   //! \brief Returns key-value string annotations recorded in the module.
   //!
   //! This method retrieves annotations recorded in a module. These annotations
   //! are intended for diagnostic use, including crash analysis. “Simple
   //! annotations” are structured as a sequence of key-value pairs, where all
   //! keys and values are strings. These are referred to in Chrome as “crash
   //! keys.”
   //!
   //! For Mac OS X snapshots, these annotations are found by interpreting the
   //! `__DATA, __crashpad_info` section as `CrashpadInfo`. Clients can use the
-  //! Crashpad client interface to store annotations in this structure.
+  //! Crashpad client interface to store annotations in this structure. Most

   //! The annotations returned by this method do not duplicate those returned by
-  //! AnnotationsVector().
