 Dump detail information
-=======================
+-----------------------
 
 You can get the list of all sections, libraries, object files, functions or
 data. You can also dump the specific symbol with the name.

 Search specific function or data
-================================
+--------------------------------
 
 You can search the target with keyword in command line. For example:

+Sort Table
+----------
+
+You can sort the messages in terminal mode. The script supplies five options and
+two orders. For example:

 Code size diff tool
 *******************
 
 Use ``code_size_diff.py`` to diff two diffrent build results with same compiler.
-Firstly, use ``code_size_analyze.py`` to prepare two different databases. For
-example:
 
 .. code-block:: bash
 
-    usage: code_size_diff.py [-h] -i [input_dbs [input_dbs ...]]
-                             [-a] [-f] [-d] [-o] [-l]
+    usage: code_size_diff.py [-h] (-S | -f | -d | -o | -l) based_db compared_db
+
+    positional arguments:
+        based_db             based databse
+        compared_db          compared databse
 
     optional arguments:
-    -h, --help            show this help message and exit
-    -i [input_dbs [input_dbs ...]], --input [input_dbs [input_dbs ...]]
-                          Input two different data base files
-    -a, --diff_all        diff summary
-    -f, --diff_function   diff function
-    -d, --diff_data       diff data
-    -o, --diff_obj        diff object file
-    -l, --diff_lib        diff library
+        -h, --help            show this help message and exit
+        -S, --diff-Summary    diff summary

+        -o, --diff-obj        diff object file
+        -l, --diff-lib        diff library
 
-Then compare two database with the diff tool, the branch1 is base.
