+Subject: Mes 0.9 released
+
+I am pleased to announce the release of Mes 0.9, representing 107
+commits over 5 weeks.  Mescc now compiles to a surprisingly readable
+stage0 M1 macro assembler output format.  Mescc now compiles a
+modified TinyCC into a running [mostly segfaulting] executable.  This
+is a major milestone as tcc can compile GCC.
+
+
+* About
+
+    Mes[0] aims to create full source bootstrapping for GuixSD[1] as
+    part of the bootstrappable builds[2] project.
+
+    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.  This C prototype will be rewritten in stage0[3]
+    M1 assembly (or possibly stage2 slow-LISP, or ...).
+
+    The Scheme interpreter prototype (mes.c) has a Garbage Collector,
+    a library of loadable Scheme modules-- notably Dominique Boucher's
+    LALR[4], Pre-R6RS portable syntax-case[5] with R7RS ellipsis, Matt
+    Wette's Nyacc[6], Guile's PEG[7] --and test suite just barely
+    enough to support a simple REPL (repl.mes) and simple C-compiler
+    (mescc.mes).
+
+    The simple C compiler can compile a modified TinyCC[8].  This
+    needs more work.  A gcc-compiled tcc is known[9] to compile GCC.
