I can write up an outline about how to write a clang_delta pass in a 
couple of days. In the meanwhile, you can check out the excellent 
example given by Eli Bendersky:

https://github.com/eliben/llvm-clang-samples/blob/master/src_clang/rewritersample.cpp 


Both Eli's example and clang_delta follow the same principle:

(1) Inherit RecursiveASTVisitor to visit AST nodes; and

(2) rely on the Rewriter to rewrite the given source file.
