 In order to have an easy testing of language mechanic, a simple python script has been provided in the project: [i18n_messages_properties_generator.py](src/main/resources/org/talend/sdk/component/test/connectors/i18n_messages_properties_generator.py).
 Simply execute it to generate a copy of every `messages.properties` files in multiples languages.
 The translation will add "-xx" at the end to easily test translations.

+# SimpleInput
+It's a very simple input conncetor that generates only 1 record that echoes its configuration.
