Cool!  FriendStatus() looks like exactly what I want, but I can't find an 
example of it in use.

The Reference says that it "displays a message if hosts that normally have a 
cfengine protocol connection with the current host have not connected for 
more than than specified number of hours", which is perfect. 

I do have a couple of questions on it, though:   First, how does it determines 
that a host "normally" has a connection?  Should I be somehow providing it 
with a list?  Does it start watching for a given host after the first time it 
sees it connect?  

Secondly, how can I get the name of the host that generates the alert?  I am 
assuming that my alert will simply contain the alert string, as per usual, 
which will alert me to the fact that *something* is late, but not exactly 
who.   

Forgive me for firing of questions to the list right away, but the nature of 
this animal seems to make exploratory testing somewhat tricky.  You mentioned 
something about an advanced tutorial that might cover FriendStatus in a post 
last April (http://lists.gnu.org/archive/html/help-cfengine/2004-04/
msg00110.html), but I couldn't find it....
