This file documents the necessary procedure for adding a new
language to the list of languages that Wine can display system
menus and forms in. Currently at least the following languages
are still missing:
<simplelist columns="5" type="horiz">
<member>Bulgarian</member>
<member>Chinese</member>
<member>Greek</member>
<member>Icelandic</member>
<member>Japanese</member>
<member>Romanian</member>
<member>Croatian</member>
<member>Turkish</member>
<member>Slovanian</member>
</simplelist>

<emphasis>I hope I got all the places where changes are
needed. If you see any place missing from the list,
submit a patch to this file please. Also note that
re-organization of the source code might change the list of
places.</emphasis>

To add a new language you need to be able to translate the
relatively few texts, of course. You will need very little
knowledge of programming, so you have almost no excuses for
not adding your language, right? We should easily be able to
support 20 languages within a few months, get going! Apart
from re-compilation it'll take you about an hour or two.

To add a new language to the list of languages that Wine can
handle you must...

<para>
Look in <filename>ole/ole2nls.c</filename> if your
language is already incorporated in the <varname>static
const struct NLS_langlocale</varname>. If not: find the
appropriate entries in
<filename>include/winnls.h</filename> and add them to the
list.

Edit <filename>misc/main.c</filename> variable

<para>
Create a new file
<filename>dlls/commdlg/cdlg_XX.rc</filename> (where
<literal>XX</literal> is your language abbreviation)
containing all menus. Your best bet is to copy
<filename>cdlg_En.rc</filename> and start translating.
There is no real need to know how the internal structure
of the file, as you only need to translate the text within
quotes.
</para>
<para>
In menus, the character "&amp;" means that the next
character will be highlighted and that pressing that
letter will select the item. You should place these
"&amp;" characters suitably for your language, not just
copy the positions from (say) English. In particular,
items within one menu should have different highlighted
letters.

Edit <filename>dlls/commdlg/rsrc.rc</filename> to contain
