+Subject: Mes 0.16 released
+
+I am pleased to announce the release of Mes 0.16, representing 27
+commits over 2 weeks.
+
+A most annoying ELF header bug was fixed that suddenly had all Mes
+binaries segfault before entering `_start' on Linux 4.17 and later.
+
+We now have binutils-2.20.1 and gcc-4.1.0, both compiled with
+gcc-2.95.3 and glibc-2.2.5.
+
+This reduced-binary-seed bootstrap still depends on these bootstrap
+binaries: BOOTSTRAP-GUILE, flex, bash, bzip2, coreutils, diffutils,
+gawk, grep, gzip, make, sed, tar, on the small binary seeds:
+tinycc-seed, mescc-seed and on the mes.M1 ASCII seed.
+
+Next targets:
+
+ - build a Gcc 4.7 and Glibc 2.23
+ - upstream the x86 Mes bootstrap to GuixSD
+ - reduce the 1MB ASCII M1 seed to ~5000 LOC/~100KB of M2 source
+ - revive Gash: a posix shell for Guile to reduce the bootstrap binary
+ dependencies
+ - and/or otherwise reduce the bootstrap binary dependencies
+
+Packages are available from Guix's wip-bootstrap branch.
+
+* About
+
+Mes[0] aims to help create full source bootstrapping for GuixSD[1] as
+part of the bootstrappable builds[2] effort.
+
+It currently consists of a mutual self-hosting Scheme interpreter
+prototype written in C and a Nyacc-based C compiler written in Scheme.
+This C prototype is being simplified[3] to be transpiled by M2-Planet[4].
+
+The Scheme interpreter prototype (mes.c) has a Garbage Collector, a
+library of loadable Scheme modules-- notably Dominique Boucher's LALR[5],
+Pre-R6RS portable syntax-case[6] with R7RS ellipsis, Matt Wette's Nyacc[7],
+Guile's PEG[8] --and test suite just barely enough to support a simple
+REPL and simple C-compiler: MesCC.
+
+Mes+MesCC can compile an only lighty patched TinyCC[9] 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,
+binutils-2.20.1, gcc-4.1.0.
+
+Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10] --
+John McCarthy page 13, GNU Guix's source/binary packaging transparency
+and Jeremiah Orians's stage0[11] ~500 byte self-hosting hex assembler.
+
+* Download
+
+ git clone https://gitlab.com/janneke/mes
+
+ wget https://gitlab.com/janneke/mes/-/archive/v0.16/mes-0.16.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
