 """Generate a C++ header from input_methods.txt.
 
 This program generates a C++ header file containing the information on
 available input methods.  It parses input_methods.txt, and then generates a
 static array definition from the information extracted. The input and output
 file names are specified on the command line.
+The header input_methods.h is used in input_method_whitelist.cc which is for
+testing purpose.
 
 Run it like:
   gen_input_methods.py input_methods.txt input_methods.h
 
 It will produce output that looks like:
 
 // This file is automatically generated by gen_input_methods.py
 #ifndef CHROMEOS_IME_INPUT_METHODS_H_
 #define CHROMEOS_IME_INPUT_METHODS_H_
