Internacionalize Ext-js

Question

I'm doing a Ext-js application, I don't know how to internacionalize it.

How to do it?

I should read a .txt file that contains different strings? How to do it...?

We're using gettext[1]-like localization. All language-dependent strings are wrapped in tr() (like var msg = tr('SERVER_ADDRESS'); ).

tr itself looks like this:

function tr(msg)
{
    if (!_translation[msg]) {
        return msg;
    }
    return _translation[msg];
}

gettext po -files are converted to javascript code like this:

_translation = {
    SERVER_ADDRESS: 'The server address'
};

And this file is included as regular javascript source file.
