Hi!

I give you Mes ;-)

Figure this first self-hosting version deserves a place in Guix.  Mes
should not have any dependencies of course; the fact it lists Guile,
Gcc, i686-binutils, i686-gcc and Perl is because we're still
bootstrapping.

When Mes is able to compile Gcc and close the full source bootstrapping
loop, all dependencies will be gone.

Greetings,
janneke
