Subject: Mes 0.8 released

I am pleased to announce the release of Mes 0.8, representing 34
commits over 3 weeks.  Mescc now produces object files in the hex2
ascii output format compatible with the stage0 linker.

Special thanks to Jeremiah Orians for support with MESCC_Tools and
hex2, more goodness to follow soon!

* About

    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 Dominique Boucher's
    LALR[1], Pre-R6RS portable syntax-case[2] with R7RS ellipsis, Matt
    Wette's Nyacc[3] Guile's PEG[4] --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 was inspired by The Maxwell Equations of Software: LISP-1.5[5]
    -- John McCarthy page 13, GNU Guix's[6] source/binary packaging
    transparency and Jeremiah Orians's stage0[7] bootstrap project.

* Download

    git clone https://gitlab.com/janneke/mes

    wget https://gitlab.com/janneke/mes/repository/archive.tar.gz?ref=v0.8 -O mes-0.8.tar.gz

Mes runs from the source tree and can also be built, packaged and
installed in Guix[SD] by the usual

    guix package -f guix.scm
