Mes -- Maxwell Equations of Software

Mes aims to create an entirely source-based bootstrapping path.  The
target is to [have GuixSD] boostrap from a minimal, easily inspectable
binary --that should be readable as source-- into something close to
R6RS Scheme.

As bootstrapping is presumably easiest and probably most fun with
Scheme, the next step for Mes is mescc: a C compiler/linker to
boostrap into GNU Gcc and GNU Guile, possibly via Tiny-CC.

It currently has an interpreter written in C (mes) with Garbage
Collector (Jam Scraper), a library of loadable Scheme modules--
notably [[https://github.com/schemeway/lalr-scm][Dominique Boucher's LALR]], [[https://www.cs.indiana.edu/chezscheme/syntax-case/old-psyntax.html][Pre-R6RS portable syntax-case]] with
R7RS ellipsis, [[http://www.nongnu.org/nyacc/][Nyacc]] and [[https://www.gnu.org/software/guile/docs/master/guile.html/PEG-Parsing.html][Guile's PEG]] --and test suite just barely
enough to support a simple REPL (repl.mes) and a proof-of-concept
C-compiler (mescc.mes) that produces an elf from the simplest of C
files.

Mes is inspired by The Maxwell Equations of Software: [[http://www.softwarepreservation.org/projects/LISP/book/LISP%25201.5%2520Programmers%2520Manual.pdf][LISP-1.5]] -- John
McCarthy page 13.
