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