This script allows Mudlet's mapper to do autowalking on Avalon. To get started, clone the repo (or download it as a zip), then install avalon-mapper.xml as a module in Mudlet.
The script is open-source and worked on by myself, currently; but I do accept and encourage contributions. If you would like to add something, you can submit a PR. If you have an idea or find a bug, you can add a ticket.
