- * Support for external editors to modify both text and files
- * in external applications. It works as follows: MediaWiki
- * sends a meta-file with the MIME type 'application/x-external-editor'
- * to the client. The user has to associate that MIME type with
- * a helper application (a reference implementation in Perl
- * can be found in extensions/ee), which will launch the editor,
- * and save the modified data back to the server.
