multibootusb/scripts/update_cfg_file.py
mbusb 85d3b5b4a4 Improvements, bug fix and new distros:-
1. Simplified 7zip listing to include directories as well
2. Correctly remove files installed outside multibootusb directory when uninstalling
3. Added Liberte
4. Added option to select zip files when choosing files
5. Added INSERT ISO
6. Added option to choose between two methods when syslinux shipped by ISO is version 3 or below
