powershell to report both share and directory level permissions

I am after a power shell command that will report for all shares on a server, both the share and directory level permissions, written to *.CSV. Is this possible? I used to use a tool called MBSA which would include these in an easy to view format, but its recently been retired, so a power shell replacement would be most useful. My understanding is both need to be considered with determining access, as it works of a premise of the most restrictive permission takes effect.
