Test::TCP::CheckPort - check if a port is open from command line

       This is a wrapper for Net::EmptyPort which checks if a given port is open, from the command line argument
       (@ARGV). Because it works with port numbers in the argument list, you don't need to quote it when running
       with the perl executable.
