I believe that there is a way one can add one or more repositories to Iceberg���s list of local repositories, so that when one opens a new image (new = just dowloaded using the Pharo launcher), the repository is already present in Iceberg���s list.�� ��St��ph showed me how to do this once, but I���ve lost the configuration file (or whatever it was) and can���t now figure out where to put it.
