a while ago, someone posted the shell-script below to provide the capability
to subscribe or unsubscribe to a news-group with a command. If you should
ever give the command SS without an argument, your .newsrc will get trashed
completely. I can't give you a fix, even though I assume it is simple to
the UN*X wizzard, which I am not. (it needs some checking for the presence
of parameters) - but I want to warn you all ASAP, rather than make you wait
until I figure it out with the help of some manuals.
