"""
Rewrites language files in order to be consistent with en_us.

This will take every given language file and rewrite it to be in the same
order as the en_us file. Any keys which appear in the given file, but not
in en_us are removed.

Note, this is not intended to be a fool-proof tool, rather a quick way to
ensure language files are mostly correct.
