Monolingual

Monolingual is a program for removing unnecessary language resources from Mac OS X, in order to reclaim several hundred megabytes of disk space. It requires at least Mac OS X 10.5 (Leopard) and also works on Mac OS X 10.6 (Snow Leopard) and Mac OS X 10.7 (Lion). Version 1.3.9 is the last version for Mac OS X 10.4 (Tiger). You can use Monolingual to reclaim disk space on your personal Mac or on your Mac dedicated servers.

I don't know about you, but I use my computer in only one (human) language — English. And I'm willing to bet that you do too, albeit perhaps not English. So why do you have a bunch of localization files for the Mac OS X operating system filling up your hard drive? Enter Monolingual — a handy utility for reclaiming your space for more useful things… like international mp3 files, email or whatever you like.
