Listing and Setting "Local Computer Policy" with powershell

I have a handful of Windows Server 2012 servers that I need to configure.  I have found how to do it through the mmc and snap-in, but I would like to create a powershell script to be able to do it consistantly and accurately for all the servers and to quickly be able to verify the settings of all servers.  One example is:

Computer Configuration\Windows Settings\Security Settings\Advanced Audit Policy Configuration\System Audit Policies\System\Audit System Integrity

I want to be able to list the current settings to make sure that "Success and Failure" are entered and set them if they are not. 

There are almost 300 items like this that I need to set or verify.

Thanks!
