[Pharo-project] Class comments are in the .sources ?

Hi folks. I was playing a bit with the ClassOrganizer stuff. I thought that class comments were in the image, but it seems they are kept in the .source. Is this correct ? They are ALWAYS kept in the .sources? I know that the class of the instancia variable "classComment" in the ClassOrganizer can be Text, ByteString or even RemoteString. I though that only those who have RemoteString were in .sources but it seems all are there. I am correct ? is this the desired behavior ? Thanks! Mariano
