-/**
- * The DateLocale class is a container and base class for all
- * localised date strings used by YAHOO.util.Date. It is used
- * internally, but may be extended to provide new date localisations.
- *
- * To create your own DateLocale, follow these steps:
- * <ol>
- * <li>Find an existing locale that matches closely with your needs</li>
- * <li>Use this as your base class. Use YAHOO.util.DateLocale if nothing
- * matches.</li>
- * <li>Create your own class as an extension of the base class using
- * YAHOO.lang.merge, and add your own localisations where needed.</li>
- * </ol>
- * See the YAHOO.util.DateLocale['en-US'] and YAHOO.util.DateLocale['en-GB']
- * classes which extend YAHOO.util.DateLocale['en'].
- *
- * For example, to implement locales for French french and Canadian french,
- * we would do the following:
- * <ol>
- * <li>For French french, we have no existing similar locale, so use
- * YAHOO.util.DateLocale as the base, and extend it:
- * <pre>
- * YAHOO.util.DateLocale['fr'] = YAHOO.lang.merge(YAHOO.util.DateLocale, {
- * a: ['dim', 'lun', 'mar', 'mer', 'jeu', 'ven', 'sam'],
- * A: ['dimanche', 'lundi', 'mardi', 'mercredi', 'jeudi', 'vendredi', 'samedi'],
- * b: ['jan', 'fév', 'mar', 'avr', 'mai', 'jun', 'jui', 'aoû', 'sep', 'oct', 'nov', 'déc'],
- * B: ['janvier', 'février', 'mars', 'avril', 'mai', 'juin', 'juillet', 'août', 'septembre', 'octobre', 'novembre', 'décembre'],
- * c: '%a %d %b %Y %T %Z',
- * p: ['', ''],
- * P: ['', ''],
- * x: '%d.%m.%Y',
- * X: '%T'
- * });
- * </pre>
- * </li>
- * <li>For Canadian french, we start with French french and change the meaning of \%x:
- * <pre>
- * YAHOO.util.DateLocale['fr-CA'] = YAHOO.lang.merge(YAHOO.util.DateLocale['fr'], {
- * x: '%Y-%m-%d'
- * });
- * </pre>
- * </li>
- * </ol>
- *
- * With that, you can use your new locales:
- * <pre>
- * var d = new Date("2008/04/22");
- * YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr");
- * </pre>
- * will return:
- * <pre>
- * mardi, 22 avril == 22.04.2008
- * </pre>
- * And
- * <pre>
- * YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr-CA");
- * </pre>
- * Will return:
- * <pre>
- * mardi, 22 avril == 2008-04-22
- * </pre>
