This is a small thing, but might be useful. Currently Breeze prints the Asciiart when started. You should be able to persistently disable the asciiart.

This is done with storing the rigth "flag" file in the ".build" directory. If the file is there, the ASCIIART should not be printed. If not, it shoudl be printed.
