EFL SMALL-based abstract machine (AMX) bytecode interpreter

 Embryo is a tiny library designed to interpret limited Small programs
 compiled by the included compiler, embryo_cc. It is mostly a cleaned
 up and smaller version of the original Small abstract machine. The
 compiler is mostly untouched.
 .
 Refer to the EFL documentation for an introduction to SMALL. See
 https://www.compuphase.com/pawn/pawn.htm for details on PAWN, the
 upstream successor to SMALL.

 This is part of the Enlightenment Foundation Libraries (EFL).
