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