"""
Tested with Pop OS (an Ubuntu clone)

# **INSTALLATION**:

## Install Python dependencies
* pip install jaydebeapi # latest version was '1.1.1' at the time of writing the gist
* pip install JPype1==0.6.3 # IMPORTANT! (latest: 0.7.2 did not work)

## Get the Persavive SQL driver

You can get it here: https://esd.actian.com/

You will have to select "Actian Zen (SQL)" as product and choose the correct version and platform.

You should end up with 3 files with the extension .jar. Those are drivers for the database written in Java.

They are meant to be used with JDBC (https://en.wikipedia.org/wiki/Java_Database_Connectivity).

## Install Java SDK

Look it up on the net.
