module Mobility
  module Backend
=begin

Stores translated attribute as a column on the model table.

To use this backend, ensure that the model table has columns named
+<attribute>_<locale>+ for every locale in +I18n.available_locales+.

==Backend Options

There are no options for this backend. Also, the +locale_accessors+ option will
be ignored if set, since it would cause a conflict with column accessors.
