module Vienna
  
  # When we call each task, we instance_eval it into a scope so we can set
  # various constants on that scope without effecing anything else....
  # TaskScope is that context
  class TaskScope
    
    # access the task variables: hash of names => values
    attr_reader :task_variables
    
    # to maintain the righe opalfile for the current scope. The Task's actual
    # opalfile might have some taks soverridden, so we cannot rely on using that
    # opalfile to get prerequirement tasks. This task scope keeps us in the 
    # correct scope.
