From UCSD lawyer:

I've confered with Mr. Stallman, and he still wishes to go through with the Squid assignment. He does ask that the files that are not UCSD be seperately listed, along with what jobs they do. Also, you said that these portions have their own copyright notice, so it would be helpful to have the details of that as well.

The following files/modules are copyrighted by others:
