Need to Automate the Install of Management DataWarehouse thru scripts

Is there a reliable way to install the SQL Management Datawarehouse feature without using the "Configure Data Management Warehouse" Wizard from the SSMS UI?

I need an automated way to set this up, so that it works within a Continuous Intergration environment. ie: Looking for either Powershell or TSQL Scripts / Stored Procs.

I realise I can reverse engineer it to get the TSQL scripts, but am hoping that someone has documented it already.

Thanks

PS: It is it different between editions (2008R2 vs 2012) please add that insight too.
