"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 extension) 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, mixed with a call to bibtex. Org does now have a clever
mechanism
+to detect how many times the document has to be compiled to get
to a stable
+result for the cross-references. Moreover, the number of
compilations
after
+bibtex is limited to 3 by default (see `org-latex-pdf-max-runs'
for more).
+Though, it does not do any error checking.
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."

Enhancements:
- variable to limit the number of PDFLaTeX runs (3, by default)
Though, the way it is evaluated, you need to set it before calling
org-latex
(before defining org-latex-to-pdf-process). Not a problem, IMHO.
Maybe
there
are better ways, though?
- real standard sequence to compile the doc:
+ one call to PDFLaTeX
+ one call to BibTeX
+ as many calls as needed to PDFLaTeX (max 3)
