 # EdkCompatibilityPkg is based on the EDK 1.01 release, found at http://edk.tianocore.org. This package only 
 # contains the header files and libraries found in the original EDK. EdkCompatibilityPkg code is ANSI C compliant, so the modules can be built with GCC tool-chains. 
 # This package also incorporates bug fixes released in EDK 1.04.
