+      Class_BuildTool:
+        1) Added support of Apriori file generation from FDF file.
+        2) Added support of INF that describes binary files to put binary into FV.
+        3) Fixed single FV/FD generation error when specifying -i/-r option in GenFds.
+        
+ 
+        Code Change :
+        1) BaseTools/Bin/Win32/build.exe
+        2) BaseTools/Bin/Win32/GenFds.exe
+
+        Possible Impacts:
+        1) To generate Apriori file in FV, insert APRIORI statement just before the INF or
+        FILE statement list of the FV, For example:
+        APRIORI PEI {
+          INF  MdeModulePkg/Universal/PCD/Pei/Pcd.inf
+          FILE PEIM = B7A5041A-78BA-49e3-B73B-54C757811FB6 {
+                  SECTION PE32 = MyBinPkg\bin\ia32\PeimAfterPcd.efi
+          }
+          INF  IntelFrameworkModulePkg/Universal/StatusCode/Pei/PeiStatusCode.inf
+        }
+        2) To add binary file described by INF file into FV, only insert the INF statement
+        into the INF statements list of that FV, like this:
+        
+        INF RuleOverride=Test MdeModulePkg/Logo/Logo.inf
+        
+        Specifying how to process the binary file by defining corresponding Rule like this:
+        [Rule.Common.Base.Test]
+	       FILE FREEFORM = $(NAMED_GUID) {
+	         COMPRESS PI_STD {
+  	         GUIDED {
+                RAW BIN |.bmp   
+             }
+	         }
+	       }
