Here's the thing: I'm building an app which should be fully localized.
I managed to create stores to load captions according to a language defined as a get parameter (yay).

My problem is that apparently the right solution to translate texts from ExtJS itself is to set a locale in the config of the build command. Except I want to build 1 app for n languages, not n app for n languages.

Apparently it's doable by adding the following in the html:
HTML Code:
<script type="text/javascript" src="%EXT_PATH%/packages/ext-locale/build/ext-locale-%LANG%.js"></script>
How can I modify the html generated by ExtJS to append such markup?

Thanks in advance,
