 ** DONE
+** 0.7: Mescc supports -E, -c, -o options, include more complete set of header files,
+enough to work on compiling tinycc's tcc.c albeit a somewhat modified version.
+** 0.6: Work with unmodified, unbundled Nyacc; compile 33/55 tinycc's tests/test2 suite.
 ** 0.5: Mutual self-hosting Scheme interpreter and C compiler: mes.c and mescc,
         Support call-with-current-continuation, refactor catch/throw
 ** 0.4: Support Nyacc, Gcc-compiled Mes compiles minimal main.c using nyacc

+Subject: Mes 0.7 released
+
+I am pleased to announce the release of Mes 0.7, representing 32
+commits over 4 weeks.  Mescc now behaves more like a regular C
+compiler: supporting -E, -c, -o options and with a more complete set
+of header files [stubs]; enough to work on compiling tinycc's tcc.c
+albeit a somewhat modified version[8].
+
+* 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=v0.7 -O mes-0.7.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
