what is the difference between dependecies and embed in cq:clientLibraryFolder

what is the difference between dependecies and  propertieembeds in cq:ClientLibraryFolder .

• dependencies: This is a list of other client library categories on which this library folder depends. For example, given two cq:ClientLibraryFolder nodes F and G, if a file in F requires another file in G in order to function properly, then at least one of the categories of G should be among the dependencies of F.
• embed:
