 CREATING A NEW TRANSLATION
 
 When creating a new translation you must add your language code to the
-Make_all.mak file in the lines defining LANGUAGES and MOFILES.  To create the
-initial .po file for your language you must use the command:

 INSTALLING THE TRANSLATION
 
 Install your translation with the following command:
 
-	nmake -f make_mvc.mak install

 This will create the xx\LC_MESSAGES directory in runtime\lang if it does not
 already exist.
 You can also use the following command to install all languages:
