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

 154   "Alist of LaTeX classes and associated header and structure.
 155 If #+LaTeX_CLASS is set in the buffer, use its value and the
 156 associated information.  Here is the structure of each cell:
 157
 158   \(class-name
 159     header-string
 160     (numbered-section . unnumbered-section\)
 161     ...\)
 162
 163 The header string
 164 -----------------
 165
 166 The HEADER-STRING is the header that will be inserted into the LaTeX file.
 167 It should contain the \\documentclass macro, package call via \\usepackage
 168 and anything else you would always like to have in the header.  Note that
 169 the header will be augmented with additional usepackage statements
 170 according to the variable `org-export-latex-packages-alist', and also with
 171 lines specified via \"#+LaTeX_HEADER:\".
 172 If the header definition contains \"\\usepackage[AUTO]{inputenc}\", AUTO
 173 will automatically be replaced with a coding system derived from
 174 `buffer-file-coding-system'.  See also the variable
 175 `org-export-latex-inputenc-alist' for a way to influence this mechanism.
 176
 177
 178 The sectioning structure
 179 ------------------------
 180
 181 The sectioning structure of the class is given by the elements following
 182 the header string.  For ech sectioning level, a number of strings is
 183 specified.  A %s formatter is mandatory in each section string and will
 184 be replaced by the title of the section.
 185
 186 Instead of a cons cell (numbered . unnumbered), you can also provide a list
 187 of 2 or 4 elements,
 188
 189   (numbered-open numbered-close)
 190
 191 or
 192
 193   (numbered-open numbered-close unnumbered-open unnumbered-close)
 194
 195 providing opening and closing strings for an environment that should
 196 represent the document section.  The opening clause should have a %s
 197 to represent the section title.
 198
 199 Instead of a list of sectioning commands, you can also specify a
 200 function name.  That function will be called with two parameters,
 201 the (reduced) level of the headline, and the headline text.  The functions
 202 returns a cons cell with the (possibly modified) headline text, and the
 203 sectioning list in the cdr."
