Live-bootstrap

I guess that this first time that I heard something related to live-bootstrap was on June 24, 2019, because on that day I posted a link to Stage 0: A set of minimal dependency bootstrap binaries. Since that time, I have been working on writing software to understand and document live-bootstrap. This has already resulted in generating some pages with detailed information:

A page based on a program analyzing the input files.
A page based on parsing the output of strace
