Localization resources

[Ann & Jason Edmeades]

Hiya,

If adding files for translation to a new directory (xcopy), can anyone
confirm of deny whether the following is all I need to do:

1. Add rsrc.rc containing (* - see below)
    #include <windows.h>
    #include "resources.h"
    LANGUAGE LANG_NEUTRAL, SUBLANG_NEUTRAL
    #include "En.rc"

2. Add En.rc containing 
    LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US
    STRINGTABLE DISCARDABLE LANGUAGE LANG_ENGLISH, SUBLANG_DEFAULT
    {
    id1, "string"
    id2, "string2" etc
    }

3. Modify Makefile.in to contain
    RC_SRCS = rsrc.rc

(*) Do I need add other languages or do I let translators add their own? If
I look at programs\start vs programs\winecfg, one has 18 languages and one
has 14, so I am not quite sure what to do here

Thanks!
