Hello everyone,

According to the document, chef client will first load all the libraries from every cookbook at its compile time.  
But in what order the libraries are loaded? Is it the order of cookbooks in the run list?

Thank you.

The logic is all there already, so it shouldn't be much work if someone wants to take this on.
