+To change the behavior, you can either edit this variable or set
+`gnus-uu-user-view-rules' to something useful.
+
+For example:
+
+To make gnus-uu use `xli' to display JPEG and GIF files, put the
+following in your .emacs file:
+
+ (setq gnus-uu-user-view-rules \\='((\"jpg$\\\\|gif$\" \"xli\")))
+
+Both these variables are lists of lists with two string elements. The
+first string is a regular expression. If the file name matches this
+regular expression, the command in the second string is executed with
+the file as an argument.
+
+If the command string contains \"%s\", the file name will be inserted
+at that point in the command string. If there's no \"%s\" in the
+command string, the file name will be appended to the command string
+before executing.
+
+There are several user variables to tailor the behavior of gnus-uu to
+your needs. First we have `gnus-uu-user-view-rules', which is the
+variable gnus-uu first consults when trying to decide how to view a
+file. If this variable contains no matches, gnus-uu examines the
+default rule variable provided in this package. If gnus-uu finds no
+match here, it uses `gnus-uu-user-view-rules-end' to try to make a
+match."

+;;
+;; The second parameter is the state of the list of articles, and can
+;; have four values: `first', `middle', `last' and `first-and-last'.
+;;
+;; The function should return a list. The list may contain the
+;; following symbols:
+;; `error' if an error occurred
+;; `begin' if the beginning of an encoded file has been received
+;; If the list returned contains a `begin', the first element of
+;; the list *must* be a string with the file name of the decoded

+;; `middle' if the article was a body part of an encoded file
+;; `wrong-type' if the article was not a part of an encoded file
