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