Articles are marked as expirable automatically if the group has the
'auto-expire' property set to t.  You can set it for a group by typing
'G p' over the name of the group in the *Group* buffer and then adding
this property to the parameter list of the group:

    (auto-expire . t)

By default groups have no properties, so you will see 'nil' as their
property list:

    nil

You can replace this with a list that contains only a cons cell with
auto-expire:

    ((auto-expire . t))

You can enable multiple group properties, e.g.:

    ((auto-expire . t)
