This operating system sounds very interesting! How active is the development? I would imagine it's the type of thing that eventually gets "complete"

I've been gainfully employed for well over a decade working on it and it's been around in one form or another for over 40 years. We're constantly improving performance and capabilities, adding support for more hardware, supporting the specific needs of our customers etc... Just like any modern operating system, it's never really "complete". STOP is a "security from the ground up" OS, where security isn't just a first-order priority, it's the entire point, typically used in/as multilevel security solutions.

Are there any documents we can use to learn more about it? What does it look like to the user? Is it intended to be embedded?
