91 # an Array containing the values to be substituted. See Kernel::sprintf for details of the
92 # format string. This is the default behavior of the String class.
93 # * arg: an Array or other class except Hash.
94 # * Returns: formatted String
96 # (e.g.) "%s, %s" % ["Masao", "Mutoh"]
98 # Also you can use a Hash as the "named argument". This is recommanded way for Ruby-GetText
99 # because the translators can understand the meanings of the msgids easily.
