- * Commandline utility for decoding Launcher3 backup protocol buffers.
- *
- * <P>When using com.android.internal.backup.LocalTransport, the file names are base64-encoded Key
- * protocol buffers with a prefix, that have been base64-encoded again by the transport:
- * <pre>
- *     echo "TDpDQUlnL0pxVTVnOD0=" | launcher_protoutil -k
- * </pre>
- *
- * <P>This tool understands these file names and will use the embedded Key to detect the type and
- * extract the payload automatically:
- * <pre>
- *     launcher_protoutil /tmp/TDpDQUlnL0pxVTVnOD0=
- * </pre>
- *
- * <P>With payload debugging enabled, base64-encoded protocol buffers will be written to the logs.
- * Copy the encoded snippet from the log, and specify the type explicitly, with the Logs flags:
- * <pre>
- *    echo "CAEYLiCJ9JKsDw==" | launcher_protoutil -L -k
- * </pre>
- * For backup payloads it is more convenient to copy the log snippet to a file:
- * <pre>
- *    launcher_protoutil -L -f favorite.log
- * </pre>
