====== [UK] UserFile Killer ======

Deletes (kills) certain users from your user file.  The criteria are: not
having called for a certain number of days, less than a certain number of
times called, a certain security level or a combination of these three.

Parameters to use:

    -D<# of days>   Removes all users that haven't called for <# of days>
    -C<calls>       Removes all users that have called less than <calls>
                    times.
    -L<evel>        Specifies a specific security level for the User
                    Killer to work on.

Combining these three parameters, will remove all users that have called less than <calls> times and haven't called for <# of days>, and that only have the specified <level>.  This option comes in handy to remove all users that have called just once, but without removing your new users or
users with another security level.
