AucTeX and Chapterbib

Question

Executing BibTeX via Auctex (RefTeX) in emacs (24.2.1) only creates a .bbl file for the master file in a multifile document. Yet, if one wants bibliographies for each chapter, BibTeX has to be run on each .aux file seperately. Is there a hidden option in Auctex (RefTeX) that activates this feature?

In the minimal example attached, only a .bbl file for main.tex is generated, but not for incl.tex and incl2.tex. Copying main.bbl to incl.bbl and incl2.bbl resolves the situation and both the citations and bibliographies can be found in the document.

TeX distro version: texlive 2012

RefTeX version: 4.31

main.tex

\documentclass{book}
\usepackage[round,sort&compress]{natbib}
\usepackage[sectionbib]{chapterbib}

\begin{document}

\include{incl}
\include{incl2}

\end{document}


%%% Local Variables: 
%%% mode: latex
%%% TeX-master: t
%%% End: 

incl.tex

\chapter{chap 1}

\input{inp}

\bibliographystyle{plainnat}
\bibliography{testbib} % BibTeX-File(s)


%%% Local Variables: 
%%% mode: latex
%%% TeX-master: "main"
%%% End: 

inp.tex

\section{sect1}

some text and a ref: \cite{test_01}
%%% Local Variables: 
%%% mode: latex
%%% TeX-master: "main"
%%% End:

incl2.tex

\chapter{chap 2}
\section{sect1}

some text in chap2  and same ref: \cite{test_01}

\bibliographystyle{plainnat}
\bibliography{testbib} % BibTeX-File(s)

%%% Local Variables: 
%%% mode: latex
%%% TeX-master: "main"
%%% End: 

testbib.bib

@book{test_01,
    title = {Test},
    publisher = {Test},
    author = {Adam Smith},
    year = {1982}
}

Answer 1

First, execute customize-group TeX-command. Expand TeX-command-list. Under the name field BibTeX, change the command field to bibtex %B

Next, go down to TeX-expand-list and insert a new key, %B. Add the following in the field for expander: (lambda () (substring (TeX-current-file-name-master-relative) 0 -4))

["-4" above gets rid of the extension ".tex" from the file name that will be provided to BibTeX.]

Finally, save the customization.

The above steps will ensure that when you do BibTeX on a chapter in a subdirectory, the corresponding bbl file is created in that directory. I have tried this successfully on Windows and Mac Mavericks implementations.
