/**
 * This factory interface allows to produce {@link FoldManager}

 * <br>
 * It is intended for xml layer registration
 * into the following folder in the system FS:
 * <pre>
 *     Editors/&lt;mime-type&gt;/FoldManager
 * </pre>
 * For example java fold manager factories should be registered in
 * <pre>
 *     Editors/text/x-java/FoldManager
 * </pre>
 *
 * <p>
 * The factories present in the folder can be sorted by using standard
 * <a href="@org-openide-modules@/org/openide/modules/doc-files/api.html#how-layer">
 * Layer Ordering</a>.
 * <br>
 * The fold manager of factory A registered prior factory B produces
 * folds with higher priority than those from fold manager of factory B.
 * <br>
 * If two folds would overlap the one with higher priority
 * will be visible - see {@link FoldManager} for more details.
