+"""Generate a C++ header from ibus_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.
+
+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 CHROME_BROWSER_CHROMEOS_INPUT_METHOD_INPUT_METHODS_H_
+#define CHROME_BROWSER_CHROMEOS_INPUT_METHOD_INPUT_METHODS_H_
