 If you want build a platform, ACTIVE_PLATFORM must be set to your desired platform dsc file,
 go to directory which must be not a module's directory, and run "build" command.
 
+Instead of changing Target.txt, you can specify platform, module and/or architecture on command line.
+For example, if you want to build NT32 platform, you can just type 
+
+		c:\MyWork\edk2\> build -p Nt32Pkg\Nt32Pkg.dsc -a IA32

+Other helpful command line options of build tool include "-v" and "-d". "-v" option is used to turn on

+For more information on build options, please try "build -h" on command line. Note that "/?" is not working.
