I'd love to see a proper port of localepurge... I'm currently using the version hacked to use pcregrep, instead. Localepurge frees up a nice 15 MBs' worth of locales that I will never use. (And it continues to free up space by purging locales after a program is installed.) But the problem with the currently available, it assumes the user is using en_GB and, by default, only chooses to keep: en, en_GB and en_US locales.
