-<p>Objective C provides a simpler way to declare and define accessor methods 
-using declared properties. The language provides features to declare a 
-property and to let compiler synthesize accessor methods.
-</p>
-
-<p>The debugger lets developer inspect Objective C interfaces and their 
-instance variables and class variables. However, the debugger does not know 
-anything about the properties defined in Objective C interfaces. The debugger
-consumes information generated by compiler in DWARF format. The format does 
-not support encoding of Objective C properties. This proposal describes DWARF
-extensions to encode Objective C properties, which the debugger can use to let
-developers inspect Objective C properties.

-<p>Objective C properties are always backed by an instance variable. The

-DW_AT_APPLE_property_name attribute. The instance variables with this

-variables is determined by debugger only after consulting Objective C runtime.
