What are the differences observed in a Jamfile if we have to use locale kit?

Two main differences:

1. Your application/binary rule (Application for instance), must have
   $(HAIKU_LOCALE_LIBS) added to his libs list
2. A DoCatalogs rule should be defined too, in order to create catalogued items from
   source. The syntax of this rule is as follow:

   DoCatalogs YourApplicationBinaryName : 
     x-vnd.YourApplicationSignature
     :
     list of catalogued source files
   ;
   

Here's AboutSystem Jamfile, doing exactly that:
