 - **`minidump`**: Rust bindings for the Breakpad Minidump processor. Additionally, this includes
   facilities to extract stack unwinding information (sometimes called CFI) from object files.
   This feature requires a C++11 compiler on the PATH.
-- **`proguard`**: Processing of Proguard mapping files to look up mangled Java function paths.
 - **`sourcemap`**: Processing and expansion of JavaScript source maps, as well as lookups for
   minified function names.
 - **`symcache`**: An optimized, platform-independent storage for common debugging information.
