# NOTE: This class is not intended for internal use by the chef-client code. Classes in
# chef-client should still have objects like the node and run_context injected into them
# via their initializers. This class is still global state and will complicate writing
# unit tests for internal Chef objects. It is intended to be used only by recipe code.
# NOTE: When adding require lines here you are creating tight coupling on a global that may be
# included in many different situations and ultimately that ends in tears with circular requires.
# Note the way that the run_context, provider_priority_map and resource_priority_map are "dependency
# injected" into this class by other objects and do not reference the class symbols in those files
# directly and we do not need to require those files here.
