118 # an Array containing the values to be substituted. See Kernel::sprintf for details of the
119 # format string. This is the default behavior of the String class.

121 # * Returns: formatted String
123 # (e.g.) "%s, %s" % ["Masao", "Mutoh"]
125 # Also you can use a Hash as the "named argument". This is recommanded way for Ruby-GetText
126 # because the translators can understand the meanings of the msgids easily.
