/**
* This class encapsulates "magic words" such as #redirect, __NOTOC__, etc.
- * Usage:
- * if (MagicWord::get( 'redirect' )->match( $text ) )
+ *
+ * @par Usage:
+ * @code
+ * if (MagicWord::get( 'redirect' )->match( $text ) ) {
+ * // some code
+ * }
+ * @endcode
*
* Possible future improvements:
* * Simultaneous searching for a number of magic words
* Please avoid reading the data out of one of these objects and then writing
* special case code. If possible, add another match()-like function here.
*
- * To add magic words in an extension, use the LanguageGetMagic hook. For
- * magic words which are also Parser variables, add a MagicWordwgVariableIDs
+ * To add magic words in an extension, use $magicWords in a file listed in
+ * $wgExtensionMessagesFiles[].
+ *
+ * @par Example:
+ * @code
+ * $magicWords = array();
+ *
+ * $magicWords['en'] = array(
+ * 'magicwordkey' => array( 0, 'case_insensitive_magic_word' ),
+ * 'magicwordkey2' => array( 1, 'CASE_sensitive_magic_word2' ),
+ * );
+ * @endcode
+ *
+ * For magic words which are also Parser variables, add a MagicWordwgVariableIDs
* hook. Use string keys.
