I was going to prepare a patchset to remove the list of packages from
the manual, when I stumbled on *one* reason parts of it is interesting
to have in the manual: the list of virtual packages, their symboles and
their providers.

I think this is worth having in the manual, if at least for packagers of
new packages that would need or provide such a virtual package.

However, I think the normal and deperacted packages should be removed,
and our script made much simpler (if at all possible).

So, what's the idea:
  - remove all packages (easy)
  - keep as-is  (even easier)
  - only keep virtual packages (not easy at all)

Insights? ;-)

Yann E. MORIN.
