From README: Aclgen is a tool to create minimal length ip access lists and aggregated routing tables primarily for Cisco routers. Aclgen is fast. It takes only 15 seconds to create a 17000 line long access list for some 44000 entries of my routing table. Aclgen is flexible. It accepts various input formats and you can specify any output format by a printf like format-string. Aclgen is intended to use in large scripts creating router configuration from different databases. Any contribution is welcome. Send me your script using aclgen. I'll bundle it with the program.
