The information is also available in the ...Packages file which is downloaded every time you do aptitude update . But, I believe the package contents is authoritative. That is ...Packages is generated by a scan over the actual debs, as generated and uploaded by the maintainers. I also believe that the dependency data is generated by the maintainer and hand entered at some stage in the deb creation process. > I think it is actually both.

In order to make sure that you do so, I will not give an answer. (Hey, I have no idea what might be going on.
