Perl (any system supporting perl)
Version: First Release
Prometheus borns as a tool for Mac OS X system firewall configuration (eredited from FreeBSD IPFW); it is wrote in Perl.
It is really versatile and it has two ways of configuration:
1) Step by step configuration, for novice users (by a series of simple questions, it automatically configures firewall rules)
2) Manual configuration, for expert users (read rules directly from user input)
Next releases, will include a independet rules library, to give a more complete list of rules to novice users, a firewall log parsing and search function, for system administrators and maybe a GUI.
