/*
Read in the configuration for MASSCAN.
Configuration parameters can be read either from the command-line
or a configuration file. Long parameters of the --xxxx variety have
the same name in both.
Most of the code in this module is for 'nmap' options we don't support.
That's because we support some 'nmap' options, and I wanted to give
more feedback for some of them why they don't work as expected, such
as reminding people that this is an asynchronous scanner.
