    """Install a _() function using the given translation domain.

    Given a translation domain, install a _() function using gettext's
    install() function.

    The main difference from gettext.install() is that we allow
    overriding the default localedir (e.g. /usr/share/locale) using
    a translation-domain-specific environment variable (e.g.
    NOVA_LOCALEDIR).

    Note that to enable lazy translation, enable_lazy must be
    called.
