 """Decoder Generator script.
 
 Usage: generate-decoder.py <table-file> <output-cc-file> <decoder-name> \
        <options>
 
 Options include:
 
   --add_rule_patterns=bool - If bool='True', rule patterns are added (default).
         If =bool is omitted, 'True' is assumped. Legal values for bool is
         'True' and 'False'.
   --table_remove=name - Remove table 'name' from decoder. May be repeated.
   --auto-actual=name - Install automatically generated actuals into the
         decoder table with the given name. May be repeated.
   --auto-actual-sep=name - Use as separator to split up automatically
         generated actual classes.
   --auto-baseline-sep=name - Use as separator to split up automatically
         generated baseline classes.
+  --test-base=name - Test automatically genererated baseline for the
+        decoder table with the given name. May be repeated.
 
   name - Only generate tests for table 'name'. May be repeated.
 
 Note: If the file ends with named.{h,cc}, it is assumed that one should
 build the corresponding source file for named classes, so that testing
 is easier to perform. In either case, the .h file will declare a decoder
 state (with the given decoder name) to decode instructions, while the
 .cc file will define the methods for the declared decoder state.
