I want to work on uemacs/PK and run it through Coverity SCAN. I can see on the repo that there are commits by different people, but I'm confused because the README only allows modifications by a particular person.
Full screen editor based on MicroEMACS 3.9e MicroEMACS was written by Dave G. Conroy and greatly modified by Daniel M. Lawrence Copyright Notices: MicroEMACS 3.9 (c) Copyright 1987 Daniel M. Lawrence. Reference Manual Copyright 1987 by Brian Straight and Daniel M. Lawrence. No copyright claimed for modifications made by Petri H. Kutvonen. Original statement of copying policy: MicroEMACS 3.9 can be copied and distributed freely for any non-commercial purposes. MicroEMACS 3.9 can only be incorporated into commercial software with the permission of the current author [Daniel M. Lawrence].
I read the history, but I can't figure out the license (it says it's shareware), and Coverity needs a valid OS license to approve the project. I can't ask the original author because he passed away in 2010, so I don't know if he made additional exceptions to his license other that the one stated in the README, or the GPL licensing of JASSPA's.
What's the license for this project? May I modify the source for my non-commercial purposes? Would it be possible to have it approved by Coverity?
