| | 3 | * Extension of TinyMCE GoogleSpell class for Wordpress |
| | 4 | * |
| | 5 | * WP_GoogleSpell extends TinyMCE's GoogleSpell class. It overrides the way in which the |
| | 6 | * http request to google is executed and uses WP_Http instead of curl/fsockopen. |
| | 7 | * |
| | 8 | * In order to use this class the "general.engine" value in config.php |
| | 9 | * (wp-includes/js/tinymce/plugins/spellchecker) needs to be set to "WP_GoogleSpell" |
| | 10 | * instead of "GoogleSpell". |
