-v Verbose mode. Multiple -v options cause more verbosity.
-d Debug mode. Alias for -v.
-dot Generate output using 'dot' graph layout tool.
-vcg Generate output using 'vcg' graph layout tool.
-ps Generate PostScript format output.
-gif Generate GIF format output.
-png Generate PNG format output.
-o <out> Prefix for output filenames.
This program generates a graph of the state machines as defined in the
state_transitions and mode_transitions tables in the database. This
graph is generated from the current in the actual database, and is
always current. By default, output will be generated with the 'dot'
tool, and will be saved into the "". If both -dot and -vcg are
specified, Output is saved into images named "" and

always current. The -dot and -vcg options determine the layout tool(s)
used for generating the graphs. The -ps, -gif, and -png options
determine the format of the output images. If no layout options are
given, dot will be used. If no format options are given, ps will be used.
Output will be saved into <out>.{ps|gif|png}, depending on the format(s)
requested. When both -dot and -vcg are specified, output will be in
<out>-{dot,vcg}.{ps|gif|png}. When -o is not given, <out> defaults to
'$defprefix'. If an output file exists, it will be overwritten.
stategraph will show state machine diagrams for all operational modes
by default, or for a subset by specifying the desired modes on the
command line.
