This file shows how create simple "remote kernel" process that can be accessed through ZMQ from, say, Mathematica or RStudio notebooks.
Since the code is small it can be included inside Mathematica or R packages. See the Mathematica package RakuMode.
The code below is an adaptation of one of the introductory codes from the ZMQ guide. See "ĆMQ - The Guide", "Chapter 1, Basics".
