A python script to convert pro6 to pptx slides

pro6-to-pptx.py

#!/usr/bin/env python3
import xml.etree.ElementTree as ET
import base64
import sys
import os
from pptx import Presentation

# Disclaimer: Also add your CCLI number to the copyright text if using output slides for a service!

# Pre-requisites: template.pptx should be an empty presentation with no slides, but with a customised master slide template

# Usage: python pro6-to-pptx.py Hosanna.pro6
# Output: Hosanna.pptx (will overwrite existing file!)
