Bug#692410: license information for Math::Libm

[Florian Schlichting <fschlich@ZEDAT.FU-Berlin.DE>]

Hi,

While packaging your module Math::Libm for Debian, I noticed that it
doesn't seem to mention any licensing information, not even "same as
Perl" or anything like that. License information is needed in order for
us (and others) to be able to legally distribute the software. Could you
please give us (replying to this email is fine) the license that
Math::Libm is distributed under?

This is more than just a Debian issue. I'm not a lawyer, but it's my
understanding that both copyright and licensing information is vital for
the continued success of open source software. Copyright is what allows
you to assert a license, and a license is what gives others the rights
to use and re-distribute your software. A great article discussing some
of this is "What is Copyleft?" by Richard Stallman:
http://www.gnu.org/copyleft/

Thanks for releasing your work to the CPAN. I apologize in advance for
the noise, as I understand that the last thing most authors want to deal
with is legal administrivia like this. I do hope, however, that you
could (in your continued generosity) help us with this request. Please
also consider adding these statements to your code/package README, since
we must distribute some evidence of copyright information if it is not
in the source package itself.

Cheers,
