Install RDS CAL's on Server 2012 using Powershell

Hi all,

I am trying to figure out how to activate an RDS Licensing role and install CAL's on a Windows Server 2012 Standard box. I have created an RDS Deployment, and installed all the necessary roles, I have configured the Licensing Mode and the license server list at the deployment level, however, I need to be able to activate and install CAL's (using my SPLA info) via Powershell (or command line). I know there was a fairly simple way to do this in 2008 R2, but I can't figure it out for 2012. Any help is appreciated.
