Help wanted by app-v powershell

Hello, i want that app-v 5 packages that are not used anymore being cleaned up from my cache without clearing the whole cache.

i know this must be possible with powershell, im am just a newbie with powershell, could somebody help me?

i was thinking te following must be possible for powershell.

first check if the content share is reachable (test-connection), if not stop script.
then (get-appvclientpackage) and use the path value to test if the file is still there on the content share (test-path), it should return "True" or "False" 
when the result is "False" then remove that specific package (remove-appvclientpackage), if the result is "True" do nothing.

i think for somebody with powershell knowledge this should not be to hard to create a script to do this.

please help.
if you need more information, i will provide it.

Thanks in advance,

Johnny Bos

the result from get-appvclientpackage is for example
