+<h3>Support for multiple languages</h3>
+
+Doxygen has support for multiple languages. This means 
+that the text fragments that doxygen generates can changed into languages 
+other than English (the default) at configuration time.
+<p>
+Currently, $numlang languages are supported (sorted alphabetically): 
+$languages.
+
+The table of information related to the supported languages follows.
+It is sorted by language alphabetically.  The <B>Status</B> column
+was generated from sources and shows approximately the last version
+when the translator was updated.
+<p>
+
+$information_table
+Have a look at <code>doxygen/doc/translator.txt</code> for more details.
+<p>
+
+Most people on the list have indicated that they were also busy
+doing other things, so if you want to help to speed things up please 
+let them (or me) know.
+
+If you want to add support for a language that is not yet listed 
+please see the next section.
+
+<h3>Adding a new language to doxygen</h3>
+
+This short HOWTO explains how to add support for a new language to Doxygen:
+
+Just follow these steps:
+<ol>
+<li>Tell me for which language you want to add support. If no one else
+    is already working on support for that language, you will be 
+    assigned as the maintainer for the language. 
+<li>Create a copy of translator_en.h and name it 
+    translator_<your_2_letter_counter_code>.h
+    I'll use xx in the rest of this document.
+<li>Edit language.cpp:
+    Add a 
+\verbatim
+#include<translator_xx.h>
+\endverbatim
+    in <code>setTranslator()</code> add
+\verbatim
+    else if (L_EQUAL("your_language_name"))
+    {
+      theTranslator = new TranslatorYourLanguage;
+    }
+\endverbatim
+    after the <code>if { ... }</code>
+<li>Edit libdoxygen.pro.in and add \c translator_xx.h to 
+    the \c HEADERS line in the file doxygen.pro.
+<li>Edit <code>translator_xx.h</code>:
+   <ul>
+   <li>Rename <code>TRANSLATOR_EN_H</code> to <code>TRANSLATOR_XX_H</code> twice.
+   <li>Rename TranslatorEnglish to TranslatorYourLanguage 
+   <li>In the member <code>idLanguage()</code> change "english" into the 
+     name of the your language (use lower case characters only). Depending
+     on the language you may also wish to change the member functions 
+     latexLanguageSupportCommand() and idLanguageCharset().
+   <li>Edit all the strings that are returned by the member functions that 
+     start with tr. 
+     Try to match punctuation and capitals!
+     To enter special characters (with accents) you can:
+     <ul>
+     <li>  Enter them directly if your keyboard supports that and you are 
+           using a Latin-1 font.
+           Doxygen will translate the characters to proper Latex and
+           leave the Html and man output for what it is (which is fine, if
+           idLanguageCharset() is set correctly).
+     <li>  Use html codes like \&auml; for an a with an umlaut (i.e. &auml;).
+           See the HTML specification for the codes.
+     </ul>
+   </ul>
+<li>Run configure and make again from the root of the distribution, 
+    in order to regenerated the Makefiles.
+<li>Now you can use <code>OUTPUT_LANGUAGE = your_language_name</code> 
+    in the config file to generate output in your language.
+<li>Send <code>translator_xx.h</code> to me so I can add it to doxygen.
+</ol>
+
+<h3>Maintaining a language</h3>
+
+As new versions of doxygen appear, new sentences will be
+added to the Translator interface class. Of course these need to be translated
+as well (otherwise doxygen wouldn't even compile!). 
+
+Waiting until all language maintainers have translated these new sentences
+and sent the results would not be very practical for me.
+
+Instead, a new class TranslatorAdapter_x_y_z will be added to 
+translator_adapter.h (here x,y, and z correspond to the current
+version of doxygen). And all translators that previous derived from 
+Translator will now derive from this adapter class.
+
+The Adapter class contains the new sentences with
+default translations using the English translator (which is always up to date). 
+Instead of deriving your TranslatorXX class directly from Translator it will 
+derive from the intermediate class TranslatorAdapter_x_y_z. 
+
+Thus, if a translator class inherits from a adapter class 
+maintenance is needed. By looking at the adapter class itself (and its base
+classes) you can easily see which methods need to be updated.
+
+To update a language simply make your translator class derive from
+the abstract class Translator and provide translations for the methods that
+were previously provided by the adapter class (and its base classes).
