 DESCRIPTION:
 This library is provided by Wind River Systems Customer
 Support strictly as an educational example.
 
 This provides the functionality to display the contents of the
 sysPhysMemDesc array.  This can be useful in debugging windowing
 problems and problems adding devices using sysMmuMapAdd
 
 Architecture specific macro defines have only been added for
 PowerPc and X86.  If using this on another architecture, customer
 should check /target/h/vmLib.h for additional flags for their
 architecture
