* Format---Uses <i>str</i> as a format specification, and returns the result
|

|
* of applying it to <i>arg</i>. If the format specification contains more than
|
||
|
* one substitution, then <i>arg</i> must be an <code>Array</code> containing
|
||
|
* the values to be substituted. See <code>Kernel::sprintf</code> for details
|
||
|
* of the format string.
