# Biber not run automatically with -shell-escape?

I vaguely recall reading somewhere that biber can be run automatically by the biblatex package when -shell-escape is allowed.

Do I remember it wrong? As much as I try, biblatex only tells me to run biber by hand.

EDIT using TexLive2010 (updated about one month ago).

EDIT2 (MWE): I run this code with xelatex, biber, xelatex; I expected biber to be run automatically by biblatex using \write18.

\documentclass{article}
\usepackage[backend=biber]{biblatex}
\usepackage{filecontents}

\begin{filecontents}{aa.bib}
@book{FooBar2000, author={Foo Bar}, title={Some Title}, publisher={Springer}, year={2000}};
\end{filecontents}

\begin{document}
According to \cite{FooBar2000} \dots
\printbibliography
\end{document}

Can you provide with a MWE? And tell us exactly what is wrong? What distribution are you using, what are the commands that you are invoking to compile etc... –  Martigan Dec 15 '11 at 14:46
@Martigan: Really? This is one of those rare occasions where an MWE makes no sense. –  qubyte Dec 15 '11 at 14:49
@Mark: A minimal example makes sense. I could copy and paste and so try in a easy way if the automatic call works for me. –  Ulrike Fischer Dec 15 '11 at 14:51
@UlrikeFischer: I stand by my comment. I can't see how an MWE would expedite anything in this case, since the answer will either be from someone who is reading or has read the manual, is a google wizard, or who already knows how to do it. MWEs are usually a good thing to put into a question, but not at the cost of being concise. –  qubyte Dec 15 '11 at 15:12
@Martigan: I also think MWE makes it only less clear. The question is about whether is biblatex supposed to run biber automatically by design in the first place; if so, only then a MWE makes sense. –  eudoxos Dec 15 '11 at 16:29

As far as I know there is no provision for running biber automatically, nor has there ever been. Neither biblatex nor biber mention such an option in their documentation, so I think you must have been mistaken.
If you use latexmk it will automatically run biber as needed.
It might do it, but not at the time of \printbibliography, as the .aux file must be closed; so this wouldn't spare a LaTeX run. –  egreg Dec 15 '11 at 18:32
