78To change the behaviour, you can either edit this variable or set
79`gnus-uu-user-view-rules' to something useful.
80
81For example:
82
83To make gnus-uu use 'xli' to display JPEG and GIF files, put the
84following in your .emacs file:
85
86 (setq gnus-uu-user-view-rules '((\"jpg$\\\\|gif$\" \"xli\")))
87
88Both these variables are lists of lists with two string elements. The
89first string is a regular expression. If the file name matches this
90regular expression, the command in the second string is executed with
91the file as an argument.
92
93If the command string contains \"%s\", the file name will be inserted
94at that point in the command string. If there's no \"%s\" in the
95command string, the file name will be appended to the command string
96before executing.
97
98There are several user variables to tailor the behaviour of gnus-uu to
99your needs. First we have `gnus-uu-user-view-rules', which is the
100variable gnus-uu first consults when trying to decide how to view a
101file. If this variable contains no matches, gnus-uu examines the
102default rule variable provided in this package. If gnus-uu finds no
103match here, it uses `gnus-uu-user-view-rules-end' to try to make a
104match."
