Cool.  Does it build ok with clang?  I haven't got that set up here.  (I
might finally get a bionic build environment set up this weekend.
Fingers crossed...)

I need to write up better documentation for it, but every time I sit
down and try... there are 8 gazillion different things it _could_ be
used for.  Hard to summarize.  (Even my email in this thread describing
it was kinda long...)

The most comprehensive I've come up with is the giant presentation, 260
slides available online or a giant (90 meg) PDF:

llvm being implemented in C++ sets my teeth on edge, but since I haven't
got a better alternative...

Um, the BSDs exist?

(I'm fairly certain of this, haven't particularly used them since a
couple quick boots in the 90's where I went "yup, the gui sucks, no
drivers for any of my hardware, why are there no loopback mounts, ps is
not liking the flags I have memorized, I haven't really got spare disk
space for this..."  I tried opendarwin and solaris indiana a couple
years back, but neither of them liked qemu's emulated keyboard
controller for some reason...)
