Vague description of where to put core.a file

In the http://www.arduino.cc/playground/Code/Eclipse documentation in the 
section about "Copying the library from an Arduino IDE project" when discussing 
adding the arduino core.a file to an Eclipse project the following passage says 
to add it to the project, but it does not say where in the tree it should be 
added.  I added it at the top level, but I am not sure that this is the right 
place?

C:\Users\<username>\AppData\Local\Temp\buildXXXXXXXXXXXXXXXXXXXXX.tmp The X's 
in the build...tmp directory are a hash that map to the project whose temporary 
files are held in the directory. The temporary files are named after the 
project, so you can verify that you're copying the correct library. 

Copy the core.a file into your own project directory, and rename it to 
libArduinoCore.a. You can call it anything, so long as it starts with "lib" and 
ends with ".a". It might be a good idea to name the file after its target, e.g. 
libArduinoMegaCore.a, so that you can always tell what the library's target 
architecture is. 
What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?

What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?

Please provide any additional information below.
