 This exports a model in a mixed JSON/ACC format analogous to that in the example directory of Arbor at ``python/example/single_cell_bluepyopt/l5pc``. The whole set of steps to construct and export the model is automated in the script `generate_acc.py <https://github.com/BlueBrain/BluePyOpt/blob/master/examples/l5pc/generate_acc.py>`_, part of BluePyOpt.
