This package presents the System Status GUI, which shows the status of
all of the servers running in the system. It polls
a Net Manager process in the V.O.C.A.L. phone system,
which discovers which servers are up and which are down. The Net
Manager process returns the status of the system in answer to
each polling request, and the System Status code builds a JTree
showing the servers in a tree rooted at the hostname of each server.
The Start and Stop buttons in the GUI cause requests to be sent to
the Net Manager that start or stop the process represented by the
node currently selected in the JTree.
