  # Instead of recursing, we'll work through a queue of components

  mapping = PurlUtil::PURL_TYPE_MAPPING[purl.type]
  return unless mapping

  @manifests[mapping] ||= Set.new
  @manifests[mapping] << Dependency.new(

  )
end

#parse!(source = nil, &block) ⇒ Object

Iterates over each manifest entry in the parse_queue, and accepts a block which will be called on each component. The block has two jobs: 1) add more sub-components to parse (if they exist), and 2) return the components purl.
