Language file in Provisioning module

[tulsi]

I implemented a provisioning module. The client area is completely modified through the module. I would like to add translations to the client area part.  My module folder structure is: modules/servers/mymodule/mymodule.php

I have included the lang folder like that: modules/servers/mymodule/lang/english.php. Now I am not sure how can I access translations in my smarty files ({$LANG.load}). Like addon modules' _output method, provisioning module's _clientarea do not have the variable like $var['_lang].

english.php content eg:

$_ADDONLANG['load'] = "Load";

Any help would be appreciated. Thank you.
