Where SharePoint 2013 Client Object Model Redistributable Download?

Hi,

I am looking for Where SharePoint 2013 Client Object Model Redistributable Download.

I know the SP fundation 2010 is available here: http://www.microsoft.com/en-us/download/details.aspx?id=21786

However, I am looking for SP13 Server (not foundation)  Redistributable .

Thank you,
