This is mrouted version 3.5, with the route-change notification hook from

mrouted-3.5n.  This is being splatted onto the head rather than properly
imported thanks to the ``delete trailing whitespace'' screw.  This code is
now actively working in an operational environment (the DARTNET) so I
have some confidence that the basic functionality actually works.

+.I map-mbone
 attempts to display all multicast routers that are reachable from the multicast
-router
-.Ar router .
-If not specified on the command line, the default
-.Ar router
-is the local host.
-.Nm
-traverses neighboring multicast routers by sending the 
-.Dv ASK_NEIGHBORS 
-.Tn IGMP
-message to each router. If this multicast router responds, the version
-number and a list of their neighboring multicast router addresses is
-part of that response. If the responding router has recent multicast
-version number, then

+If not specified on the command line, the default multicast
+.I starting_router
+is the localhost. 
+.PP
+.I map-mbone
+traverses neighboring multicast routers by sending the ASK_NEIGHBORS IGMP
+message to the multicast starting_router. If this multicast router responds,
+the version number and a list of their neighboring multicast router addresses is
+part of that response. If the responding router has recent multicast version
+number, then 
+.I map-mbone
 requests additional information such as metrics, thresholds, and flags from the
 multicast router. For each new occurrence of neighboring multicast router in 
 the reply and provided the flooding option has been selected, then 
-.Nm
+.I map-mbone
 asks each of this multicast router for a list of neighbors. This search
 for unique routers will continue until no new neighboring multicast routers
 are reported.

-.It Fl d Ar debuglevel
-This sets the debug level to
-.Ar debuglevel .
-When the debug level is greater than the default value of 0,
-additional debugging messages are printed. Regardless of the debug

+.PP
+"\-d" option sets the debug level. When the debug level is greater than the
+default value of 0, addition debugging messages are printed. Regardless of
+the debug level, an error condition, will always write an error message and will
+cause 
 .I map-mbone
 to terminate.
 Non-zero debug levels have the following effects:
-.Bl -tag -width "level 3"
-.It level 1
+.IP "level 1"
 packet warnings are printed to stderr.
-.It level 2
+.IP "level 2"
 all level 1 messages plus notifications down networks are printed to stderr.
-.It level 3
+.IP "level 3"
 all level 2 messages plus notifications of all packet
 timeouts are printed to stderr.
-.El
-.It Fl f
-This option enables flooding. Flooding allows
-.Nm
-to perform recursive search
-of neighboring multicast routers and is enabled by default when an
-initial
-.Ar router
-is not specified.
-.It Fl g
-This option enables graphing in GraphEd format.
-.It Fl n
-This option disables the DNS lookup for the multicast routers' names.
-.It Fl r Ar retries
-This options sets the neighbor query retry limit to
-.Ar retries .
-The default is one retry.
-.It Fl t Ar timeout
-This option sets the number of seconds to wait for a neighbor query
-reply before retrying. The default timeout is two seconds.
