Module Name:

  GuidList.c  

Abstract:

  Utility to create a GUID-to-name listing file that can
  be used by other utilities. Basic operation is to take the
  table of name+GUIDs that we have compiled into this utility,
  and create a text file that can be parsed by other utilities
  to do replacement of "name" with "GUID".

Notes:
  To add a new GUID to this database:
    1. Add a "#include EFI_GUID_DEFINITION(name)" statement below
    2. Modify the mGuidList[] array below to add the new GUID name

  The only issue that may come up is that, if the source GUID file
  is not in the standard GUID directory, then this utility won't
  compile because the #include fails. In this case you'd need
  to define a new macro (if it's in a standard place) or modify
  this utility's makefile to add the path to your new .h file.
