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

Shell archives are an archaic method of bundling files for distribution

unpack it. You can browse the archive buffer using \\[scroll-other-window].
If you are unsure what to do, please answer \"no\"."
