#* 
How would you refactor this? 

This code is workflow, which moves through a set of tasks: the config hash is a list of XML documents to convert into the database kept in YAML, before() does some setup work, download_xmls fetches hundreds of XML documents based on the config, the convert method does a lot of transformation work from xml into AR (and sometimes fetches further XML documents). Finally a report is generated and emailed to recipients to represent how the run went.

It began as a practical way to code an integration between an XML service and the app., now it's smelly. I obviously need a task based DSL, probably a state machine lib.. Any other ideas of a good DSL or library which could be adopted for it?

    def self.run
      config = YAML.load_file(@@datasets_file)
      before()
      results = download_xmls(config[:urls])
      results[:database_errors] = convert
      report = generate_report(results)
      email_report(report, config[:notify])
    end
