@section introduction Introduction

This is dhcpd-pools ISC dhcp shared network and pool range usage
analysis.  Purpose of command is to count usage ratio of each IP range
and shared network pool which ISC dhcpd is in control of.  Users of the
command are most likely ISPs and other organizations that have large IP
space.

Program is written C. Design goal is to get analysis done quickly where
there is lots of data.  On cheap laptop the speed of analysis is roughly
100k leases per second.  Number of ranges, or shared networks, does not
make any significant difference in getting analysis done.
