Hi Arash,

In main.tex, I have the line "\input{mypreamble}", and in mypreamble.tex,
there's a line with "\usepackage{biblatex}". I also have
several "\addbibresource{foo.bib}", "\addbibresource{bar.bib}", etc, either
in main.tex or in mypreamble.tex . I would want reftex to be aware of the
references in foo.bib and bar.bib whenever main.tex is set as TeX-master,
i.e. either while editing main.tex directly or while editing
some-section.tex, where some-section.tex sets TeX-master to main.tex.

Best,
Philipp
