= 5.3 * License: MIT * Version: 1.0 * Author: Tobias Diekershoff * * About * ===== * * This addon will allow you to enter a date/time period during which * all your ~friendica visitors from the web will be redirected to a page * you can configure in the admin panel as well. * * Calls to the API and the communication with other ~friendica nodes is * not effected from this addon. * * If you enter a period the current date would be affected none of the * currently logged in users will be effected as well. But if they log * out they can't login again. That way you dear admin can double check * the entered time periode and fix typos without having to hack the * database directly. * * Requirements * ============ * * THIS ADDON REQUIRES PHP VERSION 5.3 OR HIGHER. * * License * ======= * * Permission is hereby granted, free of charge, to any person obtaining a copy * of this software and associated documentation files (the "Software"), to deal * in the Software without restriction, including without limitation the rights * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell * copies of the Software, and to permit persons to whom the Software is * furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included in * all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
