/* Dynamic Content HACK
 * 2003 Stefan Born
 *
 * Loads content in an existing page.
 *
 * call with: onClick="content.call('destination','url');" in input buttons
 * or <a href="javascript:content.call('destination','url');">click</a>
 *
 * where destination is the id of an existing DIV
 * and url a relative path with content.
 *
 * The URL should deliver a valid HTML-page with content in body.
 *
 * No further HTML Markup needed.
 *
 * FORM and A with target "_self" will be changed.
 *
 * Use it like You want. No warranty given.
 * Keeping this information intact would be very nice.
