connections. Including a flag to instead output a sequence of tcpdrop(8)
invocations that would accomplish the same thing, which is convenient for
scripting.

address families, rather than failing silently.
o) When cross-referencing httpd(8), do not explicitly specify the apache2 port,
since the example in question is generic.
