Translating an unreleased package

The following notice appear on: http://localize.drupal.org/issues under the heading: "Project or release not listed?"

Because your development code can change from minute to minute, we are only parsing released packages, so translators can focus on shipped software to translate.

I understand the rationale behind this policy. However. several of my Norwegian D7 sites depends on an unreleased package (Notify).

What is the recommended practice for translating an unreleased package?

Update: Figured it out myself: You create a .po-file and upload it to your site using the interface provided by the Localization update (l10n update) module.
