On Craft Client, what does the client account get? A definitive description of the client account would be useful for this. What does a client account get? For example, can they clear the cache?

I know I can login and find this out myself, but it would be helpful to have a go-to article on this for future reference.
From here:


  The Client’s Account is not an Admin account like yours, so they will not be able to access the Settings section or administrate your Admin account. They’ll be able to do everything else, though.
