It acts as the underlying functional layer of whole system and if you want to reuse or integrate your wrapper you also need reuse or integrate the Runtime itself.  SGWrap Compiler (Compiler, for short), which can compile SGWrap rules into wrapper in both source code form and bytecode form. It does something like translation and the generated source code is human readable and can be modify to fulfill you special need. The bytecode is just compiled with help of Java's compiler javac.exe.  Visual SGWrap, a visual tool to generate rules. It just need you interact with it by simple selecting and clicking operation, then it can calculate out the proper rules
