newsusers & ckpasswd

[Andrija Gencel]

two simple questions:

1.
what is the format of the newsusers file mentioned in the readers.conf
manual?
auth all {
            auth: "ckpasswd -d /usr/local/news/db/newsusers"
            auth: "ckpasswd -s"
        }
2.
i need some help for the "chpasswd" program, does it have an option to
read a simple 
password file with non encripted passwords, and what is the format of
that file? 


Thanks. A*
