 It offers [three interfaces for tools](https://clang.llvm.org/docs/Tooling.html), but the only one that really works for standalone applications is [libclang](http://clang.llvm.org/doxygen/group__CINDEX.html).
 However, libclang has various limitations and does not expose the entire AST.

 If everything went succesful, it returns a `std::unique_ptr<cpp_file>` which is the top-level AST entity of the current file.
 You can then work with it.
