[Spread-users] where can I find the "s" and "r" programs?

When googling to resolve the high retrans rate (~50%) of one of my
spread daemons, I found this in an old post in this mailing list
(http://lists.spread.org/pipermail/spread-users/2001-August/000263.html):

We have some programs you can find in the distribution
called "s" and "r" that can show what happens in terms of low level issues on
your network. s and r are not part of the Spread toolkit really but they can be
useful to us when we try to see if there is a problem on the udp level.
Maybe you can poke a bit there.

I checked the source and binary distribution of spread-4.0.0, but
found nothing named as "s" or "r".  Where can I find them?  Or are
there better utils to use to analyze network these days?
