+ # Translates, pluralizes and interpolates a given key using a given locale,

+ #
+ # *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>
+ # or <tt>default</tt> if no translations for <tt>:foo</tt> and <tt>:bar</tt> were found.
+ # I18n.t :foo, :default => [:bar, 'default']

+ #
+ # This returns an array with the translations for <tt>:foo</tt> and <tt>:bar</tt>.
+ # I18n.t [:foo, :bar]
+ #
+ # Can be used with dot-separated nested keys:
