Is is worth keeping? --- Information for https://cdn.openbsd.org/pub/OpenBSD/snapshots/packages/amd64/hlfl-0.60.1p0.tgz Comment: high level firewall language Description: hlfl (High Level Firewall Language) permits writing firewall rulesets using its high level language, and transforms them into rules for real software, including IPFilter, ipchains, Netfilter and Cisco IOS. hlfl attempts to make the best use of the features of the underlying firewall, such that a conversion from stateless to stateful requires no modification to the original script. hlfl was initiated by Renaud Deraison, co-founder of the Nessus Project.
