• source/clang_ast_merge -- merge two cpp ast as one using ASTImporter
• source/clang_ast_traverse -- visit the clang ast using RecursiveASTVisitor
• source/clang_ast_visitor -- visit the clang ast using RecursiveASTVisitor
• source/clang_ast_cfg -- generate clang ast level cfg and traverse the cfg
• source/clang_ast_callgraph -- generate clang ast level call graph
• source/checkers -- clang static analyzer checker examples using plugin method
