Description
It must be very common to have a single bibtex database symlink'd to every tex document directory. Given that this is a common strategy, pybliographer ought to be smarter about preserving symlinks. Is there a best practice here? How about checking whether the save path is a symlink and acting appropriately? There is a race condition here, but it 99% of the cases it should do the right thing.
