# RUR (Relationally Universal Ruby) is a Ruby relational algebra DSL 
# that compiles to SQL, allowing you to write complex
# queries without leaving your favorite language. It is going to be a nice
# Ruby-like replacement of SQL in the same manner CoffeeScript is a
# Ruby-like replacement of JavaScript. It will use all the features
# found in a modern RDBMS (views, temp views, constraints, triggers, functions,
# etc) without being tightly coupled to one particular implementation.
#
# Unlike ActiveRecord, which maps tables to classes, RUR maps relations to
# objects.

This is how we test that all translation keys match up between locales.

Stuff that only goes in one locale (such as an admin section) or that can't be translated yet (if you use external translators) can simply go in files that don't match the path "config/locales/??.yml", like "config/locales/wip.fo.yml".
