| dired-guess-shell-alist-user's value is shown below.
| 
| Documentation:
| User-defined alist of rules for suggested commands.
| These rules take precedence over the predefined rules in the variable
| `dired-guess-shell-alist-default' (to which they are prepended).
| 
| Each element of this list looks like
| 
|     (REGEXP COMMAND...)
| 
| where each COMMAND can either be a string or a lisp expression that evaluates
| to a string.  If several COMMANDs are given, the first one will be the default
| and the rest will be added temporarily to the history and can be retrieved
| with M-x previous-history-element (M-p) .
| 
| You can set this variable in your ~/.emacs.  For example, to add rules for
| `.foo' and `.bar' files, write
| 
|  (setq dired-guess-shell-alist-user
|        (list (list "\\.foo\\'" "FOO-COMMAND");; fixed rule
|               ;; possibly more rules ...
|               (list "\\.bar\'";; rule with condition test
|                     '(if condition
|                           "BAR-COMMAND-1"
|                         "BAR-COMMAND-2"))))
| 
| You can customize this variable.
| 
| Defined in `dired-x'.
| 
| Value:
| (("\\.pdf$" "xpdf * &")
|  ("\\.pdf\\.gz$" "zxpdf * &")
|  ("\\.dvi$" "xdvi * &")
|  ("\\.ps$" "gv --spartan * &")
|  ("\\.eps$" "gv --spartan * &")
|  ("\\.ps\\.gz$" "gv --spartan * &")
|  ("\\.rtf$" "ted * &")
|  ("\\.jpeg$" "display * &")
|  ("\\.jpg$" "display * &")
|  ("\\.gif$" "display * &")
|  ("\\.png$" "display * &"))
