The tool is acting as a proxy betwen in-house accounting application called Abacus and specialised hardware used in retail industry. Its aim is to provide a unified way for Abacus to work with different hardware.

At the moment, there's no well-defined way to run the application, as its still under active development and not enough stable yet to be used outside of developing/testing environment. To run it inside such an environment one should go to the directory with abhard and execute the run.sh script.

Abhard is configured through etc/ahbard.yml file where different devices can be listed as well as the main port for abhard itself and some other parameters.

Unit testing is done though the standard unittest library and thus can be run e.g. like venv/bin/python3 -m unittest.
