the
208 associated information. Here is the structure of each cell:
212 \(numbered-section . unnumbered-section\)
218 The HEADER-STRING is the header that will be inserted into the
219 LaTeX file. It should contain the \\documentclass macro, and
220 anything else that is needed for this setup. To this header, the
221 following commands will be added:
223 - Calls to \\usepackage for all packages mentioned in the
224 variables `org-export-latex-default-packages-alist' and
225 `org-export-latex-packages-alist'. Thus, your header
226 definitions should avoid to also request these packages.
228 - Lines specified via \"#+LaTeX_HEADER:\"
230 If you need more control about the sequence in which the header
231 is built up, or if you want to exclude one of these building
232 blocks for a particular class, you can use the following
233 macro-like placeholders.
235 [DEFAULT-PACKAGES] \\usepackage statements for default packages
236 [NO-DEFAULT-PACKAGES] do not include any of the default packages
237 [PACKAGES] \\usepackage statements for packages
238 [NO-PACKAGES] do not include the packages
239 [EXTRA] the stuff from #+LaTeX_HEADER
240 [NO-EXTRA] do not include #+LaTeX_HEADER stuff
244 \\documentclass{article}
245 [NO-DEFAULT-PACKAGES]
247 \\providecommand{\\alert}[1]{\\textbf{#1}}
250 will omit the default packages, and will include the
251 #+LaTeX_HEADER lines, then have a call to \\providecommand, and
252 then place \\usepackage commands based on the content of
253 `org-export-latex-packages-alist'.
255 If your header, `org-export-latex-default-packages-alist' or
256 `org-export-latex-packages-alist' inserts
257 \"\\usepackage[AUTO]{inputenc}\", AUTO will automatically be
258 replaced with a coding system derived from
259 `buffer-file-coding-system'. See also the variable
260 `org-e-latex-inputenc-alist' for a way to influence this
263 The sectioning structure
264 ------------------------
266 The sectioning structure of the class is given by the elements
267 following the header string. For each sectioning level, a number
268 of strings is specified. A %s formatter is mandatory in each
269 section string and will be replaced by the title of the section.
271 Instead of a cons cell \(numbered . unnumbered\), you can also
272 provide a list of 2 or 4 elements,
274 \(numbered-open numbered-close\)
278 \(numbered-open numbered-close unnumbered-open unnumbered-close\)
280 providing opening and closing strings for a LaTeX environment
281 that should represent the document section. The opening clause
282 should have a %s to represent the section title.
284 Instead of a list of sectioning commands, you can also specify
285 a function name. That function will be called with two
286 parameters, the \(reduced) level of the headline, and a predicate
287 non-nil when the headline should be numbered. It must return
288 a format string in which the section title will be added."

721 full file name, %b by the file base name (i.e. without directory
722 and extension parts) and %o by the base directory of the file.
724 The reason why this is a list is that it usually takes several
725 runs of `pdflatex', maybe mixed with a call to `bibtex'. Org
726 does not have a clever mechanism to detect which of these
727 commands have to be run to get to a stable result, and it also
728 does not do any error checking.
730 By default, Org uses 3 runs of `pdflatex' to do the processing.
731 If you have texi2dvi on your system and if that does not cause
732 the infamous egrep/locale bug:
734 http://lists.gnu.org/archive/html/bug-texinfo/2010-03/msg00031.html
736 then `texi2dvi' is the superior choice. Org does offer it as one
737 of the customize options.
739 Alternatively, this may be a Lisp function that does the
740 processing, so you could use this to apply the machinery of
741 AUCTeX or the Emacs LaTeX mode. This function should accept the
742 file name as its single argument."
