Please clarify Net-DBus license

[intrigeri <intrigeri@debian.org>]

Hi Daniel,

I am trying to adopt the maintenance of Net-DBus in Debian under the
umbrella of the Debian Perl group, and checking its license.

Unfortunately, I am not able to find consistent information on this
topic in the 1.0.0 tarball, that would allow me to determine in with
enough certainty what the actual license of the code is:

  * README and LICENSE both contain the same set of conflicting
    information, namely
      - "under the terms of Perl itself"
      - either GPL-2+ or Artistic
    ... while Perl is GPL-1+ or Artistic

  * META.yml does not help much, given it only mentions "gpl" only,
    and points to the unversioned http://www.gnu.org/licenses/gpl.html
    URL, that currently contains... GPL version 3.

May you please clarify this somehow?

Thank you for writing and maintaining Net-DBus! :)

Regards,
