[Blind-sysadmins] ACL editing tool?

Hi, so I'm working on a new network project. I have a Foundry FI400 core with lots of access switches using spanning tree and a pretty standard setup. However, there are some ridiculously large ACLs applied to several of the interfaces. I'm looking for suggestions for ACL editors or management tools. I'm also open to process by hand if anyone has any suggestions. I'm having a hell of a time remembering 300+ lines though to edit properly. Thanks Scott
