SUMMARY = "An IP address pool manager"
DESCRIPTION = "IpPool is implemented as a separate server daemon \
to allow any application to use its address pools. This makes it possible \
to define address pools that are shared by PPP, L2TP, PPTP etc. It may be \
useful in some VPN server setups. IpPool comes with a command line \
management application, ippoolconfig to manage and query address pool \
status. A pppd plugin is supplied which allows pppd to request IP \
addresses from ippoold. \
