1. bin and kbin folders are dynamically generated 2. Context comes before depend, so the bin and kbin folders are created in the context construction phase. When the depend process comes, each library is downloaded, and a relative bin/xxx and kbin/xxx directory is created for each library to place files. This is to prevent duplicate file names.
