/** Create a JAR file with locale variants.
 * Whenever files are found which should be localized, or are the result
 * of localization, places them in separate JAR files named according to the locale,
 * in a <samp>locale/</samp> subdirectory of the directory containing the master JAR.
 * Each sub-JAR gets a manifest which just has some informational tags
 * indicating its purpose (locale and branding):
 * <code>X-Informational-Archive-Locale</code> and/or <code>X-Informational-Archive-Branding</code>.
 * The values may be e.g. <code>ja</code> or <code>f4j_ce</code>; or <code>-</code>
 * if there is no suffix for this JAR.
 * You can control the available locales; brandings; and set of files which should
 * always be considered part of the localizable base kit.
 * You can use the "branding" and "locale" subelements to control the branded
 * and localized .jar files that will be produced.  Also, you can set the global
 * properties "locjar.brands" and "locjar.locales" to comma-separated
 * lists of branding or locale identifiers so that NetBeans-based projects can
 * brand or localize NetBeans without having to maintain modified versions of all
 * the individual Ant scripts
 * Originally this Ant task didn't recognize files below a directory with the
 * same name as a locale as being localized.  Now it does so by default.
 * <p>Based on <code>&lt;zip&gt;</code> and <code>&lt;jar&gt;</code> tasks in Ant,
 * but not feasible to simply subclass or compose them.
