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