What is there, is fine. However, the man page as is, is not very
useful since it presumes a great deal of knowledge!
I would strongly urge you to provide an EXAMPLES section utilizing
sample agent authentication.
For example, at the very least, please provide the most basic
scenario of showing exactly what one would specify in a default
installation of a CA and KRA to simply perform a "key-find" and a
"key-show" using client certification.
I would also suggest that you add your name to the list of Authors
of this man page.
