# test_a_neuronoptions.py named to be first test file in this folder.

# neuron will already be imported and this test will not be substantive
# as it relies on being the first code to 'import neuron'. If neuron is
# already imported, a warning will be raised.
# This test trivially increases NFRAME by a small amount and tests
# that increase. Should not affect other tests in this folder.
# When this test was written, default NSTACK=1000 and NFRAME=512
