Enjoy!

* About

  GNU Mes is a Scheme interpreter and C compiler for bootstrapping the
  GNU System.  It has helped to decimate the number and size of binary
  seeds that were used in the bootstrap of GNU Guix 1.0.  Recently,
  version 0.24.2 has realized the first Full Source Bootstrap for Guix
  
<https://guix.gnu.org/en/blog/2023/the-full-source-bootstrap-building-from-source-all-the-way-down/>.
  The final goal is to help create a full source bootstrap as part of
  the bootstrappable builds effort <https://bootstrappable.org> for any
  UNIX-like operating system.

  Mes + MesCC + Mes C Library can build a bootstrappable TinyCC
  <https://gitlab.com/janneke/tinycc> that is 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.

  Mes was inspired by The Maxwell Equations of Software: LISP-1.5 --
  John McCarthy page 13, Guix's source/binary packaging transparency and
  Jeremiah Orians's Stage0 <https://github.com/oriansj/stage0>, a
  ~500-byte self-hosting hex assembler.

  [*] Use a .sig file to verify that the corresponding file (without the
  .sig suffix) is intact.  First, be sure to download both the .sig file
  and the corresponding tarball.  Then, run a command like this:

    gpg --verify mes-0.25.1.tar.gz.sig

  If that command fails because you don't have the required public key,
  or that public key has expired, try the following commands to update
  or refresh it, and then rerun the 'gpg --verify' command.

    gpg --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273

  Alternatively, Mes can be installed or updated using Guix:

    guix pull
    guix install mes

* Changes in 0.25.1 since 0.25
 ** Build
 *** The bootstrap on x86 has been fixed:
 **** The tcc-lib target is only built if lib/<kernel>/<cpu>-mes-tcc exists,
 **** If __raise is a macro, do not define it as a function.
 *** The clean targets have been fixed.
 *** The out-of-directory --srcdir build has been resurrected.

Join bug-mes@gnu.org and #bootstrappable on irc.libera.chat for
