#+SUBTITLE: Maxwell Equations of Software
[[https://www.gnu.org/software/mes][GNU Mes]] is a Scheme interpreter and C compiler for bootstrapping the GNU
System. Since version 0.22 it has again helped to halve the size of
opaque, uninspectable binary seeds that are currently being used in the

The Scheme interpreter is written in ~5,000 LOC of simple C, and the C
compiler written in Scheme and these are mutual self-hosting. Mes can

Mes + MesCC + Mes C Library can build a [[https://gitlab.com/janneke/tinycc][bootstrappable TinyCC]] that is
self-hosting. Using this tcc and the Mes C library we now have a
Reduced Binary Seed bootstrap for the gnutools triplet: glibc-2.2.5,
self-hosting. Using this bootstrappable-tcc and the Mes C library we
can build an ancient version of the GNU tools triplet: glibc-2.2.5,
binutils-2.20.1, gcc-2.95.3. This is enough to bootstrap Guix for
i686-linux, x86_64-linux, armhf-linux and aarch64-linux.
