+Brief usage for Migration Tool Fpd2Dsc.exe:
+1. Command line format:
+  Fpd2Dsc [options] input_filename
+2. Input File:
+  A syntactically valid FPD file
+3. Output Files:
+  A DSC file which syntax confirms to DSC spec.
+4. Prerequisite:
+   a. The workspace directory must be specified either by environment variable or -w option.
+     
+5. Example:
+   WORKSAPCE has already been set: $(WORKSPACE) = c:\work\EdkII. 
+ 
+   a. Fpd2Dsc -o c:\work\EdkII\Nt32Pkg\Nt32.dsc c:\work\EdkII\Nt32Pkg\Nt32.fpd
+   b. Fpd2Dsc -a c:\work\EdkII\Nt32Pkg\Nt32.fpd
+   Example a & b are equivalent to migrate Nt32 platform description file from EDKII to EDKII' snytax.
+  
+6. Known Limitations:
+   a. Tool does not handle Libraries Section since no related info in original FPD file. Developers need  to handle it manually in the output DSC file.
+   b. If MSA file which is corresponds to module guid could not be found in currect workspace, tool will dump the module guid.
