+# NAME
+#   multi-ping - IPv4 and IPv6 ping tool
+#
+# SYNOPSIS
+#  multi-ping  [ -h | --help ] [-m | --manual] hostname1
+#
+# OPTIONS
+#
+#  -h, --help              Show a help message, and exit.
+#
+#  -m, --manual            Show this manual, and exit.
+#
+#  -v, --verbose           Show verbose errors
+#
+# 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 which has been returned.
