[cfe-dev] Integrating clang-based refactoring tools into IDEs - best practices?

On a side note:
For API stability, I think recent changes are pretty wild as things move
towards more and more C++11 features. Usually we find it not that much work
to keep up with the C++ APIs.
ABI stability is of course a different problem - if you want to use the
platform libs instead of just building your own version of clang's libs
into your product, I do believe exporting stuff through libclang is pretty
much the only sensible option.
