 The account_be module of the Tryton application platform.
 
+The module generates french and dutch chart of accounts / chart of taxes. The
+french / dutch XML files are generated from the same original XML file thanks
+to the localize.xsl XSLT script. The script will produce on the standard output
+the desired XML file. The XSLT script can be launched with the following
+command::
+
+   xsltproc --stringparam lang <lang> localize.xsl <xml file>
+
+where ``lang`` is either ``fr`` or ``nl``.
