/** @file\r
- Public include file for the Debug Library\r
+ Provides services to print debug and assert messages to a debug output device.\r
+ \r
+ The Debug library supports debug print and asserts based on a combination of macros and code.\r
+ The debug library can be turned on and off so that the debug code does not increase the size of an image.\r
+\r
+ Note that a MDEPKG_NDEBUG macro is introduced to switch on/off debug and assert related macros.\r
+ 1. If MDEPKG_NDEBUG is defined, then debug and assert related macros are NULL.\r
+ 2. If MDEPKG_NDEBUG is not defined, then PcdDebugProperyMask is used to turn on/off these helper macros.\r
