[cfe-dev] what's the best way to writing a code analyzer with clang?

[kevinlynx]

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 http://eli.thegreenplace.net/2012/06/08/basic-source-to-source-transformation-with-clang, because it's a real sample which can be get worked. 

So my question is, is there any other better ways to do this ?
