+1, please include in the update.mcm! I also like the Pharo alternative to Fuel out the error context... Lighter than full image save. Oh but we don't have Fuel yet :( Who wants to make it with a segment?

Frank Shearar uploaded a new version of CommandLine to project The Trunk: http://source.squeak.org/trunk/CommandLine-fbs.1.mcz
==================== Summary ====================
Name: CommandLine-fbs.1 Author: fbs Time: 31 October 2013, 10:32:52.821 pm UUID: dc871e85-bd16-d742-acbf-4d2b838113d1 Ancestors:
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. !
