How to include bib file in Tex

I need to submit my TeX file to journal but they request

Do not include a separate .bib file or .bbl file with your submission

and

If I upload a TeX file but not the .pdf file including the .bib results. How should I merge my .bib file with my TeX file ?

Welcome to TeX.sx!. You might start by checking the folder of your compiled TeX file to find a file with the .bbl extension. That is your processed .bib file. Then you can include the contents of that file in your bibliography and citations will work. I would really consider issuing a complaint to the journal as this is a ridiculous requirement. –  percusse Oct 22 '12 at 13:24
See Herbert's answer to essentially the same question. –  Andrew Swann Oct 22 '12 at 13:26
@percusse They just want a single document. Just substituting the \bibliographystyle-\bibliography pair with the contents of the .bbl file is what's needed. –  egreg Oct 22 '12 at 13:28
@AndrewSwann That is good if biblatex is used. For "old style" bibliography with BibTeX that's meaningless. –  egreg Oct 22 '12 at 13:29
@AndrewSwann Oh, I see the point. Now it's kerr's turn to be more precise about this. –  egreg Oct 22 '12 at 13:33
