// basic format you specify (B_TRANSLATOR_BITMAP, B_TRANSLATOR_TEXT etc).
// The translator ID and format constant chosen will be added to the message
// that is sent to you when the menu item is selected.
//
// The following code is a modified version of code
// written by Jon Watte from
// http://www.b500.com/bepage/TranslationKit2.html
//
// Preconditions:
//
// Parameters: intoMenu, the menu where the entries are created

//                                 if NULL, be:translator is used
//             kTranslatorTypeName, the name used for
//                                  output format id in the menuitem
//             roster, BTranslatorRoster used to find translators
//                     if NULL, the default translators are used
