Instead of
See
clive configure known-account -h
the help should contain
clive configure known-account add guest4test8
A full command ready to be copy-pasted without reading through help. Git does that in many cases and it is awesome. Even if there are too many choices to write ready command, it gives you a quick help with only relevant information, f.e. git status tells you what to do to add files to stage when there are untracked files, and what to do to revert changes when there are changed files etc.
