This is pretty amazing! would appreciate some more documentation on this and perhaps some benchmarks.
The system can build itself from source after clean, on my 2014 Macbook in under 0.4s. It's not exactly a standard benchmark though, but it's not slow considering that's a Lisp (like) interpreter doing all the compiling and assembling !. Footprint at the moment for everything is 158KB.
The snapshot.zip file contains 3 separate snapshots for the 3 ABIs supported currently.
