>* About
>
>  GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to GuixSD[2] and
>  potentially to any other interested GNU/Linux distribution, and aims
>  to help create a full source bootstrap as part of the
>  bootstrappable builds[3] effort.
>
>  It consists of a mutual self-hosting Scheme interpreter written in
> ~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme.
>  This mes.c is being simplified[4] to be transpiled by M2-Planet[5].
>
>  The Scheme interpreter (mes.c) has a Garbage Collector, a library of
>loadable Scheme modules-- notably Dominique Boucher's LALR[6], Pre-R6RS
>[portable syntax-case[7] with R7RS ellipsis, Matt Wette's Nyacc[8]
>--and test
>  suite just barely enough to support a simple REPL and simple
>  C-compiler: MesCC.
>
>  Mes+MesCC can compile an only lightly 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-2.95.3.  This is enough to bootstrap GuixSD for
>  i686-linux and x86_64-linux.
