Monolingual

Monolingual is a tool that you can use to eliminate unused language resources from your system.

If you're not familiar with languages like Albanian, Bengali, Bulgarian, Nepalese, Tagalog, Tibetan, or Vietnamese... then why are you wasting disk space on them?

Monolingual doesn't just eliminate language resources, but can also get rid of keyboard setups used in other countries (Korean, Traditional Chinese, Japanese) and earlier computer architectures (PowerPC G5 and earlier).
