R18n is an i18n tool. It isn’t a yet another Rails plug-in. R18n has a core gem and plugins for the Merb framework and desktop applications. It can format numbers and time to the rules of the user locale. Translations are stored in YAML format with procedures and pluralization (“1 comment”, “5 comments”). It has special support for countries with two official languages (exUSSR, China) and translation for commons words, like “OK”, “Cancel”, etc.
