I spoke with Chris Brown, who is essentially now the maintainer of qepcad. Here is his response:
"Saclib's actual status is probably a bit up in the air. What I might call the saclib "stakeholders" had agreed to GPL it, but everybody was, I guess, too busy to do anything about it. Qepcad's status is similar ... except that my contributions are necessarily public domain." In a second email, he added: "If you're interested, we can talk about this. Ultimately I can ask the saclib/qepcad folks for permission and move forward."
