Possible values are lists of integers, like <code>2</code> (groups of 2 items) or <code>1,2</code> (alternate groups of 1 and 2 items). Otherwise, the value is evaluated on each loop and <code>break</code> happens as soon as it changes. Note that <code>string</code> must be enclosed in *double* quotes.</dd>
