It's a clean-room reimplementation that mimics Windows 10 program's output format. It prints all the information that is available via KerbQueryTicketCacheMessage. Also tested to work on Windows if dynamically linked + built with winegcc. For further extension of the functonality, implementing KerbQueryTicketCacheEx{,2,3}Message is required. -- v10: klist: Add a program that lists Kerberos tickets. https://gitlab.winehq.org/wine/wine/-/merge_requests/3347
