  * Functions that operate on Ecore Input Method Context objects.
+
+ * Ecore Input Method Context Function defines the interface for EFL input methods. 
+ * An input method is used by EFL text input widgets like elm_entry 
+ * (based on edje_entry) to map from key events to Unicode character strings.
+ *
+ * The default input method can be set through setting the ECORE_IMF_MODULE environment variable.
+ *
+ * An input method may consume multiple key events in sequence and finally output the composed result. 
+ * This is called preediting, and an input method may provide feedback about 
+ * this process by displaying the intermediate composition states as preedit text.
+ *
+ * Immodule is plugin to connect your application and input method framework such as SCIM, ibus, and so on.@n
+ * ecore_imf_init() should be called to initialize and load immodule.@n
+ * ecore_imf_shutdown() is used for shutdowning and unloading immodule.
