So their readme is "very" confusing to someone that does not know python
nothing on the readme says 'python3 -m livefs_edit'.

rm ../test.iso 2> /dev/null ; python3 -m livefs_edit
../ubuntu-22.04.3-live-server-amd64.iso ../test.iso --cp ../grub.cfg
/boot/grub/grub.cfg

set up loop device /dev/loop16 backing
../ubuntu-22.04.3-live-server-amd64.iso
found live iso9660 filesystem on /dev/loop16p1
running cp with arguments {'source': '../grub.cfg', 'dest':
'/boot/grub/grub.cfg'}
Traceback (most recent call last):

    with open(src, 'rb') as fsrc:

I dont know what to do with that ?
Thanks
