+/** @file
+  Provides a service to retrieve a pointer to the start of HOB list.
+  Only available to DXE module types.
+
+  This library does not contain any functions or macros.  It simply exports a global
+  pointer to the start of HOB list as defined in the Platform Initialization Driver
+  Execution Environment Core Interface Specification.  The library constructor must
+  initialize this global pointer to the start of HOB list, so it is available at the
+  module's entry point.  Since there is overhead in looking up the pointer to the start
+  of HOB list, only those modules that actually require access to the HOB list
+  should use this library.
