-  Library that provides a global pointer to the UEFI Runtime Services Tables
+  Provides a service to retrieve a pointer to the EFI Runtime Services Table.

+  This library does not contain any functions or macros.  It simply exports the
+  global variable gRT that is a pointer to the EFI Runtime Services Table as defined
+  in the UEFI Specification.  The global variable gRT must be preinitialized to NULL.
+  The library constructor must set gRT to point at the EFI Runtime Services Table so
+  it is available at the module's entry point. Since there is overhead in initializing
+  this global variable, only those modules that actually require access to the EFI
+  Runtime Services Table should use this library.
+  Only available to DXE and UEFI module types.
