+    #
+    # *LOOKUP*
+    #
+    # Translation data is organized as a nested hash using the upper-level keys 
+    # as namespaces. <em>E.g.</em>, ActionView ships with the translation: 
+    # <tt>:date => {:formats => {:short => "%b %d"}}</tt>.
+    # 
+    # Translations can be looked up at any level of this hash using the key argument 
+    # and the scope option. <em>E.g.</em>, in this example <tt>I18n.t :date</tt> 
+    # returns the whole translations hash <tt>{:formats => {:short => "%b %d"}}</tt>.
+    # 
+    # Key can be either a single key or a dot-separated key (both Strings and Symbols 
+    # work). <em>E.g.</em>, the short format can be looked up using both:
+    #   I18n.t 'date.formats.short'
+    #   I18n.t :'date.formats.short'
+    # 
+    # Scope can be either a single key, a dot-separated key or an array of keys
+    # or dot-separated keys. Keys and scopes can be combined freely. So these
+    # examples will all look up the same short date format:
+    #   I18n.t 'date.formats.short'
+    #   I18n.t 'formats.short', :scope => 'date'
+    #   I18n.t 'short', :scope => 'date.formats'
+    #   I18n.t 'short', :scope => %w(date formats)
+    #
+    # *INTERPOLATION*
+    #
+    # Translations can contain interpolation variables which will be replaced by
+    # values passed to #translate as part of the options hash, with the keys matching
+    # the interpolation variable names. 
+    #
+    # <em>E.g.</em>, with a translation <tt>:foo => "foo {{bar}}"</tt> the option 
+    # value for the key +bar+ will be interpolated into the translation:
+    #   I18n.t :foo, :bar => 'baz' # => 'foo baz'
+    #
+    # *PLURALIZATION*
+    #
+    # Translation data can contain pluralized translations. Pluralized translations
+    # are arrays of singluar/plural versions of translations like <tt>['Foo', 'Foos']</tt>.
+    #
+    # Note that <tt>I18n::Backend::Simple</tt> only supports an algorithm for English 
+    # pluralization rules. Other algorithms can be supported by custom backends.
+    #
+    # This returns the singular version of a pluralized translation:
+    #   I18n.t :foo, :count => 1 # => 'Foo'
+    #
+    # These both return the plural version of a pluralized translation:
+    #   I18n.t :foo, :count => 0 # => 'Foos'
+    #   I18n.t :foo, :count => 2 # => 'Foos'
+    # 
+    # The <tt>:count</tt> option can be used both for pluralization and interpolation. 
+    # <em>E.g.</em>, with the translation 
+    # <tt>:foo => ['{{count}} foo', '{{count}} foos']</tt>, count will
+    # be interpolated to the pluralized translation:
+    #   I18n.t :foo, :count => 1 # => '1 foo'
+    #
+    # *DEFAULTS*
+    #
+    # This returns the translation for <tt>:foo</tt> or <tt>default</tt> if no translation was found:
+    #   I18n.t :foo, :default => 'default'
+    #
+    # This returns the translation for <tt>:foo</tt> or the translation for <tt>:bar</tt> if no 
+    # translation for <tt>:foo</tt> was found:
+    #   I18n.t :foo, :default => :bar
+    #
+    # Returns the translation for <tt>:foo</tt> or the translation for <tt>:bar</tt>
