with --nofork [--fork]
.. option:: --n <processes>
Max number of concurrent processes [6]
.. option:: --force
Force drawing of graphs that are not usually drawn due to options
in the config file. Can be negated with --noforce [--noforce]

.. option:: --only-fqn <FQN>
For internal use with CGI graphing. Graph only a single fully

.. option:: --log-file | -l
Output log file. (used for CGI graphing)
.. option:: --day

[--sumyear]
.. option:: --pinpoint <start,stop>
Create custom-graphs. <start,stop> is the time in the standard unix

.. option:: --size_x <pixels>
Sets the X size of the graph in pixels [175]
.. option:: --size_y <pixels>
Sets the Y size of the graph in pixels [400]
.. option:: --lower_limit <lim>
Sets the lower limit of the graph
.. option:: --upper_limit <lim>
