def javascript_catalog(request, domain='djangojs', packages=None):
    """
    Returns the selected language catalog as a javascript library.

    Receives the list of packages to check for translations in the
    packages parameter either from an infodict or as a +-delimited
    string from the request. Default is 'django.conf'.

    Additionally you can override the gettext domain for this view,
    but usually you don't want to do that, as JavaScript messages
    go to the djangojs domain. But this might be needed if you
    deliver your JavaScript source from Django templates.
