 Optional command line arguments
 -------------------------------
 
-There are optional command line arguments for gprMax:
-
-===================== ======= ===========
-Argument              Type    Description
-===================== ======= ===========
-``-n``                integer number of times to run the input file. This option can be used to run a series of models, e.g. to create a B-scan with 60 traces: ``(gprMax)$ python -m gprMax user_models/cylinder_Bscan_2D.in -n 60``
-``-restart``          integer model number to start from. It would typically be used to restart a series of models from a specific model number, with the ``-n`` argument, e.g. to restart from A-scan 30 when creating a B-scan with 60 traces: ``(gprMax)$ python -m gprMax user_models/cylinder_Bscan_2D.in -n 15 -restart 45``
-``-task``             integer task identifier (model number) for job array on Open Grid Scheduler/Grid Engine (http://gridscheduler.sourceforge.net/index.html)'). It would typically be used with the ``-n`` argument, e.g. to create a B-scan.
-``-mpi``              integer number of MPI tasks, i.e. master + workers. This option is most usefully combined with ``-n`` to allow individual models to be farmed out using a Message Passing Interface (MPI) task farm, e.g. to create a B-scan with 60 traces and use MPI to farm out each trace: ``(gprMax)$ python -m gprMax user_models/cylinder_Bscan_2D.in -n 60 -mpi 61``. For further details see the Parallel performance section (http://docs.gprmax.com/en/latest/openmp_mpi.html)
-``-benchmark``        flag    switch on benchmarking mode. This can be used to benchmark the threading (parallel) performance of gprMax on different hardware. For further details see the benchmarking section (http://docs.gprmax.com/en/latest/benchmarking.html)
-``--geometry-only``   flag    build a model and produce any geometry views but do not run the simulation. For example, this option is useful for checking the geometry of the model is correct: ``(gprMax)$ python -m gprMax user_models/heterogeneous_soil.in --geometry-only``
-``--geometry-fixed``  flag    run a series of models where the geometry does not change between models, e.g. a B-scan where *only* the position of simple sources and receivers, moved using ``#src_steps`` and ``#rx_steps``, changes between models.
-``--opt-taguchi``     flag    run a series of models using a optimisation process based on Taguchi's method. For further details see the user libraries section (http://docs.gprmax.com/en/latest/user_libs_opt_taguchi.html)
-``--write-processed`` flag    write an extra input file after any Python code and include commands in the original input file have been processed.
-``-h`` or ``--help``  flag    used to get help on command line options.
