Asset pipeline and depending on files outside of /app/assets directory

Hi,

I’m generating a js file with all translations from Rails I18n backend
and
the issue is that when I change translations in config/locales
directory,
the js file is not recompiled in development env. Is there any way to
tell
asset pipeline/sprockets that this particular js file depends on all
files
in config/locales directory?

Cheers,
Szymon
