To create the correct layout for the files in src.zip, we create a set of directories with symlinks back to the real source. When we then run find over these symlinked directories to figure out the make dependencies, find will not follow symlinks by default.

I think this is the right thing to do because zip will follow symlinks by default as well, so it keeps the behavior of the makefile and the resulting zip file the same. I don't think we should always follow symlinks when finding files however, because most of the time, we do want the links rather than their targets in the result.

Looks good to me.

I agree with your reasoning.
