51 "*Default actions to be taken when the user asks to view a file.
52 To change the behaviour, you can either edit this variable or set
53 `gnus-uu-user-view-rules' to something useful.
57 To make gnus-uu use 'xli' to display JPEG and GIF files, put the
58 following in your .emacs file:
60 (setq gnus-uu-user-view-rules '((\"jpg$\\\\|gif$\" \"xli\")))
62 Both these variables are lists of lists with two string elements. The
63 first string is a regular expression. If the file name matches this
64 regular expression, the command in the second string is executed with
65 the file as an argument.
67 If the command string contains \"%s\", the file name will be inserted
68 at that point in the command string. If there's no \"%s\" in the
69 command string, the file name will be appended to the command string
72 There are several user variables to tailor the behaviour of gnus-uu to
73 your needs. First we have `gnus-uu-user-view-rules', which is the
74 variable gnus-uu first consults when trying to decide how to view a
75 file. If this variable contains no matches, gnus-uu examines the
76 default rule variable provided in this package. If gnus-uu finds no
77 match here, it uses `gnus-uu-user-view-rules-end' to try to make a
