Pin assignments for DDR2 SDRAM tutorial

I am trying to work through the DDR2 SDRAM tutorial for Cyclone III found in the External Memory Interfaces Handbook:

http://www.altera.com/literature/lit-external-memory-interface.jsp

I have a Cyclone III development kit and this tutorial is targeted for this board. The tutorial is in Volume 6, Section I, Chapter 6 - "Using High-Performance DDR, DDR2, and DDR3 SDRAM with SOPC Builder".

Page 6-26 refers to an Altera-provided pin assignment file "C3_Dev_DDR2_Sopc_Pin_Location.tcl". I cannot locate this file anywhere. Can someone point me to this file or any documentation that will give me the proper pin assignments?

This file is also referred to in the documentation on this design example page:

http://www.altera.com/support/examples/verilog/ver-cyclone-iii-36-bit-ddr2-altmemphy.html

There is a zip file to download on this page that contains the file "CIII_DDR2.qar" but it is some kind of non-text file - I'm assuming it is an archive file. Would the pin assignment file that I'm looking for be in that? If so, how do I open it? I'm new at this.
