Documentation:
Commands to process a LaTeX file to a PDF file.
This is a list of strings, each of them will be given to the
shell as a command. %f in the command will be replaced by the
full file name, %b by the file base name (i.e. without directory
and extension parts) and %o by the base directory of the file.

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.
If you have texi2dvi on your system and if that does not cause
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.

You can customize this variable.
