REPL (repl.mes) and simple C-compiler (mescc.mes).
The simple C compiler can now compile a [[https://gitlab.com/janneke/tinycc][modified TinyCC]]. This needs
more work. A with gcc compiled tcc is [[https://lists.gnu.org/archive/html/tinycc-devel/2017-05/msg00103.html][known]] to compile GCC.
Mes is inspired by The Maxwell Equations of Software: [[http://www.softwarepreservation.org/projects/LISP/book/LISP%2525201.5%252520Programmers%252520Manual.pdf][LISP-1.5]] -- John
