#ifndef TRANSLATOR_EN_H

/*!
 When defining a translator class for the new language, follow
 the description in the documentation.  One of the steps says
 that you should copy the translator_en.h (this) file to your
 translator_xx.h new file.  Your new language should use the
 Translator class as the base class.  This means that you need to
 implement exactly the same (pure virtual) methods as the
 TranslatorEnglish does.  Because of this, it is a good idea to
 start with the copy of TranslatorEnglish and replace the strings
 one by one.

 It is not necessary to include "translator.h" or
 "translator_adapter.h" here.  The files are included in the
 language.cpp correctly.  Not including any of the mentioned
 files frees the maintainer from thinking about whether the
 first, the second, or both files should be included or not, and
 why.  This holds namely for localized translators because their
 base class is changed occasionally to adapter classes when the
 Translator class changes the interface, or back to the
 Translator class (by the local maintainer) when the localized
 translator is made up-to-date again.
