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