clang::idx -> 3.2 release

Dear Clang Community

Recently we decided to port a tool which uses clang (llvm 3.0) to the latest version (llvm 3.2) and we had some trouble with the indexing tools.
Previously there was a namespace clang::idx containing Index and Entity, which has disappeared.
I'm wondering how can I use declarations Index with new versions.
I need to find correct definition of a symbol in a set of different source files.

thanks

libclang can do this. Use the "USR" of a declaration to match it across different translation units.
