# NAME
# multi-ping - IPv4 and IPv6 ping tool
#
#
# SYNOPSIS
# multi-ping [ -h | --help ] [-m | --manual] hostname
#
#
# OPTIONS
#
# -h, --help Show a help message, and exit.
#
# -m, --manual Show this manual, and exit.
#
#
# ABOUT
#
# The multi-ping tool is designed to be IPv4/IPv6-agnostic ping tool,
# which removes the need to know if you're pinging an IPv4 host or an
# IPv6 host.
#
# The tool works by resolving the hostname specified upon the command line,
# and invoking "ping" or "ping6" upon the result - using the correct one for
# the address family which has been returned.
