Licensing

[avalentino]

The setup.py file has been recently updated to specify the license as license='GPL-3.0-or-later'.

Anyway in the classifiers section it is is specified:

License :: OSI Approved :: GNU General Public License v3 (GPLv3)

which corresponds to GPL-3.0-only, while GPL-3.0-or-later corresponds to

License :: OSI Approved :: GNU Lesser General Public License v3 or later (LGPLv3+)

Please clarify the licensing.

license='GPL-3.0-or-later' is a typo and has been removed in #36. The license is GPLv3, as indicated in the license file and classifier. Thank you for catching this.

FYI, you may find the same typo in the mintpy setup.py as well. And the license there is also GPLv3.

Dear @yunjunz, thanks a lot for the clarification.
Please note, anyway, that the attached license file is identical for GPL-3only and GPL-3+ (https://spdx.org/licenses/GPL-3.0-only.html).

For this reason I recommend, for the next release, to specify the license='GPL-3.0-only' in the setup.py in addition to classifiers, and/or to clearly state which is the applicable GPL variant in the README.md file.

Finally a question, just for my curiosity, have you considered to use LGPL instead of GPL?

Thank you for the suggestion @avalentino. I did not realize that GPLv3 and GPLv3+ have the same license file. I would be happy to switch to GPLv3+ for more flexible reusability, for both pysolid and mintpy, I will check with the pyaps owner for this as well.

I have considered the LGPL license and still prefer the ordinary GPL ones.
