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

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?
