"""
Sort the items of multi-item options in profiles, the following options are supported:
private-bin, private-etc, private-lib, caps.drop, caps.keep, seccomp.drop, seccomp.drop, protocol
Usage:
$ ./sort.py /path/to/profile [ /path/to/profile2 /path/to/profile3 ... ]
Keep in mind that this will overwrite your profile(s).
Examples:
$ ./sort.py MyAwesomeProfile.profile
$ ./sort.py new_profile.profile second_new_profile.profile
$ ./sort.py ~/.config/firejail/*.{profile,inc,local}
$ sudo ./sort.py /etc/firejail/*.{profile,inc,local}
Exit-Codes:
0: No Error; No Profile Fixed.
1: Error, one or more profiles were not processed correctly.
101: No Error; One or more profile were fixed.
