e9346447 77To change the behavior, you can either edit this variable or set
eec82323
LMI
78`gnus-uu-user-view-rules' to something useful.
79
80For example:
81
82To make gnus-uu use 'xli' to display JPEG and GIF files, put the
83following in your .emacs file:
84
85 (setq gnus-uu-user-view-rules '((\"jpg$\\\\|gif$\" \"xli\")))
86
87Both these variables are lists of lists with two string elements. The
88first string is a regular expression. If the file name matches this
89regular expression, the command in the second string is executed with
90the file as an argument.
91
92If the command string contains \"%s\", the file name will be inserted
93at that point in the command string. If there's no \"%s\" in the
94command string, the file name will be appended to the command string
95before executing.
96
e9346447 97There are several user variables to tailor the behavior of gnus-uu to
eec82323
LMI
98your needs. First we have `gnus-uu-user-view-rules', which is the
99variable gnus-uu first consults when trying to decide how to view a
100file. If this variable contains no matches, gnus-uu examines the
101default rule variable provided in this package. If gnus-uu finds no
102match here, it uses `gnus-uu-user-view-rules-end' to try to make a
103match."
