Create Group Policy - Drive Mappings via Script?

Hi,

I am trying to create a lot of Group Policy Drive Mapps

http://technet.microsoft.com/en-us/library/cc770902.aspx

I have been looking for some API's / powershell to do this?

Is there any way of automating this so I don't need to do
edit the GPO Object manually for every mapping?

Thanks,

Ward
