I'm writing a c/c++ code analyzer recently. I read some clang 
documents/tutorials. It seems there're several ways to accomplish this. 
And i'm using this tutorial <a target="_blank" href="http://eli.thegreenplace.net/2012/06/08/basic-source-to-source-transformation-with-clang,">http://eli.t<wbr>hegreenplace<wbr>.net/2012/06<wbr>/08/basic-so<wbr>urce-to-sour<wbr>ce-transform<wbr>ation-with-c<wbr>lang,</a> because it's a real sample which can be get worked. <br><br>So my question is, is there any other better ways to do this ?
