License incompatability: mixes GPL 2 only plus GPL 3 codes

[mr-c]

While preparing this module for Debian, it was noticed that there is an incompatible mixture of GPL-2 and GPL-3 code:

Files: R/as.edgelist.R
Copyright: 2003-2015 Statnet Commons
License: GPL-3

Files: inst/network.api/networkapi.c
 inst/network.api/networkapi.h
 src/Rinit.c
 src/access.c
 src/access.h
 src/constructors.c
 src/constructors.h
 src/layout.c
 src/layout.h
 src/utils.c
 src/utils.h
Copyright: Carter T. Butts <buttsc@uci.edu>
           Jeffrey Horner <jeffrey.horner@gmail.com>
License: GPL-2

As per https://www.gnu.org/licenses/gpl-faq.en.html#AllCompatibility it is not permissible to mix GPL-2 and GPL-3 code.

Please consider working with the copyright holders to re-license into a compatible combination. Perhaps everything under GPL-3 or GPL-3+ would be simplest.

Thanks!

To be clear, until this incomparability is resolved, Debian can not package and release this module or any module that depends on it

Thanks!

There are two more files that still need updating:

GPL 2.0 only:
https://github.com/statnet/network/blob/master/inst/network.api/networkapi.h and .c

@mr-c, addressed in a7575e2 , by the looks of it.

@krivit Can you make a new release so that the relicensing is clear?

[mr-c]

(Many thanks, by the way!)

[krivit]

@mr-c , fairly soon, I think. @CarterButts ?

Argh, that's my mistake - I just pushed 1.16.1 and missed those two files. They are now fixed in that branch on GH, so if another bugfix release is pushed to CRAN from the 1.16.* line it will get the fixes. They are also fixed in the 1.17 line, so the next release will contain all of those changes. Sorry about that!
