+# This backports the Ruby 1.9 String interpolation syntax to Ruby 1.8.
+#
+# This backport has been shipped with I18n for a number of versions. Meanwhile
+# Rails has started to rely on it and we are going to move it to ActiveSupport.
+# See https://rails.lighthouseapp.com/projects/8994/tickets/6013-move-19-string-interpolation-syntax-backport-from-i18n-to-activesupport
+#
+# Once the above patch has been applied to Rails the following code will be
+# removed from I18n.

+    # % uses self (i.e. the String) as a format specification and returns the
+    # result of applying it to the given arguments. In other words it interpolates
+    # the given arguments to the string according to the formats the string
+    # defines.
+    #
+    # There are three ways to use it:
+    #
+    # * Using a single argument or Array of arguments.
+    #
+    #   This is the default behaviour of the String class. See Kernel#sprintf for
+    #   more details about the format string.
+    #
+    #   Example:
+    #
+    #     "%d %s" % [1, "message"]
+    #     # => "1 message"
+    #
+    # * Using a Hash as an argument and unformatted, named placeholders.
+    #
+    #   When you pass a Hash as an argument and specify placeholders with %{foo}
+    #   it will interpret the hash values as named arguments.
+    #
+    #   Example:
+    #
+    #     "%{firstname}, %{lastname}" % {:firstname => "Masao", :lastname => "Mutoh"}
+    #     # => "Masao Mutoh"
+    #
+    # * Using a Hash as an argument and formatted, named placeholders.
+    #
+    #   When you pass a Hash as an argument and specify placeholders with %<foo>d
+    #   it will interpret the hash values as named arguments and format the value
+    #   according to the formatting instruction appended to the closing >.
+    #
+    #   Example:
+    #
+    #     "%<integer>d, %<float>.1f" % { :integer => 10, :float => 43.4 }
+    #     # => "10, 43.3"
