[Pharo-dev] Why is there a __MACOSX directory in the zeroconf linux download?

Hi - I just noticed when trying out zeroconf on an EC2 instance that the resulting download for the 64 bit vm has a __MACOSX directory in it in the pharo-vm/lib/5.x directory? Isn’t this built with a CI server - so why is that file in there? Or are these vm’s hand built? Tim
