Yes. When we build/upload new upstream releases of the library we will  
see the symbols diffs if any, i.e. dpkg-gensymbols will compare our  
symbols files (we should supply thm at some point, anyway) with the  
symbols extracted from the object files as being built from that new  
upstream release.

We just need a starting point, i.e. upload a package with symbols  
files at some point and I propose to upload the symbols files for the  
version as currently found in sid. We will have another new upstream  
version of libburn very soon, thus we will able to see such a  
comparasion then.
