Yes, I've found some of it. Unfortunately much of the useful stuff
data is buried in PDFs, so it costs time and effort to convert the PDFs
into something useful. (I've never understood the apparent attitude
that surface glitz is so important it's worth impairing content
accessibility and usability for.)

Given its size, that's what I'd expect. 264K of RAM doesn't hold much.

Easy? I disagree. Nothing involving cmake is easy. Not for me.
Also, based on what little I've found so far, it requires gcc so recent
it's not usable for my purposes. And python, just in case two
showstoppers weren't enough.

8.3.0? Much too recent for me. (Besides, pkgsrc isn't interested in
supporting me.)
