+Abstract:
+
+  PEI Debug macros. The work needs to be done in library. The Debug
+  macros them selves are standard for all files, including the core.
+  
+  There needs to be code linked in that produces the following macros:
+  
+  PeiDebugAssert(file, linenumber, assertion string) - worker function for 
+      ASSERT. filename and line number of where this ASSERT() is located
+      is passed in along with the stringized version of the assertion.
+  
+  PeiDebugPrint - Worker function for debug print
+
+  _DEBUG_SET_MEM(address, length, value) - Set memory at address to value
+    for legnth bytes. This macro is used to initialzed uninitialized memory
+    or memory that is free'ed, so it will not be used by mistake.
