Not too helpful.

   -f specifies the lastlogin FILE to use, not fields
   As mentioned, I'm trying to use --libxo text, not xml

Looking to get lastlogin to print a single line:
   wayne last login: Fri Apr 12 15:06:16 2024 from 192.168.63.146


I'm guessing I need the printf equivalent for libxo but it appears
not to be documented anywhere.

So something like:
   lastlogin --libxo '("%s last login in at %s from %s ", user, login-time, from)' wayne
