# Overview:
# 
# The Makefile has been divided into phases; each phase depends on the
# previous one.  Subphases of the same phase (ie 1a, 1b) are not
# interdependent.  You can think of the build process as proceeding
# through the phases in order, but processing subphases within a given
# phase in any order.
