  29 ;; This library implements a LaTeX exporter for org-mode.
  30 ;;
  31 ;; It is part of Org and will be autoloaded
  32 ;;
  33 ;; The interactive functions are similar to those of the HTML exporter:

 117   "Alist of LaTeX classes and associated header and structure.
 118 If #+LaTeX_CLASS is set in the buffer, use its value and the
 119 associated information.  Here is the structure of each cell:
 120
 121   \(class-name
 122     header-string
 123     (numbered-section . unnumbered-section\)
 124     ...\)
 125
 126 The header string
 127 -----------------
 128
 129 The HEADER-STRING is the header that will be inserted into the LaTeX file.
 130 It should contain the \\documentclass macro, and anything else that is needed
 131 for this setup.  To this header, the following commands will be added:
 132
 133 - Calls to \\usepackage for all packages mentioned in the variables
 134   `org-export-latex-default-packages-alist' and
 135   `org-export-latex-packages-alist'.  Thus, your header definitions should
 136   avoid to also request these packages.
 137
 138 - Lines specified via \"#+LaTeX_HEADER:\"
 139
 140 If you need more control about the sequence in which the header is built
 141 up, or if you want to exclude one of these building blocks for a particular
 142 class, you can use the following macro-like placeholders.
 143
 144  [DEFAULT-PACKAGES]      \\usepackage statements for default packages
 145  [NO-DEFAULT-PACKAGES]   do not include any of the default packages
 146  [PACKAGES]              \\usepackage statements for packages
 147  [NO-PACKAGES]           do not include the packages
 148  [EXTRA]                 the stuff from #+LaTeX_HEADER
 149  [NO-EXTRA]              do not include #+LaTeX_HEADER stuff
 150  [BEAMER-HEADER-EXTRA]   the beamer extra headers
 151
 152 So a header like
 153
 154   \\documentclass{article}
 155   [NO-DEFAULT-PACKAGES]
 156   [EXTRA]
 157   \\providecommand{\\alert}[1]{\\textbf{#1}}
 158   [PACKAGES]
 159
 160 will omit the default packages, and will include the #+LaTeX_HEADER lines,
 161 then have a call to \\providecommand, and then place \\usepackage commands
 162 based on the content of `org-export-latex-packages-alist'.
 163
 164 If your header or `org-export-latex-default-packages-alist' inserts
 165 \"\\usepackage[AUTO]{inputenc}\", AUTO will automatically be replaced with
 166 a coding system derived from `buffer-file-coding-system'.  See also the
 167 variable `org-export-latex-inputenc-alist' for a way to influence this
 168 mechanism.
 169
 170 The sectioning structure
 171 ------------------------
 172
 173 The sectioning structure of the class is given by the elements following
 174 the header string.  For each sectioning level, a number of strings is
 175 specified.  A %s formatter is mandatory in each section string and will
 176 be replaced by the title of the section.
 177
 178 Instead of a cons cell (numbered . unnumbered), you can also provide a list
 179 of 2 or 4 elements,
 180
 181   (numbered-open numbered-close)
 182
 183 or
 184
 185   (numbered-open numbered-close unnumbered-open unnumbered-close)
 186
 187 providing opening and closing strings for a LaTeX environment that should
 188 represent the document section.  The opening clause should have a %s
 189 to represent the section title.
 190
 191 Instead of a list of sectioning commands, you can also specify a
 192 function name.  That function will be called with two parameters,
 193 the (reduced) level of the headline, and the headline text.  The function
 194 must return a cons cell with the (possibly modified) headline text, and the
 195 sectioning list in the cdr."

 685
 686 If you set `org-create-formula-image-program'

 700 `pdflatex', maybe mixed with a call to `bibtex'.  Org does not have a clever
 701 mechanism to detect which of these commands have to be run to get to a stable
 702 result, and it also does not do any error checking.
 703
 704 By default, Org uses 3 runs of `pdflatex' to do the processing.  If you
 705 have texi2dvi on your system and if that does not cause the infamous
 706 egrep/locale bug:
 707
 708      http://lists.gnu.org/archive/html/bug-texinfo/2010-03/msg00031.html
 709
 710 then `texi2dvi' is the superior choice.  Org does offer it as one
 711 of the customize options.
 712
 713 Alternatively, this may be a Lisp function that does the processing, so you
 714 could use this to apply the machinery of AUCTeX or the Emacs LaTeX mode.
 715 This function should accept the file name as its single argument."
