e9346447 79To change the behavior, you can either edit this variable or set
eec82323
LMI
80`gnus-uu-user-view-rules' to something useful.
81
82For example:
83
84To make gnus-uu use 'xli' to display JPEG and GIF files, put the
85following in your .emacs file:
86
87 (setq gnus-uu-user-view-rules '((\"jpg$\\\\|gif$\" \"xli\")))
88
89Both these variables are lists of lists with two string elements. The
90first string is a regular expression. If the file name matches this
91regular expression, the command in the second string is executed with
92the file as an argument.
93
94If the command string contains \"%s\", the file name will be inserted
95at that point in the command string. If there's no \"%s\" in the
96command string, the file name will be appended to the command string
97before executing.
98
e9346447 99There are several user variables to tailor the behavior of gnus-uu to
eec82323
LMI
100your needs. First we have `gnus-uu-user-view-rules', which is the
101variable gnus-uu first consults when trying to decide how to view a
102file. If this variable contains no matches, gnus-uu examines the
103default rule variable provided in this package. If gnus-uu finds no
104match here, it uses `gnus-uu-user-view-rules-end' to try to make a
105match."
