  13  * sends a meta-file with the MIME type 'application/x-external-editor'
  14  * to the client. The user has to associate that MIME type with
  15  * a helper application (a reference implementation in Perl
  16  * can be found in extensions/ee), which will launch the editor,
  17  * and save the modified data back to the server.
