i18n directory overview:

closure/ - closure files we use for ruleset generation
src/ - source files
spec/ - spec files for stuff in src directory
generate.sh - runs src scripts on closure dir and stores output in locale dir
update-closure.sh - downloads the latest version of closure files from public git repo

The closure files (maintained by Shanjian Li (shanjian)) change very rarely, so we don't need to regenerate locale files very often.
