I uploaded the docs to share the details with friends and it can be downloaded [1], but at this time it's not productized in any way. The public-facing docs are incomplete (there are more that I have private), it doesn't commit to backwards compatibility, it needs to be faster to compile scripts and I'd need to improve the IntelliJ plugin etc.
Every so often I think about open sourcing it so I can use it in more contexts than just private use, but running open source projects can be a lot of work, it depends on some libraries that would have to go first, and I have customers to attend to so I just end up not getting around to it.
