  Used to run tests and run the devel site.

  Uses Make to ensure the dev database is running. Consult db.makefile for more
  DB control options.

  CMD can be:

      devel    -- Assumed if no CMD is given. Launches development site.
      test     -- Runs Stack tests. Does not launch site.

      cleandb  -- Blow away the database.

  'test' accepts any additional options native to 'stack test'
