Anything wrong with FAQ 4.6?

After our discussion on "Disable mailcap support"[1] in 2003 I have
added `mm-enable-external'.  Please elaborate if that's not
sufficient.

,----[ (info "(emacs-mime)Display Customization") ]
| `mm-enable-external'
|      Indicate whether external MIME handlers should be used.
| 
|      If `t', all defined external MIME handlers are used.  If `nil',
|      files are saved to disk (`mailcap-save-binary-file').  If it is
|      the symbol `ask', you are prompted before the external MIME
|      handler is invoked.
| 
|      When you launch an attachment through mailcap (*note mailcap::) an
|      attempt is made to use a safe viewer with the safest options--this

|      way (command line or double-clicking).  Anyhow, if you want to be
|      sure not to launch any external programs, set this variable to
|      `nil' or `ask'.

Bye, Reiner.
