Rails plugin: Fast and easy localization of one-language applications. Adds UTF-8 support for Ruby + database. Modifies ActiveRecord errors + html error helpers, Date/Time helpers, locale time formats, to_currency, to_sentence
Update: Jesper shows the plugin in action at his website. Take a look!
So, the plugin tries to make Rails speak your language, with error messages in your langauge, and so on.
There are FIXMEs in the code, so you can just “patch in”, if this is up your alley.
