I don't feel like giving a super big write up, so just look over the README and dive in. I'm releasing it way before I really want to, but I'd rather get it out there than never release it.
I ported most of my Mudlet system to Nexus. It's meant to fully support multiclass and serverside aff/defs. Figured it would be a decent opportunity to help out the community a bit by making it public, so have at it.
I have been fighting on it for a little while now in Runewarden, but I have been the only user/tester so far.
This is a pretty beta version, but feedback and criticism are welcome. I still have a number of things I want to do before I release something that I will actually support, but I will try to help out where I can if you decide you want to use it.
I have included some other small packages (Local Custom Settings, Bombs, Sigils, Tattoos, and Walls)
