=============== Diff against System-bf.997 ===============

Item was changed:
  ----- Method: Project>>dispatchTo:addPrefixAndSend:withArguments: (in category 'dispatching') -----
  dispatchTo: requestor addPrefixAndSend: baseSelector withArguments: arguments
  	"Sender wants to perform a method with dependencies on the type of project.
  	Dispatch to an appropriate method for the current project.
  
- 	If additional base selectors are added for dispatching, the list of base selectors
- 	in Project class>>baseSelectors should be updated.
- 	
  	This method is a workaround for lack of proper ToolBuilder support in the sender,
  	and should be eliminated when possible (dtl Feb 2010)"
