Make sense of language-pack-* vs. language-support-*

As of Ubuntu 5.10, language-specific add-ons fall into two categories. language-pack-*, which provides gettext translation data, and language-support-*, which provides "everything else" (including non-gettext translation data). We should consider whether we can make this distinction more meaningful, perhaps limiting language-support-* to non-translation data (e.g., authoring packages for spell checking, thesauruses, etc.)
