 //! \brief A CrashReportDatabase that uses HFS+ extended attributes to store
 //!     report metadata.
 //!
 //! The database maintains three directories of reports: `"new"` to hold crash
 //! reports that are in the process of being written, `"completed"` to hold
-//! reports that have been written and are awaing upload, and `"uploaded"` to
+//! reports that have been written and are awaiting upload, and `"uploaded"` to
 //! hold reports successfully uploaded to a collection server. If the user has
 //! opted out of report collection, reports will still be written and moved
 //! to the completed directory, but they just will not be uploaded.
 //!
 //! The database stores its metadata in extended filesystem attributes. To
 //! ensure safe access, the report file is locked using `O_EXLOCK` during all
 //! extended attribute operations. The lock should be obtained using
 //! ObtainReportLock().
