The setInput() means the attachment is required to exist 
otherwise it won't invoke your deployer.
If you use addInput() then the name is only used in ordering.

If you look at the deployer interface there are actually
two different properties;
input - required attachment
inputs - only used in ordering

I guess the method should have been called setRequiredInput()
to avoid the confusion. ;-)
