The --quiet option currently works by rerouting standard out to /dev/null. This was a hasty solution to the mass cluttering caused by using the multi-threaded option. Ideally, it would check for the quiet option each time before printing anything so that messages can bypass the quiet option when needed. This is mostly only a problem with the Chyoa script, as it may need to print and accept input from the terminal (currently worked around, but this causes issues in multi-threaded mode).
