122 # If the format specification contains more than one substitution, then arg must be
123 # an Array containing the values to be substituted. See Kernel::sprintf for details of the
124 # format string. This is the default behavior of the String class.
125 # * arg: an Array or other class except Hash.
126 # * Returns: formatted String
128 # (e.g.) "%s, %s" % ["Masao", "Mutoh"]
130 # Also you can use a Hash as the "named argument". This is recommanded way for Ruby-GetText
131 # because the translators can understand the meanings of the msgids easily.
132 # * hash: {:key1 => value1, :key2 => value2, ... }
133 # * Returns: formatted String
