Convert old PyRadio themes to new format

README.md

This is a simple script to convert an old PyRadio theme to the new format!

Usage:

python pyradio_convert_theme.py [FILE | THEME NAME]

Note: Please make sure you are using the same pallette as the one used when the original theme was created

pyradio_convert_theme.py
