License of sip

[Sandro Mani]

Hi

Updating mingw-sip I've re-verified the license to convert it to SPDX, 
and came across the SIP license which does not exist as a SPDX 
identifier. [1] states

"""

SIP is available under the following licenses.

  * SIP License. This is very similar to the Python Software Foundation
    license used for Python itself.
  * GNU General Public License v2
    <https://www.gnu.org/licenses/old-licenses/gpl-2.0.html>
  * GNU General Public License v3
    <https://www.gnu.org/licenses/gpl-3.0.html>

"""

I take this should be

License: SIP OR GPL-v2.0-only OR GPL-v3.0-only

(provided SIP existed as a SPDX identifier)?

The full SIP License text is attached.

Thanks
Sandro

I find this statement of similarity to the PSF license to be
disingenuous given that the SIP license adds a clause that
makes the license non-free IIUC:

This is an anti-competitive restriction on usage.

IIUC, since SIP looks like a non-free license, we would omit it from
SPDX expression in the RPM package, only listing the two GPL options.

With regards,
Daniel

The License: tag in this case should be `GPL-2.0-only OR GPL-3.0-only`
because we normally don't include not-allowed licenses in
OR-expressions having allowed operands (the big exception being Perl
packages which are allowed to use `GPL-1.0-or-later OR
Artistic-1.0-Perl` and `GPL-2.0-or-later OR Artistic-1.0-Perl).

I'm working on a big revision to the documentation on license tags and
am using the sip package as an example.
