   plot_blif [-k] [-r] [-i] [-g WxH+X+Y] [-n name]
 
     The plot_blif command creates a window with an abstract representation
     of the network, at its current level of optimization, labeling all
     nodes, including primary inputs and outputs.  Vectors are used to show
     relationships between the various nodes.  Latches are not printed expli-
     citly.  The network is drawn as an acyclic combinational circuit.
     Labelled arrows indicate the locations of the latches.
 
     The -k option "kills" (closes) the most recent plot window with the
     current network name.
 
     The -r option replaces the contents of an existing plot window with the
     current network structure.  This is useful if the network has been modi-
     fied since it was last plotted.  If no plot window is open with the
     current network name, the command has no effect.
 
     The -i option forces a plot of the internal network structure used by
     SIS.  The default is to plot the structure corresponding to the
     write_blif command.  The primary difference in the internal structure is
     in how primary outputs are handled.
 
     The -g option allows an initial geometry to be specified for the plot
     window.
 
     The -n option allows "name" to be used for the plot window name instead
     of the network name.
