+define Package/resolveip/description
+ This package contains the small resolveip utility which
+ can be used by scripts to turn host names into numeric
+ IP addresses. It supports IPv4 and IPv6 resolving and
+ has a configurable timeout to guarantee a certain maximum
+ runtime in case of slow or defunct DNS servers.
