Last updated at 6:53 am UTC on 2 July 2018
The SmartRefStream deals with

Class comment of method

	"Really write three objects: (version, class structure, object).  But only when called from the outside.  If any instance-specific classes are present, 
        prepend their source code.  byteStream will be in fileOut format.
	You can see an analysis of which objects are written out by doing: 
	(SmartRefStream statsOfSubObjects: anObject)
	(SmartRefStream tallyOfSubObjects: anObject)
	(SmartRefStream subObjects: anObject ofClass: aClass)"
