Hello dear FTP masters,

I was sort of expecting NEW processing due to the new component tarball,
but I see that didn't happen. The licensing of this code is somewhat
hairy, and I'd very much appreciate a review. Our thinking is that this
fixes a longstanding DFSG 'missing source' issue (#762638) so in a sense
it cannot be a regression from what Debian has now. We therefore made
the decision to upload first and request a review afterwards.

As documented in debian/copyright of 5.26.1-1, line 1982 onwards (diff
attached as copyright.diff), parts of the source are under a modified
Artistic license (diff to the common-licenses version attached for your
convenience as artistic.diff). In my understanding, this tries to be more
permissive than the original one and allows relicensing under certain
conditions that I hope are met.

FWIW, code under this modified Artistic license is already present in
a few packages in the archive, most notably 'dist' itself, though it
looks like the fact has gone unnoticed on the Debian side until now.

Many thanks for your important work on Debian, and please let me know
if you need further information on this.

The relevant debian/copyright changes are at
    https://anonscm.debian.org/cgit/perl/perl.git/commit/?id=7b26d5835a0c243f50ab2b4758ddf8a3ab6b69d1
and attached as copyright.diff, which includes the modified
Artistic license.

Diff between /usr/share/common-licenses/Artistic and
    https://github.com/rmanfredi/dist/blob/master/Artistic
is attached as artistic.diff.
