Controlling Amd
===============

   It is sometimes desirable or necessary to exercise external control
over some of Amd's internal state.  To support this requirement, Amd
implements an RPC interface which is used by the "Amq" program.  A
variety of information is available.

   Amq generally applies an operation, specified by a single letter
option, to a list of mount points.  The default operation is to obtain
statistics about each mount point.  This is similar to the output shown
above but includes information about the number and type of accesses to
each mount point.
