Jan Nieuwenhuizen 9f56b8b102 core: Always include reader.c, drop binary read-0-32.mo dependency. 
* module/language/c99/compiler.mes (c99-input->full-ast): Remove
  obsolete __NYACC__ and MES_FULL defines.
* src/mes.c [!MES_FULL]: Include reader-mes.h.
  (mes_builtins) [!MES_FULL]: Include reader.mes.i, reader.me.environment.i.
  [!MES_FULL]: Include reader.c.
  (main) [!MES_FULL]: By default call load_env, only call bload_env
  when --load is supplied.  WAS: Always bload read-0-32.mo.
* src/reader.c (__end_of__mes_): Remove.
  (dump): Remove option of dumping tiny test program.
* make/mescc-mes.make ($(OUT)/$(TARGET), mescc.mes-ccompile,
  mescc.mes.c-compile-E): Depend on $(OUT)/mes, scripts/mes.
* src/src.make (mes.guile): Remove module/mes/read-32-0 dependency.
  Do not build $(OUT)/mes.mes.
* module/module.make (module/mes/read-0.mo, module/mes/read-0-32.mo,
  module/mes/tiny-0-32.mo): Remove targets.
  (CLEAN): Do not add them.  Neither install $(OUT)/mes.mes.
* .gitignore: Remove exceptions for them.
* make/install.make (install): Do not install them.
* HACKING: Update info about creating module/mes/read-32-0.mo.
* scaffold/mini-mes.c: Remove.
* scaffold/tiny-mes.c: Remove.
* scaffold/cons-mes.c: Remove.
* scaffold/scaffold.make (tiny-mes.libc, tiny-mes.guile, tiny-mes.mes,
  mini-mes.libc, mini-mes.guile, mini-mes.mes): Reemove targets.

Mes -- Maxwell Equations of Software

Mes aims to create full source bootstrapping for GuixSD: an entirely
source-based bootstrap 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.

It currently consists of a mutual self-hosting [close to Guile-]
Scheme interpreter prototype in C and a Nyacc-based C compiler in
[Guile] Scheme.

The Scheme interpreter prototype (mes.c) has a Garbage Collector, 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/][Matt Wette's 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 simple C-compiler (mescc.mes) that can
produce the second initial ELF binary from binary from mes.c, in only
about 2h30'.

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, [[https://www.gnu.org/software/guix/][GNU Guix's]] source/binary packaging transparency and
[[https://github.com/oriansj/stage0][Jeremiah Orians's stage0]] bootstrap project.

Mes is free software, it is distributed under the terms of the GNU
General Public Licence version 3 or later.  See the file COPYING.
