* This file defines a construct that keeps all information about a
* program:
+* - A reference point to the method to be executed on program start.
* - A list of all procedures.
* - A list of all types.
-* - A global type that can be thought of as a god-class containing all
-* global variables and procedures. This is not the base class of
+* - A global type that contais all global variables and procedures that do
+* not belong to a class. This type represents the data segment of the
+* program. It is not the base class of
* all classes in a class hierarchy (as, e.g., "object" in java).
-* - (An obstack containing global things, e.g., the above mentioned lists.)
+* - A degenerated graph that contains constant expressions.
+* - interprocedural outs state.
+* - a flag indicating validity of the interprocedural representation.
