Comment 1 for bug 1095173

I thought about the use of libapt-pkg before implementing the package information feature this way but I found no good idea how to do so because of the bad API documentation in libapt-pkg-doc.
Additionally, I plan to change the display of the fetched information so that they are better structured.
Any, I'll think again about libapt-pkg as well as I do with libgraphviz.
