Cleanup leases?

Hi,
Attached is a perl script to clean up lease files. It takes the
current lease file, cleans it per the arguments, and writes out
a new file that you can move into place WHILE dhcp is shut down.
Be *sure* that all DHCP servers are shut down and quiet before
monkeying with your lease files. Be *sure* that all of your
DHCP servers have the same lease file before starting DHCP back
up. Use at your own risk, etc, etc.
For public areas where people/laptops come and go, lower your lease
time. Our pubic areas like our library have lease times only in
the few-hour range.
