Those of you lucky enough to have already looked at the symbol commands may have noticed that there are a number of neutron debugging options. None of these are useful for gathering physical neutron data, and therefore they will not be described here. Some of the options can also be mishandled. The default values of these debugging flags are all $off, and few symbolic commands have been written for these options. They are not intended for the average user. If you are interested, I suggest that you look in the following FORTRAN files (which are part of the neutron code in SNOMAN) - VX_NEUTRON (debug energy options) and NEUTRON_MEDIA (debug media options). DO NOT ENABLE THESE OPTIONS WITHOUT DEEP THOUGHT!
