/**
 * @file
 * API documentation for Wysiwyg module.
 *
 * To implement a "Drupal plugin" button, you need to write a Wysiwyg plugin:
 * - Implement hook_wysiwyg_include_directory() to register the directory
 *   containing plugin definitions.
 * - In each plugin definition file, implement hook_INCLUDE_plugin().
 * - For each plugin button, implement a JavaScript integration and an icon for
 *   the button.
 *
 * @todo Icon: Recommended size and type of image.
 *
 * For example implementations you may want to look at
 * - Image Assist (img_assist)
 * - Teaser break plugin (plugins/break; part of WYSIWYG)
 * - IMCE (imce_wysiwyg)
