+// This file contains the declaration of the GlobalVariable class, which
+// represents a single global variable (or constant) in the VM.
+//
+// Global variables are constant pointers that refer to hunks of space that are
+// allocated by either the VM, or by the linker in a static compiler.  A global
+// variable may have an intial value, which is copied into the executables .data
+// area.  Global Constants are required to have initializers.
