copyright files and GPL links

[Gerfried Fuchs <rhonda@deb.at>]

        Hi!

 The policy says that packages should refer to the files in the
common-licences directory instead of quoting the licence text itself.
This is done, but I think there is one common mistake on a lot of
packages (not only games related ones):  They point to the GPL symlink
instead of GPL-2.

 While it might be convenient to do so, I think it is wrong.  When the
license states that it is "GPLv2 (or later)" it should IMHO point to the
GPL-2 file.  There are discussions going on what to do with the GPL
symlink, and some suggest that it should point to the GPLv3.

 I don't think that a forced-upgrade is something that is really wanted
(and I doubt that the symlink change will get done).  But that was also
the reason with the sources.list file where it was switched from the
"stable" symbolic name directly to the release codenames.

 So long,
Rhonda
