I have only downloaded a bibtex utility to export the bib entries that cited in the TeX documents. It contains .dtx and .ins, but the instructions is not really clear enough to install it into my system (Ubuntu 12.04). I have to locate /usr/share and find that there are two folders inside. They are /usr/share/texmf/ and /usr/share/texmf-texlive/. I have ever installed additional packages in TeX, so I know the way to update TeX sysem. But in order to add a new utility, I don't know which one of them is better. Currently, I don't see the folder utils in both.
Could you give me an advice to install the util bibexport please? Any suggestion always appreciates.
bibexportbundle should be available with one of the provided (Debian) packages for TeX Live 2012 (texlive-bibtex-extra) – egreg Jan 20 at 11:16~/texmf(test withkpsewhich --var-value TEXMFHOME). Just make sure that the subfolders oftexmfmimic the structure of your 'system' tree. – jon Jan 21 at 3:27
