Mostly a bulk conversion of debug messages, primarily with sed: sed -e 's/\(WMSG[0-9]\)\(.*\)\(\\n"\)/LOGI\2"/' This removes the '\n' from the end of the log messages, and sets them all to "info" severity. We want to prefix each line with file/line and/or a timestamp, so it doesn't make sense to have a partial line, and there's no value in embedding the '\n' in every string.
