Bibliography and Cite

Hello,

I wish to have a bibliography handled as it is in TeX: a bib file somewhere, in the text I call \cite{ref} and a bibliography appears.

\cite{ref} is transfromed into a well formed expression in the text, that it only depends on a key attached to the full reference in the bib file, and the bibliography lets appear only what I have cited.

Any idea of a module doing this?

Thanks,

-Fred
