Embeddability on functions: order and chaos

Abstract
We study the quasi-order of topological embeddability on continuous functions between Polish zero dimensional spaces. Our main result is the following dichotomy: the embeddability quasi-order on continuous functions from a given compact space to another is either an analytic complete quasi-order or a well-quasi-order.
