CommandLineToolSet does little more than dump errors to stderr.
DummyUIManager comes from Pharo via Pavel Krivanek's minimising script.

!DummyUIManager commentStamp: 'fbs 10/31/2013 07:36' prior: 0! I'm an alternative UIManager used to run an the image without GUI. I redefine methods which require user input as these requests are irrelevant in a headless environment. !
