 /**
- * @mainpage OMP API Reference
- *
- * Welcome to the OMP API Reference. This resource contains documentation
- * generated automatically from the OMP source code.
- *
- * The design of Open %Monograph press is heavily structured for
- * maintainability, flexibility and robustness. Those familiar with Sun's
- * Enterprise Java Beans technology or the Model-View-Controller (MVC) pattern
- * will note many similarities.
- *
- * As in a MVC structure, data storage and representation, user interface
- * presentation, and control are separated into different layers. The major
- * categories, roughly ordered from "front-end" to "back-end," follow:
- * - Smarty templates, which are responsible for assembling HTML pages to
- *   display to users;
- * - Page classes, which receive requests from users' web browsers, delegate
- *   any required processing to various other classes, and call up the
- *   appropriate Smarty template to generate a response;
- * - Controllers, which implement reusable pieces of content e.g. for AJAX
- *   subrequests.
- * - Action classes, which are used by the Page classes to perform non-trivial
- *   processing of user requests;
- * - Model classes, which implement PHP objects representing the system's
- *   various entities, such as Users, Monographs, and Presses;
- * - Data Access Objects (DAOs), which generally provide (amongst others)
- *   update, create, and delete functions for their associated Model classes,
- *   are responsible for all database interaction;
- * - Support classes, which provide core functionalities, miscellaneous common
- *
- * As the system makes use of inheritance and has consistent class naming
- * conventions, it is generally easy to tell what category a particular class
- * falls into.
- * For example, a Data Access Object class always inherits from the DAO class,
- * has a Class name of the form [Something]%DAO, and has a filename of the form
- * [Something]%DAO.inc.php.
- *
- * To learn more about developing OMP, there are several additional resources
- * that may be useful:
- * - The docs/README document
- * - The PKP support forum at https://forum.pkp.sfu.ca
