  53   "*Default actions to be taken when the user asks to view a file.
  54 To change the behaviour, you can either edit this variable or set
  55 `gnus-uu-user-view-rules' to something useful.
  56
  57 For example:
  58
  59 To make gnus-uu use 'xli' to display JPEG and GIF files, put the
  60 following in your .emacs file:
  61
  62   (setq gnus-uu-user-view-rules '((\"jpg$\\\\|gif$\" \"xli\")))
  63
  64 Both these variables are lists of lists with two string elements. The
  65 first string is a regular expression. If the file name matches this
  66 regular expression, the command in the second string is executed with
  67 the file as an argument.
  68
  69 If the command string contains \"%s\", the file name will be inserted
  70 at that point in the command string. If there's no \"%s\" in the
  71 command string, the file name will be appended to the command string
  72 before executing.
  73
  74 There are several user variables to tailor the behaviour of gnus-uu to
  75 your needs. First we have `gnus-uu-user-view-rules', which is the
  76 variable gnus-uu first consults when trying to decide how to view a
  77 file. If this variable contains no matches, gnus-uu examines the
  78 default rule variable provided in this package. If gnus-uu finds no
  79 match here, it uses `gnus-uu-user-view-rules-end' to try to make a
  80 match.")
