 Usage:

  -To do all the process in a single step:
    python Manager.py do <taskfile> <projectname> [ <path> ]
	  NOTE: it will not perform an automatic clean
   
  -To do every step individually (in this order):
    python Manager.py download <taskfile> <projectname> <path>
    python Manager.py runannotator <taskfile> <projectname> <path>
    python Manager.py upload <taskfile> <projectname> <path>

  -To clean all the task-related files:
    python Manager.py clean <taskfile> <projectname> <path>

  -To get a list of all the modified descriptor files:
    python Manager.py listmodified <taskfile> <projectname> <path>
