Dear Alan, thank you very much for your quick (and very positive) answer! Concerning the upstream changes: you could for the moment just drop the "debian/" subdir. It will be replaced anyway during the packaging process, and therefore no longer maintained in your git and may be misleading for others. For any other changes, I need to look through and will come back when I have proposals.

This is a kind-of simplified BSD-3-Clause license, as f.e. this one: https://spdx.org/licenses/BSD-3-Clause The difference is mainly that the original second condition is removed/merged into the first one, and the third is then renumbered to be the second. > In which case, it should be a simple matter regardless of whatever > agreement he made with Rafael in 2003+ to convince Pavel to license > our stripped version for both nn and csa that we adopted in 2003 > under that same free software license. If PLplot can use the modern versions of the library source (or the first version from 2009 on github [1]), yes. IMO that would be the simplest way. > One minor complication is that the modern nn license text which is > otherwise completely compatible with the modern csa license text has > an additional note on the end as follows: > > Note: this software makes use of the Triangle software, which is > non-free for commercial use.

I would just remove it :-) Formal reason is that the license requires to keep only the three parts of the original license, and also I would not take the Note as part of the license at all. And pragmatically, since you don't use triangle.[ch]. > In sum, I think to deal with this licensing issue, the following 4 > steps are needed: > > 1.

I just cloned the repository and looked into his commits :-) There is one real E-mail address: <pavel.sa...@gmail.com>. This also f.e. appears in the README of the enkf-c repository. > 3.

Would you contact him? This may be even better since I am just coming from aside (and you know more about the history of the inclusion of his libraries). If the gmail address doest not work, you could even just open an issue in the nn-c or csa-c library to get in contact. I am however quite happy that the problems seems to be solvable that easy!
